On iPhone, Sim cards contain nothing more than your telephone number and have nothing to do with keeping the operating system up to date.


If you go to Settings > General > About > Version > If your phone is on iOS 15.0.1, you are up to date. If you version is lower, you are not up to date.

Thank you so much! I am ready to update to iOS 15 I just was unsure if the bugs was worked out of it. I updated my service and I got a new SIM card and new phone number but I looked my trust certificate up and it is not showing to be the correct one. I tried to save my voicemail and it wouldn’t save. I have 2 imei for some reason I hope I can get it figured out
