No SIM card installed keeps popping up

I eventually found an easy way to resolve this:

simply put the iPad into Airplane mode, but then activate Wifi on it's own.

job done.

Telling Siri to "turn off mobile data" solved it for me.

This is the suggestion that worked for me. Thanks.

You should be able to use these devices to their fullest capabilities. I have a cellular account that I pay for and should be able to use. Turning off functions is merely placing a bandage over the gaping wounds. None of the suggestions stated above work. Apple needs to perform drastic testing of upgrades and devices and then do it all over again before these things are released tocnsumers. I use Apple wifi phones at work for emergency contact between staff. These phones have also been completely unreliable.

I left Android system to give Apple a second chance. and regret it every day. The problems they have with upgrades and the support they provide are horribly inadequate.

At my first opportunity I will be going back to Android.

No SIM card on my iPad mini keeps popping up

Anyone tried to turn off Wi-Fi Assist ? I just did and it stops

Hope it works.

thanks

I have had this same problem for a while in my iPad with Retina display. Looking at the device console in Apple configurator 2 during the popup, is shows some errors about baseband reset and resetting SIM information. I'm not sure if this is a hardware problem or problem in device drivers, but very annoying indeed.
