Yeah, I recently started trying their “network pass” and was quite happy that I got coverage (unlike my current carrier.) Tried creating an account to go with it, now I’m locked out for whatever reason, and my username is “null”.
I guess I’ll just use the eSIM they gave me until they cut off my access.
Moral of the story: ~~T-Mobile~~ mobile carriers suck

Gives a surprisingly good Bedrock experience on Linux and macOS. Just needs you to own the game on the Google Play Store.
