No Sim detected

[Onker1]

I have been getting this message frequently the last couple of days on my 11 pro max. I updated to 13.4 when it became available. If I restart the phone it will work for awhile. I’m on ATT. Any ideas? Is it a bad SIM card? Anyone else having this issue? Thanks for any help or suggestions you send my way!

It’s possible you have a defective SIM, but I can’t say for certain. Have you tried removing it, cleaning it off and then re-inserting it?

Have you tried removing it, then reinserting it back?

Something similar happened to me when I went from my 7 Plus to my Max. I had to get a new Verizon SIM card.

Thanks for the suggestions. I have taken it out and put it in another phone actually. That phone worked fine and this morning I put it back in my iPhone and it I has not given me the no SIM message yet...crossing my fingers!
