how to close a simlock in 3310?

[snp]

hi there!

can anybody can tell me how to close a level 1 (operator) simlock in 3310? what program should i use and what should i do? i was tryin' with rolis and jordik, but after closing i've got: sim card rejected.

thank you in advance

[cprafferty]

Well I guess that because you failed to enter what provider you want it locked to.

For Poland (put the number in the box next to the lock button)

PLUS GSM - 26001
ERA GSM - 26002
IDEA Centertel - 26003

[Nanda]

You should find out your full 5-digit operator code, like cprafferty said.

The first 3 digits are your country's digits - they identify the operator's country of origin (724 for Brasil, for instance).

The two last ones are your operator's identifier (31 for Oi in Brasil).

Thus, Oi's phones are locked to 72431, for example)

To find out your operator code access http://www.gsmworld.com/roaming/gsminfo/index.shtml and check "GSM roaming". There you'll find a list of all countries that use GSM networks and the operators on each of these places, with their respective codes.

Hope that helps.

All the best,

ok, that's seems to be a solution. is it possible to change this particular lock's value to 'factory'? gammu shows me 'user' value. i would like to hide the fact, that i was playing with simlocks =)

[User32]

How can i lock the 4th lock? where can i see the sim's serial number?

[Sinister Frog]

user32: i dont think we'll ever get that question answered properly :)

[KnOeFz]

I posted 4th lock solution a while ago... you need to use winlock software... search old topics and you'll find detailled instructions with software attached.

-=K=-

[snp]

ok, but winlock requires original nokia service stuff, am I right? maybe there are some emulators for fbus data cable?

[User32]

I've found a prog 2 months ago that works only with ericsson. but i have nokia!

[snp]

I've found a prog 2 months ago that works only with ericsson. but i have nokia!

you mean it's doing what it is meant to do under nokia? cool.

[Kilrah]

Nokia tool 1.8 by Rolis should be able to close all locks (I have only tried lock 1 and it worked).
To find the SIM's serial number I don't know yet, but I have a card reader at home and I'll have a look at my SIM's files this evening... I had also thought about it... then if someone steals my phone, he won't be able to use it anyway without unlocking it:D. And thieves don't often have what we do... :grin:

[snp]

is there any possibility to get to sim card's beats 'n' pieces without external sim card reader (using phone's internal reader)?

[Kilrah]

In fact it's the same thing again... Of course it could be possible, but nokia did not implement these functions, as far as I know. You can get the SIM's phonebook and SMS directory, but this must be done by the phone's software. I don't think there is a way to access the SIM directly.

I could be wrong, and I would nearly hope it, because it would be very useful! (if someone could please correct in this case...)

Regards
Kilrah

[User32]

you said: nokia did not implement these functions.
Then, why doesn't the phone ask for the security code whenever we turn it on? how does it recognize that it's the same sim card? there must be a place in the eeprom in which there is the sim's serial number.

[Nanda]

Hi everyone,

I'm not sure if this is what we're all looking for (SIM S/N), but all my operator's simcards come with a sequence of 19 digits printed on them.

On the SIM blister case, there's a sticker with 18 of these 19 digits, marked ICC ID. Is that the number we need to lock the phone to a particular SIMcard?

How can I test that? I have a 3310 and a 3410 with f/m bus cable (no flasher cable yet).

What lock are we talking about here (lock 1, 2 etc) and what would I need to close it? (in terms of software and procedure).

I'm a beginner and I'm not sure if this is it, so please keep me posted.

Thanks!

[User32]

We're talking about lock 4, but the number i'm looking for consists of 10 digits.

I've seen the 19 digits you're talking about; my sim has them too.

[Kilrah]

In fact I've never seen this security code thing... I've changed SIM in ny 3 nokias, and never had to enter the security code :rolleyes: and I was talking of functions to access the SIM directly through F/Mbus. So maybe it's possible.. should try to store eeprom, change sim and store eeprom again, then compare!

