Got a used mint condition AW 4 steel Cellular for 200 bucks. Besides software problems I’m not missing anything

I sadly can’t use cellular on my cellular aw since apple doesn’t allow to have different contracts for the phone and aw :/ The moment I put a different sim in the iphone the sim on the aw gets disabled

Sleep tracking is kinda buggy, apparently you need to set a fixed sleep schedule and it’s only tracking inside that scheduled. when I didn’t set one up but activated sleep mode manually it didn’t track my sleep. I’m super disappointed at how bad the setup is :/
