BlackBerry KeyOne
The BlackBerry KeyOne is a touchscreen-based Android smartphone with an integrated hardware keyboard that is manufactured by TCL Corporation under the brand name of BlackBerry Mobile.
At least it has a physical keyboard.
BBB100-1
Well, here we are. AT&T has implemented a whitelist excluding almost all BlackBerry devices from its network. Even the devices they used to sell. Can't roll back to the Key2. Can't even retreat to the Passport.
PRD 63116-036 is the only Keyone that will still function on the AT&T network.
At least it has a physical keyboard?

capacitive touch scrolling
The KeyOne's physical keyboard is also a capacitive surface that doubles as a touchpad. It works pretty well for large windows, except in post-68 versions of Firefox, where capacitive touch scrolling is inexplicably broken. Which is pretty much the only place I really wanted to use the feature. So, nevermind.
software updates
The last update from AT&T is build ACG696, which arrived on November 27, 2019. That's it, there won't be any more. This thing will always be stuck on Android 8.1.0.
2022.07.02 Update: For some reason earlier today AT&T attempted to push this last update to my phone. The installer crashed at 85% three times in a row, and then bricked my phone.
2022.07.03 Update: I was able to run a direct loader on an old (32-bit) Macbook and restore to the latest AT&T image.
