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.
2G / EDGE: Enough for calls & texts. Internet will work very slowly.
3G H+: Suitable for most usage such as GPS, email, photos, videos, social medias…
4G LTE: Better for live streaming and heavy video usage.
