A Blackberry Pearl 3G 9100 unlocked works on all GSM networks. Unlocking a Blackberry Pearl 3G 9100, however will require an unlock code. Most GSM or SIM based phones come with a SIM lock by default that prevents them from working on “unaccepted” carriers. So if you wanted to switch your phone from AT&T to T-Mobile you would have to remove this SIM lock first.

As started earlier first, you will need your Blackberry Pearl 3G 9100′s unlock number. You can sometimes get a free one generated by your carrier. In exchange they will need your IMEI number, which you can get simply by entering *#06# and pressing enter. If you cannot get a free one, then try reviewing the extra unlock code service I have posted below.

Follow these instructions to remove the SIM lock on your Blackberry Pearl 9100:
