Unable to receive or make calls from iPhone post iOS 18 update

Is anyone else having issues with calls failing/not being able to receive calls after iOS 18 update? It starts working again temporarily after switching phone off and on again, but within a few hours, I can't make or receive calls again until I restart the phone. This started immediately after updating to iOS 18.

Hello,


I was able to fix this over the weekend. In my case (iPhone 13; iOS 18.0.1):

-Incoming calls (excluding FaceTime) would not ring and go straight to Voicemail. This issue also left no missed call notification. I would only get Voicemails

-SMS Texts would fail to send (not including iMessage)


Solution: My carrier reset my line connection on their end (AT&T 611) and calls started coming in. After, I turned off RCS Messages and the SMS Texting started working again.


RCS: Settings > Messages > Scroll down to RCS > Toggle Off


Hope this helps!

wasted 9 hours on the phone with Apple, Verizon and Norton as with update to 18.5 day before yesterday can no longer receive calls from businesses. It turns out it is no longer allowed to have protections from other than Apple is blocked.

Time to ditch Apple and get a flip phone - Apple complicit in targeting Americans and complicit in spying on Americans.


Just read article about what happened in the UK: Tech giant is removing its Advanced Data Protection system, which encrypts user files uploaded to the cloud


Is Apple on board for this now in US - could be starting with this update and inability to turn off AI access to camera and microphone...spying and giving access here now too?
