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.

There was a change to my plan when I ordered my phone and AT&T put a code on my account. It wasn’t clear why or what the code was only that it was an accident. To fix it they changed my plan and resent it which made my phone work. Then they changed it back and now I’m good.

Went through that with Verizon and basically the network team is just gathering information and told me that they are working with Apple on the problem but have no fix right now . Spent hours on the phone with Apple and Verizon. Going through all the things I’ve already been desperate enough to try myself only to get to the end and hear them both blame it on each other and tell me yep you have a problem. Fun fun fun .

The guy at Verizon and apple did confirm the issue though and they both said the blue one has had the most issues with this problem and you guessed it mine is blue apple was supposed to be teaming up with my carrier for a replacement or solution but nothing has happened at this point that was days ago but I will say that Verizon has been more than helpful trying to help me figure this out I’ve done everything that can be done as far as software on my end and the apple store completely wiping the phone and running it bare bones I know this phone as well as apple now and that’s just crazy because it’s a lot I’m completely overwhelmed this is affecting my life as I don’t have a backup phone and this one is completely unreliable causing me more issues than I need times are tough enough as is apple needs to step up and get this fixed whether it be a carrier problem or a apple problem this problem is big I would say in the thousands for sure

Hi


Did you get any solution to your issue? I am from India and have been using the 12 Pro since Oct 2020 and have faced similar issue randomly atleast 3-4 times till date.


Toggling the Airplane button doesn't help me either. I have to shutdown and power on the phone again to regain the network. Although we don't yet have 5G here in India, I am using LTE with a physical sim and also an e-sim and both lose the network. Now these are again two different service providers, so I am pretty much sure there is no network or sim card issue.


Prior to this I was on iPhone X for a good 3+ years and I never faced such issue once.


But as I said earlier the issue is random and have faced this 3-4 times since Oct 2020.


Do let me know if you have found any solution on this.


Thanks.

Nobody seems to care about this problem. 3 plus months now since I purchased my 12 mini and none of the upcoming IOS updates seem to reference this issue or have a solution for this issue.

All anybody can do is remove 5G from your phone and remember to "toggle airplane mode", on & off, so that your phone can regain the service/signal strength.

After the numerous tickets I created with Apple and Verizon, do you think either has responded to follow up, offer a solution or have an update? Nothing at all. Just silence! What a shame!

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.

I’ve recently noticed that when this is happening the signal strength is actually grayed out. Its showing all the bars, but gray, and LTE is still in black letters.


It’s completely random and usually about 30minutes or more. I now keep service on my old iPhone7 and have it with me just in case I need to find a business or whatever when driving. I’m guessing that this could be a hardware issue on a certain number of phones because if it was an iOS issue they would have fixed it already. I’ll wait another month for iOS, otherwise I’ll get a 12pro to see if any difference 5 months later. Very upsetting

Tom-From-Calm,

I use Verizon and all I know about this extender is that Verizon offers this to customers at no charge when signal strength is problematic. I was told this extender is the latest and greatest and offers the best service. It was easy to set up and has been working wonderfully. Now I notice constantly having 4 bars and never worrying about signal strength at 1 bar or no bars.

I'm still upset there was a problem in the first place but hard to deny Verizon stepped up with the free extender as promised.

I even notice when going down to the garage that I have 3 bars. Prior to this extender I would lose service downstairs and lose connectivity. Huge improvement huh?
