The ATT post-3G sunset compatibility list linked above often includes only US ATT-locked versions of phones, even when other carrier variants exist. Look at all the older Samsungs that only take the GxxxA variant when GxxxU and U1 devices exist that are carrier unlocked and have all the same bands. In the case of the OnePlus 6T, only the T-Mobile version is 'supported,' when the unlocked version is the same in all other markets (including the US). I, too, have a lot of beef with this setup. For whatever reason, ROW Samsung Galaxy S10s (G973F) are supported. Go figure ¯\\_ (ツ)_/¯

> In the case of the OnePlus 6T, only the T-Mobile version is ‘supported,’ when the unlocked version is the same in all other markets (including the US). I'm seeing two models of the OnePlus 6T: - 6T (A6013) This one is on the list of AT&T approved devices and most importantly has LTE bands 30 and 71 which are used in North America. [source](https://cacombos.com/device/A6013) - 6T (A6010) This one is made for the Chinese market and has the following LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28, 29, 32, 38, 39, 40, 41, 66. Notice that North American LTE bans 30 and 71 are missing. [source](https://cacombos.com/device/A6010) Are you aware of a different 6T model besides these two or are you saying there are 6T (A6013) that AT&T are rejecting from activating on their network?
