ive got a physical sim and an eSim, different numbers, same carrier (one professional one, one personal one). Both SIMs were working fine, and then all of the sudden stopped working simultaneously. The physical sim works fine in my wife’s phone, so we have ruled out having a bad sim.
Restoring via my Mac fixed it for about an hour before it stopped working again.
I don’t think it’s a hardware issue as it wouldn’t have worked after the restore in that case.
ive been in touch with apple support who are also none the wiser. Starting to think it may be an issue in 14.4?
I’m on an iPhone 11 by the way.
