“No SIM installed or “SIM Failure” messages

Hi DSTDean,

Thanks for responding to my post. I don’t know anything about iPads except they run their own OS which is different from the iOS that runs iPhones. The problem I’m having has only started since I began running Public Beta versions of iOS 15 which is the new iPhone OS that will be released in a few weeks. There may be some connection between what is happening with your wife’s iPad and my iPhone 12 Pro Max but I really can’t say for sure. I’ll be upgrading to the iPhone 13 Pro Max for sure and hopefully this really weird behaviour won’t still be happening with a new IPhone. I’ll be using the SIM from my 12 Pro Max in my new 13 Pro Max and if the problem happens still I’ll be asking my cell company for a new SIM! I hope your wife soon solves what is happening with her iPad, the problem I’m having is driving me crazy… Regards, Thorvald (aka dj.faeridust) :-))

The problem has now gone away because I’m using the eSIM on my new iPhone 13 Pro Max 256 GB (Sierra Blue). The problem with a no SIM installed message frequently appearing on the screen was happening on an iPhone 12 Pro Max (which I loved…). My cell provider couldn’t explain the problem with my previous iPhone and it was they suggested using the eSIM when I received my 13 Pro Max. Setting up the eSIM on my new 13 Pro Max couldn’t have been easier! I’d definitely recommend anyone with an iPhone that comes with eSIM capability to consider switching over to it (it looks like one day all cellphones will only come with eSIMS, probably dual eSIMS…). Peace & Love, Thorvald
