Through a long process with Cingular, they have finally issued me a subsity code for unlocking 7100g Blackberry. They told me that using a different SIMS card in foreign country I would be asked to enter Subsity code after phone rebooted. Well, I inserted new SIMS and, was not prompted to enter subsity code at all. Where should I insert this 15 digit code and make it work?? Got a couple ideas what to do with Cingular.... Any help here ?? Thanks....Gary

That would work on a plan old cell phone, but not on a BlackBerry.

Instructions on how to unlock 7100t

That should work...

** Be careful - if you enter an unlock code incorrectly 5 times, the device is permanently SIM card locked **
