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).

“....This has nothing to do with an app installed on the phone.....”

  • Yes, I just said that to Dominic1243. I never claimed it had.


“...Since when can you run antivirus on iOS?!...”

  • OK my bad collective noun, should have said there is no place for mobile security apps on iphone, even though many claim also to be antivirus.


”...VPN definitely has a place on a device.....”

  • your choice but choose wisely

I have iPhone 12 pro max. And I started with T-Mobile service. iPhone kept dropping service outright or slowing down to minimal bars. Switched to Verizon yesterday and my iPhone went from bad to even worse. I have to continually reboot iPhone. And I must continually toggle airplane mode. After 40 network resets, service still dropping to LTE or worse. Got a Genius Bar appointment tomorrow. Will see what happens. I’m really dissatisfied in Apple again. I thought the 11 max was a horrendous iPhone, now I’ve seen everything

Friends, Am I on the wrong discussion? As mentioned in a previous post, I’m retired and not in the same need as some of you who are dropping business calls. My situation is this: I have not received a call since last Wednesday although I know people have tried. The call goes immediately to VM and here’s a twist, There is no record of the call in the “Recent” folder.


So if I make a call the phone drops the call, and I’m not getting incoming calls. At the moment it’s a $1000 paperweight.


Reading the comments, many of you have spent untold frustrating hours with your both Apple and your carrier’s tech support. Observing the fruitlessness of this, I have not made any attempts to contact tech support.


In a way, this is a true “Catch 22” situation. I can’t talk to tech support because the phone will drop the call!


Any suggestions will be welcomed.

I’m sorry that others are also having this iPhone 12 loss-of-signal problem. But at least now I know that it’s not my imagination. I live in a Verizon only coverage area, that is just LTE. But like others, turning the phone off and back on (or airplane mode is easier) will always bring back cell service. It is funny that when I talk to AppleCare tech support, they act like they’ve never heard of the problem before in their life! You gotta love Plausible Deniability!

Gosh, Im having the same issue when I'm out and about. It seems like its trying to switch itself from 5g then to LTE and in the process I get nothing. It's been happening since I activated my 12pro. I have to toggle on and off my airplane mode as well to get it to catch up. Happened to me at the worst moment while I was trying to connect to my home doorbell camera in order to receive a package. smh I feel your pain
