Mystery about Privider phones solved!

[gsm community]

Did you wonder why codes for Nokia DCT-4 phones like 3510i from Virgin UK or Debitel Denmark couldn't be unlocked?

Here is the reason: Wrong provider code!!!!

This is instruction file for Nokia production

I marked the important data

SIMLOCK_IO_FILE_VERSION_V0.3

The same thing for Debitel Denmark, they use multilock feature, simcards from networks 23801 AND 23802 are allowed, but only certain simcards with certain GID1 values

The CONFIG_DATA value is the right value for calculation!

Provider Code Debitel Denmark 23800
Provider Code Virgin UK 23400 (This is for 3510i)

Provider Code FIDO 8390/7210/etc. still under research
Provider Code AT&T 3650 still under research
Provider Code T-Mobile US 3650 still under research

Could this people, who successfully unlocked their phones, that are still under research, please post IMEI and correct unlock codes? Thanks!

To read out your configuration data you can use this method, too http://nokiafree.org/forums/t31957/s.html


Additional info:

A new trick or fault from nokia! Virgin phone 3510 for T-Monile UK network, but network code has to be 23433 (Orange)! You don't believe that?

You wonder where I got this infos? Very simple. The service partner flash files normally don't contain the simlock i/o files, but for 3510 and 3510i they always do.
