6230 calling problem PLZ PLZ PLZ someone help!

[mobile007]

First im sorry if i have posted in a wrong thread and second im really sorry if i am repeating a same question by any1 else but i couldnt find it anywhere who had the same problem as me.

i been using my 6230 on t-mobile for about 7 moths now perfectly and never had any problem until 5 days ago.

I decided to unlock my phone to all networks using the calculator and infact it worked.

I could put in my orange and o2 sim card and use it too.

I have been using it for 4 days without any problem until yesterday i dont see any network anymore.

When i put in my orange sim and also o2 there is no network and i cant even call!

After that i put in my orignal T-mobile sim and guess what i see the network but when i make a call it just beepz 3 times. Basically i can't call anyone or receive any call.

I purchased the phone for £180 and it was second hand and i had to buy a t-mobile sim.

Have i been cheated in anyway. oh i just feel really bad now cause i cant use my phone in anyway.

I'd be really grateful if anyone can please help me.

Thank you all.

your phone has been blacklisted by the network. on 02 and orange you will get no network and a 'sim card registration fail' message. t-mobile and vodafone gets the three rising tones. if you bought it second hand its possibly been reported stolen or the old contract is unpaid.
hope this helps
