hmmmmm, now that is interesting. However, my luck, I'd get flagged as not abiding by some agreed to, by use, contract/ToS for using a tablet SIM in a non-tablet device as defined by some lawyer to avoid this very thing.
Yeah it’s not supposed to be allowed. I’ve been told by a T-Mobile employee on Reddit and discord (big community for T-Mobile lol) that they aren’t going to do anything usually.
My cousin in HS runs her family’s tablet SIM card in an old iPhone and runs ads to make a dollar a day. They end up using close to 100 GB a month.
The other carriers could be stricter.
Maybe something to check up on a bit. But not a big deal regardlsss hah.