Anyway, I had a look yesterday in my SIM's files, and I didn't find any MSIN entry like the name of lock 4. I could get the SIM's serial number, which was a very long dec number. I tried to convert it to hex, but it was still much too long (about 18 digits, maybe it is the same as the one which is written on the SIM, didn't check as I just read nanda's post). There was a file called MSISDN, which had 4 entries, but all too long. In fact it is not the problem of closing the lock, but to find which number to close it to...

Also had a look at locks 2&3, as there were files called GID1 and GID2 in the SIM, but GID one was FF FF FF FF FF FF FF or something like this, and GID2 not available. So no way here (for my SIM of course)...

I tried with my IMSI, which also is too long... should try removing the 4 first bytes(MCC+MNC)...

Anyway, I tried to close lock 4 several times with different numbers (with nokiatool 1.8 ) and always got 'sim card rejected' message... unlock again!

I'll give it some more tries today;)

@Nanda:
You need Nokia Tool 1.8 by Rolis and mbus cable. I don't use later versions coz they are unstable. Sometimes with 1.8 if the phone is on and you do a command (open/close/clear), it says 'done' but if you read the phone again nothing has changed. I just power off the phone, power it on again and immediately send the command befor the 'enter pin' message. Works 100% in this case.

Kilrah

[snp]

it looks like with kilrath and his marvelous sim reader we're getting closer to the 4th simlock mystery solution =) good job my man!

[snp]

uh, and gids - those are group ids, so they're managed by the phone. lots of FF means it full or without change. it should be. and what does MSIN means anyway? mobile sim identity number? so it's something like imei for a mobile. maybe it's coded in some way, like msid is?

[Kilrah]

Well...

I've just been searching in my old pages about SIM emulation (those I was using when I had my first motorola :wink: ) Quite funny to read this again... thanks! :p

Found some interesting things:

1) ICC ID is the SIM's serial number, with some modifications. It is a 20 digit hex number, where the first 2 are always 89. If you read it raw from the SIM, it is lke all the SIM data, always with inverted nibbles (eg. if on your SIM it is printed 89 41 03... like on mine, in the card memory you will read 98 14 30...).
You get the card serial number by removing the 3 first bytes of the ICC ID and discarding one nibble like in the example here:

ICC ID (memory form) SERIAL
98 43 70 02 00 00 98 03 51 F3 20000 0893015-3
|______|
Remove this and reverse the digit pairs of the following digits.
The last digit after this operation (last 'F') is unused.
That's 13 digits now. Still too long. I tried to convert this example's serial to hex(could be dec here) and the result is... euh.. no good hex calc here and windoze calc suXX.. overflow..:mad: maybe a 10 digit number:p (can someone calc plz:rolleyes: )
still hoping..

btw... could you have a look at the number written on your sim and see if the 2nd and 3rd byte (if we assume it's hex..) are your country calling code (like +41, but without the + ;) ) and your MNC respectively plz.. (for me the number is 89 41 03...... and in switzerland code is +41 and my MNC is 03 (Orange)).

2)The IMSI (your customer number) is 9 bytes long, so 18 digits. The 1st byte is always 08 (memory form), then 3 bytes for MCC+MNC, so for me 08 29 82 30. if we 'decode', we have:
80 92 28 03. The 809 is fixed in any SIM, and my MCC is 228, MNC 03. It works. If we remove these 4 bytes... we have a 10-digit hex number! :cool:

So now I must try this tonight and see which solution is the good one (if it actually is one of these 2 :rolleyes: )

The funny point is that I've not seen once the word MSIN yet... don't know who found it.. must ask Rolis :P

@snp: IMEI for mobile ~= IMSI for SIM

Well, this post is already much too long and it's 45 mins that I'm writing it.. so I'll stop for the moment :D

If someone has found something... post!

btw once more: what is the use of GIDs? seems they are not really used, I think these FFFFs just indicate an empty location..

Regs
Kilrah

[snp]

GIDs - Group ID. i'm not sure, but it's probably got something to do with your phone groups. i've never ever tried setting groups in my nokia, but it seems that you're able to close lock to chosen group, so no one outside it can boot the phone. it's somewhat stupid on the other hand. or maybbe i'm completely wrong =). anyway good job kilrath. but how can i found sim's serial number without sim reader?

[Kilrah]

Yeah!

found info about MSIN!
In GSM 03.03 standard (deals about identification), everything is described.

IMSI has 3 main parts:
MCC - MNC - MSIN (Mobile Subscriber Identity Number)
IMSI means International Mobile Subscriber Identity
quite logical in fact..

So as I said in my last post, taking the IMSI and removing the 4 first bytes would do the job. It remains 10 digits that you just have to enter in NokiaTool:p :p

As this solution seems to be the one, I will describe a bit more IMSI decoding. As I said, the nibbles are inverted in SIM memory. So here is an example:
IMSI = 08 29 41 70 01 00 26 68 47
Decoded IMSI = 80 92 14 07 10 00 62 86 74
=809 214 07 1000628674
You remove the 3 first digits that have been added by someone, (either SIM manufacturer or who else, because according to the standard an IMSI may not be longer than 15 digits).

Then the 3 next ones are your MCC, the 2 following are the MNC, and the 10 last are... the MSIN! Got it!

Now the thing is how to find your IMSI... either you buy a reader, or you make one (see SIM cloning section, they know about it as they have to read it...), or maybe there are other solutions:
On (old, don'know for new ones) motorola phones' test options (like engineering monitor on nokias), there was a field which displayed the IMSI on the screen. Now for nokias, apart from TMSI, I didn't find anything... maybe a software could get that info through mbus... but I've never seen one:(
Maybe it is somewhere on your monthly phone bill, I just don't know!

Anyway, if I find something new, you'll be the first to know;)

[Kilrah]

Found a site where it was explained that there was something called AT-Commands used for communication between a phone and a terminal connected to it, like a PC :D
I downloaded the GSM norm about this (GSM 07.07) and found that these commands are here to control the phone with an external equipment. Examples are read/edit/add of phonebook entries, SMS, set time, and lots of other things about UI, network and system management.
What I found that is so interesting is a command that allows DIRECT communication with the SIM:D :D
So just what we needed! In fact the phone receives the command by a serial interface and sends the parameter of the to the SIM. Then it sends back the card's answer.

Looks great! The small problem is that support of most of the features, including this one, is optional. So it would be worth testing! We have to do a program that sends commands to the phone and see if they are accepted. As I think, they can be sent through both FBUS and MBUS, as logomanager and other proggies like this can use both..

Well, if someone is a beast in programming under Win with serial port access, it would be worth trying! I know how to program, but it takes me too much time, and I know that others can do in 1h what I do in 1 week... so if one of them reads this... just contact me for documentation and other info!

It's also useful to read GSM11.11, as it contains details about the SIM card communication protocol (T=0).

[snp]

hey, but nokia 3310 doesn't support hscsd, wap or gprs, so it doesn't support at commands in 'modem' sense. i think that this should be done by fbus/mbus data transfer standards (if possible)

[Kilrah]

That's what I was meaning.. at the beginning I thought that AT commands were modem-related so I never interested myself in this... but what I've seen today just changed my point of view: they have absolutely nothing to do with it!
These are commands to control the phone, but nothing is specified for the interface apart that it must use serial communication! so it's valid with all phones by the way the manufacturer decided it.. that's F/MBUS for nokia

[Nanda]

Uhm... I thing I got a problem...

I tried a number I thought could be the SIM serial and used Rolis 1.8 to lock it... Now it refuses to open the lock back again!

The thing is, Nokia Tools by Rolis never unlocked my phone, it was always ever good for LOCKING... What other program can I use to unlock this???????

Help!!!!! My phone won't read any SIMs!

[User32]

try knok. this prog i use for updating faid and (un)locking.

[User32]

i've calced the 14 digits that remain after we remove the 3 bytes... now what? the hex number is 10-digit but it doesn't work.
the number on my sim is 89 30 01 00 01 01 11 06 70 01. can you do something ?
ah, and.. can you tell the AT commands? i wanna give 'em a try...

thx

[Nanda]

Hi

Thanks for the help, I managed it.

But now there's an annoying bold-lettered "1" right by the signal bar on the display.

How can I get rid of it?

Thanks!

[User32]

since i don't have a sim reader, is there any relation with the msid? does this help at all?

[snp]

nanda: have you got ALS enabled? press and hold # to check it (you should get 'change line?' message). if it so, you have to change product profile bit, but currently i don't know which one.

[Kilrah]

Done it!
Successfully locked my 3310 for MY SIM!

I just answer your questions first...
@Nanda: To unlock with noktool try my method of reading phone info, then power off, power on again and about 1 sec later click 2-3 times on 'clear sp locks' button. If it doesn't work try again. I've locked and unlocked my phone about 10 times like this yesterday...
For your line 1 sign, I had the same after a factory reset. Use NokiaProfile(you must have logomanager installed and configured) and activate ALS. It will then be OK.

@user32: Unfortunately no link between IMSI and serial. However, I just noticed that I could find the last 2 bytes of the MSIN in the serial by a weird nibble manipulation, and it worked with 2 SIMs I have. Maybe there is a way to find the 3 others... will keep trying.

OK, so I got it right. I'll give a little step-by-step method, as I found that you can't close lock 4 only - it will always reject your SIM.
So:
1) Close lock 1 to your MCC+MNC.
2) Get your MSIN by the way described before (remove 4 first bytes and reverse nibbles of the 5 last ones).
3) Close lock 4 with this MSIN.

Done :p

It is necessary to close lock 1 BEFORE, otherwise you can't close it without opening lock 4 again.

For the AT commands, I gave it a try, but could not get any answer apart from the echo when using MBUS - normal for a single-line bidirectional interface. But I only had a siemens guide, so I have to look for one about nokia... I even din't know what baudrate to use... tried a bit everything, but nothing worked. Don't have the description here as I'm not at the same place today but I will post it tomorrow. (And try more of course :P )

Bye for now!
Kilrah

[Kilrah]

Ah forgot this:

Had confirmation about 2nd and 3rd bytes of (decoded) serial:
2nd one is country calling code and 3rd one is MNC. Worked witn 3 SIMs.

I could also give the info for the 2 last bytes of IMSI:
IMSI (decoded): 80 92 28 02 07 10 07 94 69
Serial (decoded ICCID): 89 41 02 05 51 54 00 2 94 69 5

See the end of serial? the 94 69 is there.

Another one:
IMSI: 80 92 28 03 51 30 00 26 19
Serial: 89 41 03 00 11 61 15 0 26 19 3

Same for 26 19.

Can someone have a try for other relations on these 2 examples please? maybe +- operations..

Simple method to lock the phone to SIM card

1. Insert SIM card in to the phone
2. In Rolis Nokia Tool:
- read the phone info;
- mark lock's that you want to lock, set sim locks type to AUTO/FACTORY(USER) and close locks, DO NOT SET ANY NUMBERS!!!;
!!! if you want set lock4 you also must set lock1, otherwise phone don't locks !!!
- restart phone with 'SW reset' button in Rolis.
- after restarting enter PIN -> "SIM restriction on", your phone will be automatically restarted;
- now your phone is locked :) it's SO simple

If your phone doesn't locks, maybe Hard reset (Off/On) will be needed;

i've tried this method on 3210, 3310, 6210 and it work's 100%


BR,
Al

P.S. sorry for bad english

[User32]

i've heard this method 2 months ago but my problem is that i can't read my phone in rolis nokia tool with winxp. i've tried userport too but nothing! (ps: the phone is of course on)
how can i make this prog work in winxp??:confused:

[Al]

I use WinXP Pro v2002 with SP1(v.1081), userport, Rolis Nokia Tool v1.8 and it works perfectly.

[User32]

How can it be? I've tried everything and I still can't use it!

[Kilrah]

Hi!

@Nanda:
It depends what you want to do... the one I bought had a soft with it which could read all the SIM's files and display them, and I bought it after having carefully checked for that. In fact it is some proprietary thing, which only works with the soft it comes with :mad:
So I also built one myself (Had nearly forgotten it, it's because I talked about SIM cloning that I remembered I had it. That was yesterday evening...). I always used the other one because of the graphical UI of the soft... nicer than DOS progs! So I tested the one I made with SIM Scan from dejan and it works fine, and you can also read everything. The main difference is that sim scan can't write to the sim, so you can't edit your phonebook and everything... although there must be other progs to do this, have not searched yet. If you want, I can send you the doc. As I made it at school as a project (!), it is complete with schematics, breadboard design and parts list. The problem is that I won't be able to get my doc back before next friday as it's not at home...
If you don't want to wait but you want to build it yourself, download SIM Scan. There is a schematic by dejan with it which should also work fine.

@slikmik:
Looking for a way at the moment, will post results when I have some...

@Al:
Tried this, but when I set to auto and press close, it just goes back to factory and doesn't lock anything. Even when I power up the next time. I have a 3310 v4.02.

Regards
Kilrah

[Al]

On my 3310 v5.57 (now 5.59 :)) it works well.

After setting AUTO/FACTORY and closing locks you must restart your phone with INSETED SIM, after entering PIN code your phone automatically restarts and now your phone is locked to this SIM card.

[Kilrah]

OK, will try again.

Kilrah

[Nanda]

Hi Kilrah,

did you manage it? I have a 3310 v5.13 and Al's method won't work either!


@Al

Al, will that work on a v.5.13? I tried and tried and nothing! Don't I need SIM serial number to get this done?


Thanks guys!

[User32]

I think i found the cause of my problem. It's probably because i use an auto-switching f/mbus cable, while NokTool requires only a mbus cable. Please confirm me.

[Al]

@Nanda
I've downgraded my 3310 to v5.13 C, and it's also locks to my SIM card. You don't need SIM serial number to do this.

@User32
I think you're right.

[snp]

i've followed Al's instructions and it works! i've got v05.13, auto-switching f/mbus and win98se. please remember to close operator lock, when closing 4th. there's no need of entering any informations into rolis, just close the locks.

[snp]

and please remember all of you, that kilrath's findings are also important =)

[Kilrah]

Still haven't tried yet.... I'm quite never at home these days... and I try to find an internet connection everywhere I can to come and see here :)

Sorry...

Hi everyone,

I've tried Al's method over and over again and got nothing.

My no. 1 lock shows 00101 (unlocked) and my no. 4 lock shows 0000000001 (unlocked).

When I mark them both, choose AUTO/FACTORY and press 'close' Rolis says "can't read SP lock information" or something.

If I erase the numbers in any of these two locks (leaving the field blank) Rolis gives a Windows error message and freezes.

I'll keep trying but it doesn't seem to work for me.

I have a PC w/ Windows 2000 SP2, auto M/F Bus datacable and tried locking my 3310 v5.13.

Cheers,

[Al]

@Nanda
Can you read phone info with NokiaTool?? I think problem can be in auto M/FBUS cabel under Win2k, i use handmade manually-switching cabel, I don't trust any other :).

[snp]

nanda: just check your cable with jordik or knok to see if it's not damaged.

al: you haven't mentioned faid updating. it's also important. and after simlock closing, netmonitor has to be reenabled. anyway your method works just fine.

[Al]

@snp
FAID update isn't necessary when setting locks only when changing flash( MCU, PPM ).
netmonitor still enabled after closing locks at my 3310.

[snp]

al: i'll disagree with you. without updating faid, i've got no network.

[Al]

@snp:
Are you sure??? I lock my phone without updating FAID and it works fine ( finds network and no resets ).

[snp]

al: i'm sure. i've unlocked and locked again my phone several times (for testing) and with different programs (knok, rolis, eeprom tools). in any case faid updating was a must. anyway forget it. the most important thing is that your method works.

