iPhone 12 Pro - Call Failed - Verizon

I've had my new 12 Pro for 1 day and cannot make or receive calls. Receive "call failed" message. Can receive and make texts as well as email. Verizon says it is related to 5G outage but it doesn't make sense since LTE and WiFi calling don't work. Anyone having similar issues?

iPhone 12 Pro, iOS 14

I wanted to update everyone who has been following these post. Verizon was nice enough to send me a new iPhone (12 Pro.)

When I got it today, all I did was activate the cell service over wifi. I did not put any apps or personal data on the phone. It came with software version 14.2.1 I did not update it to 14.3. I turned off automatic updates. Which also in on by default. I made sure Wifi calling was on. (by default its on)


I started to call. Did not drop a single call. It was happening on my older (2) 12pro's every 3 -5 min. I haven't mad 100's of calls yet. But is seems the problem is not there. So it seems to be the update process. Not the update or the Version. My old phones worked fine. My first phone came with a version less then 14.2.1. I updated it to 14.2.1 as soon as I did Wifi calling started to drop. My second came with 14.2.1 it worked fine. As soon as I updated it to 14.3 it started to drop calls.

This phone (which is my third) came with 14.2.1 so far it works fine. I will not update it to 14.3


So again, I think it is the update process that is causing Wifi calling to break. As I make more calls, I will update everyone.

Our situation is the opposite; I have a 12ProMax which has the "Call Failed and Wi-Fi Calling" issue and my partner has a 12Pro with never any calling issues since the beginning.


I must say though that I haven't had any issues lately but haven't been paying close attention to anything cause I've been busy but I am currently on iOS 14.4.


I'm going to start paying attention again and report back.

I agree. I’ve been having other issues with phone calls that are phone or iOS related. If I am successful in making or answering phone calls, I can’t hang up. When I pull the phone away from my face the phone screen is black. I have to fumble around to find the phone app and when I do there’s a green button not a red one (to hang up) I recently saw that the time in the upper left hand side is in a green oval and apparently you have to touch that to bring the phone display back. Not very intuitive.

Pressing the Side button will hang up the call.


If the phone screen is still black when you take it away from your face most likely you have a case that is partially blocking the proximity detector that turns off the screen when you hold the phone to your face so your fact doesn’t trigger any buttons.


Not very intuitive.


It IS described in the manual, but who reads manuals? Also in this KB article→Status icons and symbols on your iPhone - Apple Support near the bottom:
