iPhone 12 Pro - Call Failed - Verizon

Dr Google says to toggle airplane mode on and off. That’s a software problem

I was told by Dr. Google to go into settings and toggle on and off the airplane mode and it seem to work for me but it’s still a software issue

Apple replaced my phone but I had only had it 2 weeks. I have not had the problem since then.

I just did a trial with a new carrier. The exact same problem exists. So this is not a carrier issue. This is an Apple issue. I am going to ask for a phone replacement.

I have had the exact same issue. Purchased iPhone 12 pro. Someone tries to call me it will say my number is not in service. I try to call someone and it will say called failed. I then have to turn airplane mode on and back off and it will start working again but there is no way for me to know if it is or isn’t working since it says I still have service. Just have to randomly try calling someone throughout the day to know if I have to turn airplane mode on and off again. Very frustrating.

turning airplane mode on and off is the only thing that seems to work out of all the stuff I have tried but that is not a fix. Just a temporary solution.

I'm having a similar issue on my iPhone 12 Pro Max, which I've had for over two weeks. I can receive calls but when I attempt to make a call, I always get "Call Failed". The only way to fix it is to turn off/on Airplane mode for a few seconds and have iPhone search for Verizon service again. Once that's done I'm able to make my call.

I've also heard but not confirmed, that this issue might be related to having "Wi-Fi Calling" setting turned on as the main issue causing this problem. In my situation, call failures still occurred when "Wi-Fi Calling" setting was turned off.

At this point, I'm not sure whether this is a hardware issue, software issue, or a Verizon issue.

I have been with tMobile for 5 years. Just 2 days ago upgraded to 12 pro max. Can’t call out or in. Followed all reset, power off, os update, etc. still not calling in or out. Same exact issue with wife’s new 12 pro max.

Did you get a new SIM? The 12 series requires a different SIM for 5G coverage.

I have had reports of the same; not being heard and on a few occasions was told I sounded robotic, LOL.

I have Wi-Fi Calling turned off in Settings for now which has helped. I am also still waiting for a new SIM card from Verizon which they wanted me to try and see if it helps fix the issue.

Just posting a follow-up. Looks like replacing my SIM card was what has solved my Call Failed issues. I've not had any dropped calls at all since installing my new SIM card from Verizon.

I realize this may not work for everyone but it's worth a try if you are still troubleshooting.

Same here. I also don’t have issues when airplane mode is on and wifi calling is on. So somehow the cellular service interferes with the call.

That is very interesting. The network is supposed to switch between Wi-Fi and LTE seamlessly if the signal for Wi-Fi is marginal; that may not be working properly. Go to Settings/Cellular; what do you have for the Wi-Fi Assist setting (near the bottom of the listing)? Does changing it to whatever it isn’t set to help the problem?

On my phone with AT&T it does work as intended; if I move away from my Wi-Fi network while on a call it switches to LTE without interruption. But I also don’t have a 12.

Apple support asked me to restore my phone via computer and not download any of my apps and email accounts and such, which I did.

so with nothing added and WIFI calling on. Still dropped calls using WIFI calling.

I am going to request a new phone. When it comes I will connect to my iTunes account to setup my phone. I will not connect it to my computer. I will not update it the the current software.

I truly believe that the process of upgrade is what is the problem.

my wife has a iPhone 12Pro Max. Has never upgraded the software and only got her info over the air via iTunes account. She has never had a problem. Same house same WiFi as I. She never updated. I did on two different phone which both worked before I updated.

The only advise I can offer. In the short term 2 options. Turn off Wifi calling, but leave on Wifi. If you have poor cellar service and you are using Verizon. You can call Verizon and request a Wifi extender. once you set it up you will dial #48 only once it will then allow you to make calls over Wifi without using Wifi call turned on via your phone.

I am not really sure they know.

Well, if you mean Apple or Verizon, they don’t know unless users contact them and tell them. I hope you have done so. Here are several ways to contact Apple:

• https://apple.com/feedback
• Click the Contact Support link at the top of this page
• Use the Apple Support app on your phone
• DM @AppleSupport on Twitter
• Call Apple support using your regional phone number: Contact Apple for support and service - Apple Support

Have you updated to 14.4? My WiFi calling problem seem to gone away after the update. Still testing.

It’s about as acceptable as selling a device without a plug to charge it. I had the same problem with my iPhone 12 but I had to turn on my airplane mode two days in a row and it seems to be working just fine now. But I was without my phone until I finally got it working. Apple support took down my post about selling a device without including a plug to charge it. Someone told me to use an old one. I don’t buy a phone every time a new one comes out so I don’t have an old one that works with this phone. And what’s the solution for someone that’s buying Apple for the first time?!?
