That was one of common unlocked blackberry problem, try to reinstall your unlocked blackberry curve 8300 software since blackberry unlock code only unlock your phone network configuration, all your remains software still use your old carrier network setting.

Hello, make sure your blackberry phone already unlocked using blackberry storm 9530 unlock code. To test your phone already unlocked or not is by replace that original sim card with another sim card from other network provider. If you can't make a call using your new sim card maybe you have wrong blackberry unlock code, which mean your phone not yet unlocked. But if your phone already unlocked you can download att mobile browser by following a certain step from here. I hope it can solve your problem.

ASKING FOR PUK code for blackberry curve 8520


The PUK-code is not actually bound to what type of phone you have, but to your SIM-card. This code usually can be found together with the papers you got when you first got your SIM-card. If you can't find it you can try to contact the operator, e.g ATT and ask them for support. They can usually give you the PUK-code if you give them your personal info.
Good luck! And please, if you do find this answer helpful give it thumbs up :)

I need an unlock code for my Samsung phone so I put the SIM card in my new blackberry curve.


If your Blackberry Curve is already unlocked, then you would only need to pop-in the SIM card from your Samsung L700 onto your Blackberry Curve.

I have a Blackberry 7280 AT&T provider and I'll like to unlock to use it with T-mobile. Can somebody help me to unlock it? Thanks


Easiest way to get ATT to give you the unlock code is to tell them you are going overseas (Europe is a good generic choice) and youn want to use a local sim card. They will provide you with the unlock code and instructions on how to enter it. If you got the phone from a 3rd party, simply call att 18003310300 and let them know you got an att phone from a 3rd party and they will unlock it for you.
