Connecting to US cellular networks

The Fairphone (Gen. 6+) sold in the United States is fully unlocked and supported on T-Mobile and AT&T networks. 

To ensure a seamless connection, T-Mobile and AT&T customers may need to contact their carrier to have their device activated on the network. 

Fairphone models purchased outside of the United States require network compatibility verification using your phone IMEI when connecting to US networks. To use a Fairphone purchased in Europe within the United States, contact your network operator directly to verify phone IMEI compatibility.
