Do most smart TVs still allow performing updates via USB? I have an older LG TV which does this.

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
