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!

I am once again not getting phone calls from one person in my contacts who does not have an iPhone.

All I can say from my several months of experience on this subject, call your wireless carrier and demand they take action.

Maybe they can send you a new phone. Maybe they can send you a network extender. Maybe they can provide a discount of some kind. Be sure to take action or else nothing will be done.

The latest iOS update has not corrected this issue with the phones.

I have gotten a replacement iPhone 12 mini, and a new sim card. no difference. Apple says its Verizon, Verizon says its Apple.


WE PAY TOO MUCH for Apple and Verizon to be having these issues.


I can say its an Apple issue because my coworker has an old Samsung and she gets fast service. Her Snapchat downloads super fast. we have same Verizon plan.


Apple needs to hurry up and fix this issue.

I also believe it’s an issue with the iphone itself. Also, are you having problems with your 5G Data? Mine for example takes lots of time and sometimes it’s impossible to stream hi-fi music through tidal even though it marks as having 5G and I believe that even with 4G LTE it shouldn’t have a problem with playing a mere song. On wifi I never have these issues. I’m guessing it must be a problem with the way the iphones get signal or data from carriers. I hope they investigate this soon and issue a fix since it’s happening to a lot of us and it’s really frustrating

I got a new sim for my phone and they switched it out of 5G autos/on to LTE and it made no difference. Still if I lose service I have to reconnect it myself it doesn’t come back on its own. And they told me I could try a different iPhone 12 but it will most likely have the same problem. I know numerous people with att and they are not having this issue

I just got my new iphone 12 pro. And once everyday it would reception. And im using dual simcard. So it can’t be the network since there’s no way i can lose both at the same time. It’s very frustrating and sometimes it disappeared for 2-3 hrs. I live in Indonesia so i guess it happens all over the world. Shall i return this and back to my old iPhone?

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.

On the other hand, if your Lamborghini broke down every time you got gas at one particular gas station chain, would you continue to get gas there or blame Lamborghini?


It appears the issue is the cell towers are telling iPhone 12s to communicate with the tower using a frequency the iPhone 12s support but the towers aren’t properly configured for.


This causes iPhone 12s to report no or low signal when other cellular devices (that have not been assigned to the channel in question) do not.


The solution is to either reprogram the cell tower base station controllers to not assign phones to use that frequency, or to properly configure the tower to be able to use those frequencies.
