sim card not installed

My new iphone 13 routinely will say "Sim Card Not Installed" and I lose service. The way I fixed this last time was to do the latest software updates, but don't have that option now. Is the new phone itself?

iPhone 13, iOS 15

I'm having the same problem. New iPhone. From day 1 I'm experiencing "Sim Card Not Installed" issues which comes and goes randomly. In some cases my phone was at rest on the table and my screen turned on to show "Sim Card Not Installed" then moment later the SIM card worked and that repeated few times. I've removed my SIM card and cleaned the contact surface to ensure there is no oxidation on the SIM card. I've popped it back in, it worked for some time and soon after I got the same message. I have a simple dumb phone, which never had problem using this SIM card.


I read suggestions to switch on and off the airplane mode / restart phone / re-insert the SIM card.. but those are not proper solutions.
