About two months ago my phone was saying SIM card not working I went down and got a new SIM card that started working now fast-forward about two months
last night my phone was saying no SIM card I would take the SIM card out put it back in it wouldn’t register the D register now it won’t register with my other SIM card either what is the problem
Try and see if you can get an eSim instead. I had same issue and after 3 or 4 times my service provider suggested eSim. Only problem is an eSim is very easy to remove, so if you don't remove it your good. If you do, it can replaced with another.
