I have an iphone 13 and it randomly went into SOS Only mode and I am unable to make or receive calls or texts. I tried resetting the network settings and several other troubleshooting suggestions and nothing is working. The only thing occurring simultaneously with this has been pop up saying "No SIM card detected." When I go to cellular data under settings the only option is "set up cellular." When I click on that it only offers options to "transfer from a nearby phone" or "use QR code." Any help is greatly appreciated as I am currently unable to work.
