No SIM error on iPad but it does not have a removable SIM - What do I do?
I have an iPad Pro 9.7 that I have been using for 3+ years. In the past couple of months the cellular connection would stop working at times, then start working again. It is still doing that more frequently now, but as the cellular stops working it flashes up on screen a "No SIM" error. But the SIM tray is empty as it has an internal SIM. What do I do to get this working correctly? I have done everything that has been recommended by Apple and AT&T via their troubleshooting sites. Updated the OS, Updated the Carrier Settings, Turned the device off and back on (which this will sometimes allow it to start working, but within a few minutes I get the No SIM error message again). It also recommends trying a new SIM, but it is built in so not sure what to do there. Can AT&T send me a new SIM?
