What You Get Samsung Galaxy A25 Charger Documentation Unlocked phones are cell phones that are independent and not locked into any carrier's network. They can be activated on any carrier that operates on a corresponding network, either GSM or CDMA. GSM carriers include AT&T and T-Mobile. CDMA carriers include Verizon, Sprint, Virgin Mobile and Boost Mobile. A GSM phone cannot be activated on a CDMA network and vice versa. To begin using an unlocked phone, a carrier must be chosen, and, for GSM carriers, a SIM card purchased for that carrier. This phone does not come with service activated. This phone does not include promotional minutes.
