The V SQUARED will be available “unlocked” and work on US domestic and international GSM networks. You will simply put your current SIM card into your new device to activate it.
U.S.A. GSM Networks include T-mobile, AT&T, and others.
CDMA Networks will not necessarily require a sim card, such as Verizon and Sprint. (They’ll need the unique identification numbers from your phone to activate it in their respective networks.)
The V SQUARED will go through each network certification process before it is to be carried and supported in their stores.
