Sprint iPhones are among some of the most compatible devices on the market today.
Typically, Sprint phones run off of CDMA technology which is a technology incompatible with the majority of service providers in the United States.
The good news for Sprint iPhone 6s owners is that this phone has been designed with GSM capability. GSM technology is a prominent network technology used widely across the United States as well as the rest of the world.
The GSM portion of your phone will come locked from Sprint which means you'll need to have the device unlocked before you can use the phone with another service provider. Unlock the GSM slot by contacting Spring and requesting the SIM unlock.
Once the phone has been unlocked, you can consider using a number of carriers that are compatible with CDMA and GSM technology. To make things easier on you, we've created a list of compatible carriers who currently support Sprint iPhones.
