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

Team… is there any resolution for call failed ??? Since ios 18 I am facing this issue a do you want your users to switch??? From ios to Android??? Need urgent assistance.

I had a same issue. I could not get incoming callings. Outgoing call is no issue.(FaceTime& text message are no issue. I can get callings via FaceTime)

I went to Verizon, and they replaced a new Sim. Then it works.

my phone is iPhone 13 Pro.

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.

Is anyone also experiencing inability to reply to SMS texts since updating to the latest iOS 18? This accompanied with not receiving calls has rendered my iPhone 13 useless. I only receive voicemails and iMessage texts.

Hi… issue is not with SIM … how come the SIM which is working fine before ios 18 and not working after ios 18 update . Not possible.. issue with device only . They have sent bugs intentionally with the update for iPhone 13 so that users buy new iPhones.

Hi… Actually Apple is least bothered about this… I have called them and chat with them so many times. Also they have gone through many tests . But they are unable to resolve .

can anyone help and share any details of Apple support. So that I can contact higher authorities?? Please share. Thanks

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!

Hi,

i am facing the same issue. Is there any resolution?

Restart the phone and try. It worked for me

No issue from SIM and carrier side . Apple had intentionally sent bugs update for iPhone 13, so that users bury new iPhones . Pathetic services

Hi… I have restarted the phone … RESET THE PHONE, Update the software also . But all in Vain . Apple had intentionally doing this for old iPhones

I am not sure route cause clearly, but it seems that after updating the OS, the phone overheats while charging, and this likely caused damage to the SIM card.

I’m also experiencing the same issue. It’s seems like I won’t receive calls if I’m in an app or active on my phone sine update. There’s not even a notification of a missed call or vm.

Having same issue but my sms and data is working. I am unable to receive and make a call. Device iPhone 11 Pro 18.0.1
