Carrier Compatibility

In the United States there are four major carriers who own and operate cellular networks including AT&T, Sprint, Verizon, and T-Mobile. Other carriers are what the industry calls Mobile Virtual Network Operators, or MVNOs, who rent cellular coverage from one of the four major carriers to provide their customers wireless service.

At Wireless Flix, we sell devices that are one of the following three variations of compatibility: 

  1. GSM and CDMA Unlocked: Works on all four major networks
  2. GSM Unlocked: Works on AT&T and T-Mobile’s networks
  3. CDMA Unlocked: Works on Verizon and Sprint’s network

We offer a large variety of carrier unlocked devices. Please note that it’s important to choose your specific carrier when purchasing a Wireless Flix certified pre owned device, as we can only guarantee it to work with the selected carrier. For example, we can only guarantee that a Wireless Flix certified GSM Unlocked device can be activated on AT&T & T-Mobile or their MVNOs; we cannot guarantee that it can be activated on any other carrier and we cannot guarantee that it can be unlocked.

We can also only guarantee that your Wireless Flix certified pre owned device will work domestically within the United States. We cannot guarantee that it will work internationally.

Our unlocked devices are generally GSM & CDMA compatible and will work on all major US carriers (Verizon, AT&T, Sprint, T-Mobile) and most MVNOs. Unlocked devices may not work in non-LTE coverage areas. For international travelers: Unlocked phones will work on most international GSM networks, but may have limited access, depending on carrier.
