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).

SAME HERE!!!! Im literally going to have to take a loss to go back to an iPhone 11 because of this garbage. I've missed so many business calls and text because of this. I have to now remember to turn on and off airplane mode every time I enter a building at my job. If I don't do that my phone has ZERO service and is deactivated. ALSO, no WIFI CALLING IS USELESS.

I wish I would have kept my 11 pro and skipped this... I've always kinda blindly trusted upgrading every year, but after this debacle, I will forever be skeptical. This to me is one of the worst screw ups Apple has made. The Reddit, ATT, VZW, and Apple forums are full of this same complaint and its a big one! NO SERVICE and DEACTIVATED phones are not small issues and should be addressed immediately.

Good for you... you’ve added zero to this thread. I promise I’ve looked into this more then you, because I’m actually trying to find a fix for the issue OF NOT HAVING A FULLY FUNCTIONING OR RELIABLE PHONE and yes, there’s enough of a broad issue for this to be officially addressed by Apple. The world is a bigger place then you individually never dropping a call. This is a worldwide issue, not just an ATT or Verizon issue. I’m with VZW btw with a new sim and I know multiples that have had the phones replaced and still have the issue.

Today I called Verizon to check out the non working phones. They said that they had no clue about this issue. They will send me a new SIM card. Will this work??? I don’t think so. I believe is more an Apple problem that they do not want to take care of it. It is frustrating to not be able to use your phone and not to be able to take it to Apple to fix it because they don’t have appointments in weeks!!!

So is this another AntennaGate? 48 pages of the same issue on just this forum? It sure seems pretty wide spread to me. I can't open a ticket because mine is so sporadic. I've been trying to track times and dates and I put in feedback but that's apparently not getting Apple's attention and neither do all the calls to support. How do we get their attention on this issue.

i'm having the same problem with my iphone 12 on t-mobile.

  • cell signal would drop to one bar and sometimes no bars in places where my old iphone 8 plus had full bars (namely in my home).
  • people are saying calls go straight to voicemail when they call me
  • i would notice voicemails when my phone never rang
  • sometimes when my phone loses all signal, it would never come back and the only way for me to regain signal is to restart they phone (toggling airplane mode doesn't work).

hoping apple fixes these problems soon

Amazing that so many of us continue to experience these issues. Earlier today I noticed that once again I lost my signal strength while inside my home. That should not be happening. When my carrier was AT&T and my iPhone was the 7, signal strength. never was a concern, especially at home.

I read that the latest IOS updates do not seem to recognize this issue so I guess expecting a fix with an update is out of the question.
