iPhone 12 losing service

Received my iPhone 12 Pro on Friday. Activated it on Saturday. Sunday I drove for 10 mns and when I arrive to my destination I saw no reception bars and No Service. And in the middle of the screen in a grey box: Your iPhone is not Activated.


The only way to get the connection back was to toggle Airplane mode to ON then OFF.


The iPhone had the cellular mode to 5G Auto. I switched it to LTE to test. And it was the same.


So I resetted the network settings: same issue and I resetted the iPhone as a new iPhone and reinstalled everything from scratch (not from a saved backup): same issue.


I drove my car and found the exact location where the phone lost the network. If the phone lost the network it means I reach the end of the coverage area from a certain antenna. It looks like something happened with the phone when I reach a zone covered by a new antenna.


I called my operator and they told me that everything is good on their end and I have the right SIM card for a 5G device.


I called the Apple Tech Support and they remotely installed on my phone two profiles:

  • Baseband and Telephony Logging
  • CFNetwork Diagnostics


I was able to replicate the issue after talking to the Apple Tech and I was able to submit the report.


I pushed a little bit the research and I found on Reddit a lot of people talking about the same issue not only on Verizon (my carrier) but also on AT&T. Just use the title I typed and you will find the article.


I never had such issue with the 11pro.

My iPhone 12 Pro Max on Verizon (Orlando, Florida) had connectivity issues, dropped and failed calls. Spoke with Verizon support earlier today and they were able to help me resolve the issue:


  • Settings
  • Cellular
  • Cellular data options
  • Voice & Data - select > LTE


5G is very weak in Orlando and my iPhone used to disconnect because it was on > 5G AUTO (it was trying to connect to 5G network which was almost absent and then trying to switch back to LTE). If 5G is bad in your area, there is no point to try connecting to it. Just use LTE network only and you should have no issues with dropped calls (I hope it helps).

I have the new iPhone 12 pro max. I am sick of signal dropping out and having to reboot phone to get it back. Presumably under the Consumer Guarantees Act it would be deemed “not fit for purpose” and as such I can return for full refund? This phone is for business and I either can’t phone people at all, or the call is too patchy to understand. Super annoyed at paying so much for a sub standard service.

I read an article about this a few days ago, and today my wifi goes out at the house, and even though I have a strong LTE signal, I have absolutely no connectivity to data. I’ve tried the airplane mode toggle, reset network settings, restarting phone, and nothing works so far.


I’m using my wife’s hotspot to connect until they fix my wifi. Her phone is an iPhone 8 and it’s not having any problems. We also have an iPhone XR and there’s no problem there. And even a Samsung and there’s no problem with connectivity to data. Only my iPhone 12 Pro is experiencing problems.

I have been having similar issues with my iPhone XR since I updated it to iOS 14. I was in a new area that I used my iPhone for maps. Once I turned off my phone because I had arrived, when I turned it back on, my bars were 3 or 4, but I could not load the very map I was using to get back, without toggling the Airplane Mode button.

This has happened when I would drive 25 miles away from home and then return, the internet would not respond without me toggling the Airplane Mode button, at home!

I have the same exact issue and it’s beyond frustrating. Luckily, I have an iPhone 11 as my work phone so a lot of times I have to hang up, and call with my iPhone 11 which I have no issues with. It happens way too often with my 12 pro. In some severe cases, my phone completely loses service and I have to toggle my phone to airplane mode on/off and it automatically goes into 5G then. Really hoping they can fix this. I’m running iOS 14.2.1 btw. Please Apple, fix this issue!

Same here! (Iphone 12 pro unlocked)

i live in Brooklyn, NY and can no longer get cellular connection in my apartment most of the time. It just disappears. I use both verizon sim + att esim and only sometimes it comes back on at full strength. (Without me moving)

so it is not a carrier issue and for me it only started yesterday and Ive had my phone for 5 weeks.


restart / toggling airplane mode do not work. It slso seems to be independent of 4G/LTE/5G for me.


please apple, fix this asap!

Iphone 12 Mini

SAME PROBLEM

I switched over from Android but this is making me regret it. Never had this problem on any phone I have owned before. I know Apple knows about it. They also removed the battery percentage from the top right corner, only the icon is available, to force us to use the battery widget which takes up more space one than needed. But the signal lost is too much. It happens every few hours.


Gonna give it a try, if not forget it, will go back to Android where this wasnt an issue on a new phone and where they dont force you to use widgets.

Im having the same issues. I will be speaking to a client and all of sudden the client will say " Can you hear me, are you there" then I get a green circle call failed. Very unprofessional. This never happened at that location with my iPhone 10. I also had issues with no service at all in the same location where I had great service with the iPhone 10. What concerns me the most is missing an emergency call while driving and not realizing I have no service. I visited the Verizon store from which I bought the phones and they said it's a SIM card issue. I had the simm cards changed out on both phones and it made no difference. I would go back to the iPhone 10s but we traded them in. I was told to to toggle airplane mode to bring back service and that worked, but this fix is unacceptable. I turned off the 5G and that did not help. I have 2 iPhone 4s, 5s, 6s, always kept them as a backup, but I traded my 10s who knew?

Hello. I had the same problem for a new iPhone 12 mini in Italy with a SIM I was previously using with no problems in iPhone 8. The problem occurs randomly without moving from the house. The iPhone loose signal and I don’t realize until I try a call. The problem disappear rebooting. I have always very strong signal in my house . I sent the iPhone back and I’m waiting for a replace. The question is: if this is a general problem for all iPhone 12, should I give it back and have a refund instead of trying a new one that maybe had the same problem?

Understand... I’m an Apple lover myself, but it’s absurd to state that carriers EVERYWHERE across the globe need to change something that obviously works, just to prove an unintelligent theory that it’s not an issue with the NEW anomoly.


im excited about these AirPod Max and really want to buy them, but if I’m going to have to switch to Samsung, there would be no point.


please please, let Apple come correct and just make right their error, acknowledge it and fix/replace mine and other iPhone 12pro people angry with missing calls
