iOS 17.3 cellular issues

Hi. I’m on an iPhone 15 updated to iOS 17.3 and I’m having cellular issues from time to time. I Cannot make/receive phone calls nor send/receive text messages.


The problem occurs intermittently, sometimes airplane mode on and off or restarting the phone fixes it for some time. And I already reset network settings and got the settings for iPhone from my network connection provider.


There are no issues with my service provider as swapping my SIM card into another mobile phone works fine as I don’t have any cellular network issues then.



I have to stress that these problems started since the 17.2.1 iOS update, however it’s occurring less than on 17.2.1 .


Is there anyone else who’s having similar issues ?

iPhone 15

My carrier is T Mobile and today finally I s/w a supervisor that admitted they are fielding lots of similar calls in some areas . I live in SF . I took the phone into Apple and they said the hardware was good, there were no issues, Back to T mobile , the supervisor told me to update to the latest IOS 17.3 that it would remedy the problem I am about to do that
