BlackBerry Pearl 9105 unlocked works on all GSM networks. The BlackBerry Pearl 9105 is requires an unlock code because it uses a SIM card. By default, most GSM or SIM based cell phones come with a SIM lock that prevents them from working with “unaccepted” phone carriers. Therefore, by removing the SIM lock you can use your BlackBerry Pearl 9105 with any GSM phone carrier you want (such as AT&T or T-Mobile).
