No SIM message on and off all day

My iPhone13 Mini keeps showing NO SIM message. I lose cell service, turns to SOS, then cell service comes back. Rinse and repeat all day. I've tried all methods ( turn off and on, remove SIM card and put back in, carrier on and off etc.)

Is this a carrier problem exclusively or is it an iPhone problem

Thanks.

iPhone 13 mini, iOS 16

If you get an alert that says Invalid SIM or No SIM Card installed, follow the steps in this support article: --> If you see 'invalid SIM' or 'no SIM' on your iPhone or iPad - Apple Support


You could ask your carrier to send you a new SIM card.
