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 a 2 week old IPhone 12. I am loosing service constantly, which makes it really difficult to deal with since I HAVE CLIENTS.


How will you fix this?, I am in Costa Rica. Movistar already changed the SIM card, "restarted my line/service", and offered me a ton of excuses not to replace this phone. So, my question is Are you guys at Apple actually doing anything to fix this? Because probably I will not get anything out of a new phone since they're all malfunctioning.


I already gave up my XR to my daughter in hopes that the new phone might work better.


Well, it doesn't. At all.


Fix this, your devices aren't cheap and somebody has to do something.

same here I had a few of my comments deleted. It’s not right they’re just trying to hide the problem. Should be offering refunds I’d take my old iPhone 7 over this heavy mini wifi ipad. And I even recall telling the wife no no I’m gonna get the more expensive one so it has no issues because it’s for work. Also I even bought this direct from Apple, thinking o those will be the really good ones. WRONG

IPhone 12 does not work. It looses signal and service on its own constantly. Please resolve.


I will put that first paragraph on every reply I post.


I need you guys at APPLE to please treat us as you have, in my case, for more than 16 years. WITH RESPECT.


Help us find an answer, gives old phones that work. I do not mind at all as long as they work.


I have family, friends and clients who depend on my availability to communicate as soon as possible.


What are these forums for if not to help those who bring bread to your table.


Let me do the same. I need an Apple phone that works.

I continue to have issues with my iPhone 12 mini. In the last week I have people telling me they are calling me but my phone does not ring. These people are not in my contacts and I have my call blocker turned off. So I should be receiving their phone calls, yes?

The same callers instead texted me and that arrived without any issues. Not receiving phone calls on a phone is just unacceptable. Anybody else having the same issue? By the way, I am using the latest & greatest IOS, 14.6

I'm so disgusted with this phone and the constant issues with phone calls/reception, etc.