[User32]

It doesn't need faid update. it happens to me too sometimes. after (un)locking, turn on the phone and if you get no signal, wait for a few seconds. it will reboot itself and everything will be ok.

[Nanda]

Hi guys,

I finally managed to lock my phone to my SIMcard, I'm just not quite sure how I did it! :)

The fact is, after repeating Al's procedure a lot of times I just gave up, turned my phone off and disconected it from the PC. When I turned it back on, "SIM restriction ON" appeared on the screen!

I then connected the datacable again and made Rolis read phone info, and there it was, the SIM serial on Lock 4...

Well, I can only say I feel safer now, even though I believe thieves must have datacables too! In any case it was a good experiment. Too bad friends with dead batteries won't be able to borrow my 3310! :)

Thanks everyone and thanks Al and Kilrah and snp for your insights. Thanks to you guys this is one of the hottest threads on NokiaFREE, did you all notice?! :D

Well, if I get anything new I'll be sure to post it here... Now I finally got the original keypads I needed for my complete 3310 to 3315 project...

Best wishes to everyone,

[WildSwan]

@Nanda
We both have problem in searching for the Original 3315 keypad! :)

@EVERYBODY
Ironic, while others wants their phone to be "open line" so they aren't locked to a particular network, here we are trying to lock ourself into a network in order to lock our SIMs to the phone.

On the bright side, it's a security in a lighter sense. Infact I would like to do it on my 5210.

But this is not permanent right? Anyone with our knowledge can UNLOCK the protected phone.

Keep it up!

[Kilrah]

OK, I've finally had time to test Al's method, and it worked perfectly at the first time... Did it with nokiatool like always. Works in user and factory mode. This method is of course much more practical than mine because you don't need a card reader...
Anyway, I found very interesting to have a closer look at some of these long BCD numbers that we see everywhere in GSM world...;-)

btw...
@snp:
I did not have to update FAID, and my net monitor was still enabled.

@Nanda & WildSwan:
Of course if someone who knows how to unlock steals your phone he will unlock it in seconds. But that's another problem, more location-related. In some countries you find shops where you can have your phone unlocked at every street corner, and in other places like in my country, you can't find a place anywhere to do it. And not many people know it's possible... I knew it was some time ago, but had not searched for info about it before a friend came and asked me if I could do it for him. This is how I found NokiaFREE... Now I must thank my friend..:D
So maybe I'm more secure with my phone than you now! :razz:

Bye for now!

Locking phones can be useful, say if you make a revenue out of it (make money from unlocking phones) and someone asks you to unlock the phone, you do it, but then they decide it's too much or they don't have the money yet, you just lock it again when they insert their SIM. Just a reason, there are various others like Kilrah just pointed out (A country where not many people unlock mobiles).

Cheers,
-Dave

[Kilrah]

Yeah good idea! Didn't think about it! But you could also do something else from your point of view, like sell locked phones so that you can get money for unlocking them later!

Anyway, I don't think like that, and when I unlock a phone for someone (doesn't happen often btw), I do it for free.

Regards
Kilrah

[Shidoshi]

Hmm...

Well, in my case, I've invested a LOT of money on unlocking equiptment for the sole purpose of manking a little money with it, so I usually charge my clients a small fee ;)

15e isn't much, sometimes I even update software + convert 3310/15, etc. for the same price :)

OK. As I do my equipment myself, it only costs me a little for the parts, and some time, which I don't count as it is mainly for learning purposes.
In fact here it wouldn't make much money, because the only locked phones are sold with prepaid cards for a lowered price. And operators don't want too much prepaids anymore, so the communication prices are much higher than with the standard system. So people don't buy them, and the only market would be upgrading.

@everyone

Well, in my part of the world (Brazil) GSM has just started out last year, before that we only had CDMA and TDMA (one license each for each region or larger State). Now we have lots of regional TDMA and CDMA operators and two national GSM operators. GSM is MUCH better of course: when the first GSM network (Oi) began to operate, it expected to sell 70,000 phones in its first 2 months; it sold 500,000!

