Hi Mr. othmansuseno,
I have problem with my bb8320 it was registered with T Mobile Austria and it is now unlocked only for calls and sms but not the internet... My provider told me that they can't register it for BB service unless unregister with T Moblile Austria, T Mobile don't want to unlock it as I am not their customer...they sad that phone is registred with PIN
I have tryed all the unlock methods but no luck...maybe I should change the PIN?
My current PIN is 2529CE34
and IMEI 004401.13.272524.9 (but this is after unlock, previously it was 35281016190330)
Many thanks,
Mihajlo
