Hey there!
My iPhone 13 Pro began having SIM card issues on Friday evening (6/28/24). The issue resolved itself within a minute or two when it would occur.
The next day, I received a SIM Card failure message. My phone is in SOS Only mode, and I cannot receive a text message to verify my account, in order to switch to my eSIM card. Verizon Support hasn't been much of a help, in large part to not being able to verify via text message. Help!
