iPhone 12 Pro - Call Failed - Verizon

What is strange is that my wife has an 12ProMax. 14.2.1 (which it came with) no problems at all. Only difference, she has never updated her phone to any new software update. And my phone worked fine until I updated it to 14.2.1. I got my phone a week before hers. Thus my phone came with 14.2 so I updated it to 14.2.1 same as hers. But she has no issue.

This is a good point. Maybe it’s a Verizon issue then?

That’s a strong possibility, but I don’t think there’s enough evidence to say definitely.

Another thing to try: Wi-Fi calling, on or off? Some users have said turning it off helps.

If your new phone is 5G. You would need a 5G sim. So you should have gotten a new one. My wife has a 12Pro max for 3 weeks. Never had a problem. She never did any upgrade of software.

my 12Pro worked great. Until I did an upgrade. The same thing happen to me with two different phones. So I asked my wife not to upgrade. She has not lost a call on Wifi calling.

I purchased an unlocked 12ProMax and used my 4G SIM from my 11ProMax for a few weeks before ordering a 5G SIM card and upgrading my plan.

I was having "Call Failed" issues immediately; turning Wi-Fi Calling off or Airplane Mode on/off after a failed call were the only fix. I initially thought the 5G SIM would be the fix but the problem returned after a few days.

So far I believe that it has something to do with the process of upgrading the software. I have had two phones that came with two different versions of software.

they both worked until I upgraded the software. Even if you restore the software. Make the phone as new out of the box (which now loads the upgraded software) even if it is different then what came with the phone. It does not work.

so I think in the process of upgrade something is changed and does not reset no matter what you try.

that is what I see.

I understand the frustration. There is a problem with the iPhone 12 when the carrier is Verizon. Apple and Verizon have to work together to resolve the problem, and I’m sure they are working on it. But until they do what has been posted are imperfect workarounds.

What you can do, if you haven’t already, is update to iOS 14.3, and contact Apple support using the link at the top of this page so they can log your problem along with others to help them establish the extent of the problem and find the root cause.

I set up my replacement 12ProMax last night. I did my restore from backup attached to my Mac instead of over the air. Sorry to say but I was on 3 work phone calls this morning and all 3 dropped "Call Failed" about 1-2 minutes into our conversations. This was with Wi-Fi Calling on.

Needless to say, getting a new phone has not solved this issue. To finish my remaining work calls for the day, I turned off Wi-Fi (not Wi-Fi Calling) and made all calls through cellular and all were fine.

I'm on a different network in my country and I'm having Called Failed issues intermittently with iphone 12 pro max while another family member have Called Failed issues on iphone 12 pro after upgrading our phones.

On latest IOS14.3, turned of wifi calling, changed 5G to 4G, nothing works. Apple support told me to contact operator while operator replied that could be due to iphone 12 signal receiver weaker. Going to book another trip to Genius bar.

Mine isn’t a Pro, just a 12. They tell you to go to airplane mode and turn it on for 5 seconds then turn it off. It worked for a day then I stopped getting calls again.

my wife and I shut WiFi calling off over a week ago. She’s only dropped one call since.

I would give it back before your 14 day return period is up. I do not think they will fix WIFI calling soon.

they just do not want to hear it. And they do not tell the truth.

I’m on version and am constantly having this issue as well ever since upgrading to the 12 pro. Verizon has no solution and I believe it’s the phone as my 11 pro and my wife’s 11 pro max do not have this problem.

No issues with my 2 iPhone 12 Pro Max devices on Verizon (not sure if this is only happening to those using the iPhone 12 Pro). I remember having similar issues with my 11 Pro Max last year and it took numerous calls with Verizon before a tech figured out it was a provision issue. Not saying that’s any of y’all issue. I just know that Verizon has often said an issue wasn’t on their end when it was.

I think it time to contact apple technology team for help and resolve the issue. It is after lot of iphone 12 pro owners reported the problem of with the phone calls and sometimes caused by careless attitude to upgrading the software, I have noticed causing irritating issues. So much so time to time I am not inclined to upgrade. Good news is after some time apple engineerfigure out how to fix the problem their upgrade caused it.

I am loyal customer of apple for the last 15 years but.....?

I have the same issue and its infuriating. This phone cost over $1,000 and it cannot make 1-800 calls or even call Verizon to 611. I have to use another phone or Google Voice to call customer service lines.

At the beginning I had the issue others were describing and the Verizon Store said it was the SIM card that was failing. I can now call regular numbers, but 1-800 and 611 are a no go.

There is something wrong with these phones or with 5G networks in general. Is Apple going to provide any guidance on a fix because it's unacceptable to sell people $1,000 phones that cant make or receive calls.
