About 2G: Since January 2017, AT&T has shut down his 2G network to release more bands for 4G and future 5G. Therefore your phone needs to be at least 3G compatible with AT&T.

Partially compatible: This means you will get signal where carrier’s antenna runs on your phone supported bands. If you plan a road-trip connectivity may be variable.
