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.

I am surprised this situation has not been addressed properly by the carriers or Apple. They each seem to be ignoring and hoping the problem will go away. Which it will NOT!

Imagine paying hard earned money for a product that only works, "part-time"? Clearly that would be frustrating for all consumers. Nobody likes to waste money.

I was already given a replacement phone and SIM cards and guess what-neither of them corrected the issue. Once again today I have 1 bar, 1 bar of signal strength at home. My phone is resting on the table and only has 1 bar. No reason for that. Unacceptable. Then when I left the house for a short drive, I lost all signal strength for about 4 minutes, had to go in and out of airplane mode for the signal strength to reset. UNACCEPTABLE!

Thanks for the first answer from months that seems to give an answer to this huge problem that’s affecting iPhone 12 all over the world. My question is: does Apple think that carriers in all world countries must act on their towers (I’m in Italy)? Or should Apple phone understand that the towers doesn’t recognize the new band signal and switch to the oldest one?

If your explication is correct, it is also the proof that this is Apple problem.

From experience it does not make a difference. Same issue exist. I thought it resolved but after driving to an area where towers switch it goes back to no service so it appears to be That issue between tower switch to different tech as one is 5G lte the other only shows 5G lte or if I hit my home wifi all 3 show no service for a time. Eventually it will finally come on after 20 min or so or airplane on and off does it as well.

How did you get a full refund? I have all these same issues with my blue 12 pro. my husband has the grey and doesnt have issues so i know its the phone. Im positive its the antenna because when i have no case on the phone it works loads better. The minute i put my case on, no service half the time. And ive bought 4 different cases. So i know its not that.

I haven't called. Honestly i had just chalked it up to bad luck and i've been home all this time so using my wifi. Now i'm back to work and I obviously notice it how bad it is now because my job doesn't give us wifi. My husband says we should wipe the phone like new. No restore. But from what i've read that doesn't even work right? I am going to call support later. Have my hands full with a new baby so hard to find the time. Still, i've had iphones for 10yrs, this is the first one that's given me any problems.

A couple months ago I contacted Apple, my case was elevated and I received 2 phone calls from an Apple rep show originally showed great interest in my iPhone trouble. After those 2 calls and several emails it was silence. I was "ghosted". Since then no phone call, no follow up email. Just forgotten about and that tells me that person or team has no care in the world and no interest in customer loyalty. Am I wrong?


Mar 3, 2021 3:56 PM in response to Dogcow-Moof

Thanks for the feedback. You have much better manners compared to that Apple "rep" who ghosted me. You see they promised more follow up after I sent them the diagnostics. So based on what they promised that is why I am disappointed and unhappy with the service. Unfair to customers to be promised continued contact and that follow through never does happen. Am I right?

I'll agree with you.


We're not asking for much. I have a feeling the Apple rep went MIA on you is because they don't have a good answer to the problem, nor do they know of a solution.


Whether it's an Apple issue or not, a simple statement like this can go a long way to putting people's minds at ease: "We are aware of the service issues affecting some iPhone 12 users. We are working with our carrier partners on a fix, but do not have an ETA at this time."


It's called customer service. I pay a company money, and I expect the company to support the product I purchased. Not rocket science.

I have an iphone SE (2020) and have been having this problem since I got it. It isn't every day, but it goes out in the middle of a call and throws up a No Service error. This is so whether I am on Wi-Fi calling (which I usually am) or cellular. It recovers after a few minutes on its own, and nothing I can do seems to speed it up. It's good again until the next time it cuts out. Spoke with Verizon and did all the troubleshooting steps. Nothing ever fixed it. They told me that iphones were having this problem a lot. Clearly this is a hardware/software issue and Apple needs to fix it. It seems to happen more on long calls than short ones, although it's happened on both types. Possibly that's just probability though.

My wife was constantly having this issue when she was at work since picking her new iphone. A couple weeks ago Verizon did some work on the cell towers in the area...since then she has not had the issue. Another interesting thing is I have been having issues receiving calls at my home, straight to voicemail. Finally called Verizon since this last time nothing worked, reboot, airplane mode toggle, etc. They did something on their end and all worked shortly after. Not sure its related, both my wife and I have iPhone 12 Pro...Blue and black. Never had issues with the 11 Pro or X.

I've gone through this before, but basically newer models of iPhones can use more LTE frequencies than older ones can.


When your phone connects to the cell tower, it tells the cell tower what frequencies it can use, and the tower says "use this one."


However, if the tower isn't properly configured, the frequency it tells the phone to use may not be one it is optimized for or can use at all.


It's like if you ask someone what languages they speak and they answer "French," and since you took French in high school you say "Oh, I speak French, too" and then the other person starts speaking in rapid conversant French because they lived there for two decades.


You'd be lost, even though you told them you could speak French.
