Receiving the notification “SIM Failure” several times a day on iPhone 15 Pro Max

I have an iPhone 15 pro max and I kept receiving the notification “SIM Failure” several times a day for several weeks. I finally took my phone to my service carrier thinking they should be able to replace the eSIM. Nothing worked and they tried a factory reset of my phone. Now my iPhone isn’t able to add cellular service at all (and no place to add an eSIM either). Anyone else encountered this issue? Help please?

I totally get where you’re coming from and I can empathize with your frustration. Here’s a suggestion that might help. It’s similar to what I went through last year. After trying everything my carrier suggested, I realized it wasn’t the carrier’s fault. It turned out there was something wrong with my Apple iPhone itself. I took it to Apple for a diagnostic, and they found some hardware issues. So, they gave me a brand-new iPhone of the same model. I think this might be the issue with your phone too. I hope this helps you out! Best of luck!
