A:Answer No. This is a Verizon "Branded" phone, Verizon does not "lock" phones like other cell phone carriers, so it can be used with almost any carrier, but this is primarily a CDMA phone, NOT a GSM phone. While it may work with a GSM carrier (T-Mobile or AT&T) it does not have access to all the frequencies that a typical GSM phone would. Coverage and reception quality would be greatly reduced. Your best bet is to look for "unlocked" phones, as they have transmitters and receivers for both GSM and CDMA (NOTE: not all "unlocked" phones are CDMA capable, please use caution when researching options, as some manufacturers bury this deep in the specifications or descriptions)
