Apple notes of the following network compatibility on its website:
AT&T and T-Mobile
The iPhone for AT&T and T-Mobile does not support CDMA and will not work on Sprint or Verizon Wireless. It will use 3G cellular technology for voice services and either 3G or 4G LTE cellular technology for data services. However, the iPhone for AT&T and T-Mobile can roam internationally on many GSM carriers around the world.
Sprint, Verizon Wireless, and SIM-free
If Sprint or Verizon Wireless is your wireless carrier, your iPhone will work on AT&T and T-Mobile once activated. The SIM-free iPhone will work with any carrier. An iPhone activated on Sprint or Verizon Wireless, and the SIM-free iPhone, also have the ability to roam internationally on GSM networks.
All iPhone models are world phones, so you can use them almost anywhere. Which means you can roam internationally on GSM networks in over 200 countries around the world, whether you are a GSM or CDMA network customer. Availability of LTE data varies in some countries and depends on carrier support for certain LTE radio frequencies. For details on LTE network support, please see www.apple.com/iphone/LTE.
