Can you use you mobile data at all? If not I would call your network provider, as they maybe the issue just there, maybe faulty sim? You getting calls I am guessing? Did you turn off mobile data?

What phone do you have? And network?

check my thread (post) on this exact issue - was this possibly after a software update to your phone?  In settings are you on Android 13 OneUI 5?
