I have also encountered cellular network issues on iPhone 15 Pro. After updating to version 17.6 at midnight, I noticed that my phone was disconnected from all cellular networks in the morning. Instead of displaying cellular signal strength icons, it shows a 'No Service' message. My phone is only 1 month old and the only change has been the update.
iPhone 15 Pro, iOS 17
I figured out the issue, both my eSIM and physical SIM cards were damaged. To fix this, I had to remove both SIM cards and reactivate them. Just deleting only the eSIM card and reactivating it didn't work.
Unfortunately, I couldn't reuse the damaged physical SIM card and now need to replace it with a new one. The physical SIM card was for a roaming network, and obtaining a replacement will require me to travel back to my home country. This replacement is estimated to cost around $400. This is an important issue for me because all my OTP and login verifications come to that SIM card.
I believe the software update is the only reason for this problem. Thank you APPLE for putting me in this situation!
Same issue after installing iOS 17.6 update last night, different error showing on my iPhone 12S startup screen: "SOS".
No phone service, texting and other functions appear (so far) to work on iPhone 12S. This Apple Support article procedure If you see SOS, No Service, or Searching on your iPhone or iPad - Apple Support had no effect and provided no information to forward to my carrier (Veri...). I verified my acct, other iPhones 12S without iOS 17.6 using my acct function normally.
I reached out to Apple and followed the troubleshooting steps below, but the issue still persists:
1. Rebooted the phone multiple times and switched Airplane mode on and off.
2. Performed a network reset.
3. Reinserted the physical SIM card and attempted to reinstall the eSIM (unsuccessful in reactivating the eSIM).
4. Finally, did a complete factory reset of the phone, wiping out all the data.
Unfortunately, none of these steps resolved the issue. I am still awaiting a solution.
