Why there is no 2G?: Due to recent mobile network upgrades and the complexity of the technology your phone needs to be at least compatible with the carrier 3G H+ or 4G LTE bands / frequencies. Note that since 2017, AT&T does not operate in 2G anymore.

Partially compatible: This means you will get signal where carrier’s antenna runs on your phone supported bands. Connectivity may vary depending of the exact location. This compatibility is not recommended.