People here had no idea that their phones were SIM-locked until the second GSM operator started out earlier this year, and datacables are mostly unheard of. I've unlocked my phones and few friends' phones but since I don't know the operators' policy on unlocking (if they do it or charge an amount or something) I think I won't make a commercial operation out of it. Since until recently Oi didn't warn people that the phones were SIM-locked, I got more requests for different operator logos from friends than requests for unlocking. So I guess I'm pretty safe with my SIM-restricted phone for the moment!

What I do get is people asking me to 'change' their phones from GSM 1900 to GSM 1800. I explain: in the entire American continent, GSM operates in 1900 MHz, but Brazil is the only American country where the European 900/1800 MHz standards are used. So we get a lot of people buying Nokia 3390's when they travel to Argentina, Chile or the USA. Of course the 3390 won't work in Brazil, it's GSM 1900 only! And, of course, no flashing can change that, so I just tell them to sell their phones on eBay... :)

@WildSwan

Hi, I got an ORIGINAL 3315 keypad from a water-damaged 3315 I bought from an Australian on a site called sold.com.au. I'm about to finish my 3310 to 3315 project: I have the orginal keypad and faceplate, the flash cable and am only waiting for my Blue leds to arrive! I'll falsh my 3310 to 3315 and change its appearance as well. When it's ready I'll post pictures here! :D

[Nanda]

BTW, sorry for the loooong post!

So it's only one year that you have GSM! OK, and your first operator was clever enough to lock its phones, so he wouldn't lose its customers at the arrival of the second... Good! But I wonder why they have chosen European standard?!? maybe so you can't go and buy your phones out of the country without going far away... :mad: to this commercial industry... That's why we are here! :P

btw: you're excused for your long post... I'm used to them now :P
lol...

@Kilrah

Apparently they chose the European standard because of the greater phone choice and easier roaming with the rest of the world. Also, the two previous mobile systems were american. You can roam in a GSM 1900 network if your phone's tri-band. As for the ease of getting phones, GSM900/1800 phones are actually cheaper these days!

Anyways, here in Brasil nearly all things follow European standards: cars, electrical appliances, plugs etc. We drive small Fiats and peugeots rather than large american cars. :rolleyes:

Now I'll try to SIM-restrict my other Nokia, a 3410, and see what happens! :D

Cheers,

[Nanda]

AL's method worked perfectly and first time I tried on the 3410. On 3310s I always run into difficulties (like I explained before). :(

Any ideas why?

Thanks,

[Kilrah]

I never had a look on how many only-1900Mhz phones existed.. But it's true that it is easier to have 900/1800 ones, and anyway all the new phones which go out now are tri-band...

But I must say I sometimes prefer large american cars than ours :grin: (especially old ones... Ford Mustang 68...) :P

btw: is 3410 still DCT3? I thought it was DCT4 already

Kilrah

[Kilrah]

you posted while I was writing... :D

So must be DCT3... In fact 3410 and 3510 appeared here at the same time, so it must have confused me... btw we see very few 3410s here... maybe due to this...

@Kilrah

I'm not sure about the 3410 internal architecture, but its datacable attachment is the same as in 3310/15/30/50 and my datacable and Rolis worked with it. It must be DCT3 I think.

Yes it's a fact that 3410s are a rare sight, here in Brasil too, I think people just preferred the 3510 for its GPRS capability. Also, J2ME Java was very poorly implemented on the 3410. And since GPRS traffic remains totally free on Oi network 'til 31st December, people reckon 3510s are best...

btw there are a lot of GSM1900-only phones but from weird manufacturers like Kyocera, LG, Samsung etc. Usually the same ones that make CDMA equipment. GSM1900s are not sold here so I don't know much about them, all I ever saw were Nok 3390s that people brought from the US, Argentina and Chile... Looks same as 3310, that's what's confusing. ;)

[Kilrah]

You lucky! If only GPRS traffic was free here also! But it's horribly expensive (~7US$/Mb), so very few people use it...
But MMSs are free until the end of the year for 1 operator. As there are not many people who have MMS-compatible phones, they don't lose much... Would have been a good idea for GPRS because most of the phones have it now...

[User32]

here it's the opposite. i've seen very few 3510 while most people buy 3410. of course it's DCT3! it's mcu is based on the 3330.

Sorry to interfere... Does a thief will return your phone if they not able to unlock the phone? :D .... However, this is a good idea. At least they will get a hard time to figure out what to do with the phone. :D

[Kilrah]

No of course you won't get it back... or the thief is very stupid!
But the goal is that they can't do anything with it! I did the same with my motorola, you can ask for a code at startup... and even less people had the interface to read the phone prom the PC!

Well, in Brazil at least there's a national database of stolen phones' IMEI numbers and all SIMcard sellers must check that database before they sell a SIMcard to someone. You need to bring the phone you want to activate to the SIM shop, so that they can check IMEI. Not even a proof of purchase, such as the receipt, is enough these days.

If your phone's been stolen and you reported it to your operator, your IMEI will be on that database and in theory (IN THEORY!) no-one will be able to buy a SIMcard for it. Shops are also instructed to either retain phone or call the Police in such cases.

That's because GSM is less safe in this sense (stealing a phone and fitting a different SIMcard is easy). With CDMA and TDMA phone activation is over-the-air, you need to go to the operator shop and get it activated there using the phone's serial number - there's a national database for these too. In the end they just applied the same principle to GSM.

In theory that should have put people off buying stolen phones, but of course there are ways around these rules.

The point is, they just make it more difficult, like locking your phone to your SIM does.

[Kilrah]

Nothing like this here, and I know quite a lot of people who have had their phones stolen... But even with your system they could sell the phones out of the country...

Kilrah

[Nanda]

That's true...

And I myself switched to GSM after I had my old TDMA phone stolen. Well, lost in a club, but never recovered.

[User32]

Any ideas on how to make NokTool 1.8 to read my phone?? I've tried it on Win98 with my auto-switching f/mbus but nothing happened. What's the problem??? how can i put a switch in the cable?

[Nanda]

Did it stop working or has it never worked?

I sometimes get this problem, check if the cable is working by running other program, like Logomanager, and then try Nok Tools again. Not sure what causes the problem, though.

Hope this helps!

[snp]

user32: sometimes autoswitching cables won't switch properly to mbus after using fbus and vice versa. connect your phone, boot it and run rolis. this should help.

[User32]

@Nanda: the cable is ok. it works perfectly with logomanager both as fbus and mbus.

@snp: didn't work. should i use userport?

[snp]

user32: i've got win98 se, so i don't even know what the userport is =(

[Shidoshi]

Hmm...

There are some posts on here about auto-switching cables... I beleive that NokiaTool 1.7 works fine with auto-switching cables, I've had the same problem before last year or so, and I had to use some wierd/older program until the manual-switch cables arrived. Try searching for auto-switch on the forum ;)

Cheers,

[Shidoshi]

Hmm...

'Search and you will find!'

There is a schematic to convert auto-switching cable to manual-switching ;)

I would search it for you but I'm in a hurry to get to work. CYA! :)

Cheers,

[User32]

Can you please post v1.7 here? i can't find it in the forum. in the download section there is v1.8.

didn't read all those texts..

in finland, phones come "open".
sometimes it would be nice to have phone locked to own sim-card, sometimes network-specific.

but, if somebody steal my phone, and don't know how to unlock, he will just throw it to trash or use as spare parts.

in any case, i can't get my stolen phone back.

and if i report imei code to be stolen, if i find my phone, imei is still blacklisted long time until i can use my phone (if never).

best way to prevent phone being stolen would be using very old phone i think.
who wants to steal 5110 if you can newer phone from store almost free?

[User32]

what's the point of using an old phone if you want to have a new one?
