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 just got an iphone 12 pro 2 weeks ago and it's been dropping calls several times a day. Using both wifi and 5G. And standing in one place, not even driving, as many people have stated. I'm also not getting all my text messages. I'm with Verizon. Apple says it's Verizon's fault and Verizon says it's Apple's fault. I feel like I should be offered a refund by Apple.

My Wife and I just Activated our brand new iPhone 12 Pro phones with Verizon. The Voice or Audio drops completely out and you can't hear the other person until the Voice returns. It keeps fading in and out while driving. I don't appreciate paying $1,100 a piece on brand new iPhone's for to be having complete loss of Voice or Signal problems. Verizon puts these 5G Tech Commercials out on TV like they have been doing all of this testing of their new 5G network. Apparently there is a major Apple iPhone 12\12 Pro issue going on with the new iPhones or it is a problem with Verizon's Network.


The major question is, Who is going to step in and take responsibility to fix these new iPhone 12 issues?

My iPhone 12 Pro Max drops service and I get “IPhone is not activated, please contact carrier” anywhere from 10-30 times a day. Toggle the airplane mode and service reactivates. Apple gave me new phone, Verizon gave me new SIM, still not working. Have tried digital SIM. Happens mostly at home so not switching towers. Have spent about 12 hours over last few weeks with Apple/Verizon reps restoring, trying different settings to no avail. Sent screenshots to Apple, still no fix. Very frustrated.

Just to be clear. When manufacturers build products. The have multiple manufacturing supply chains that provide all of the different parts.


That’s why when a certain product has a fault they can usually track everything with serial numbers back to the production line of a time period and plant number.


If one of those supply chains had a bad run of a certain part and was dispersed and installed at several factories, this would make only X amount of devices have a problem.


Again this is only speculation from how manufacturing issues can take place in general but a likely scenario


whoever you are, you have no right to tell people here what the problem actually is and if your not having an issue yourself, you should not even be on this forum.


The behavior you are exhibiting here on this thread is what is known as “Trolling”


I suggest you just let everyone tell their story and let Apple take all of this feedback and figure out what the problem is.

If it’s hardware or software or if it is found definitively to be a carrier issue, Apple will then come out with their official findings and provide a resolution.


Happy Holidays to Everyone!

You will not be able to point to a single post where I've told people with issues that they were wrong, simply because I've never, ever said that.


All I've done is offer possible explanations, and the most likely explanation to date is that this is a carrier configuration or equipment issue, not an Apple issue.


I've explained why I believe that; you are free to believe that or not, it really doesn't matter to me.


However, if I see a statement stating that these phones are clearly defective and they all need to be recalled because they don't work, I will point out that's definitely inaccurate.

The bad news is that whether it’s a software issue, hardware issue, firmware issue, 5G issue or carrier issue - it’s affecting many people in many countries on many carriers and still hasn’t been fixed. It’s not my job to keep troubleshooting the issue for them. Apple and the iPhone 12 devices themselves are literally the only constants in this thread. Many carriers, many towers, many bands, many locations, many people, but only one type of phone made by one company. I’m counting on the company representing the one common element to provide the fix, regardless of whose fault it is.


What have your carrier and Apple Support said when you've relayed these details to them?

Are you giving the feedback to Apple Support?


Once again, if you're just posting here, no one who can address the issue at Apple will ever see it.


Apple Engineering does not read these forms except perhaps if a member reads them on their own time, but they don't on company time.

Likewise, Apple Support does not read these discussions except to monitor for violations of the Terms of Use.


If you do not contact Apple Support directly they will never know what you have to say, no matter how many times you or others post here.

My wife and I both got iPhone 12 pros in October. ATT service at our house is poor, but we had been very successfully taking advantage of WiFi calling on our previous iPhone 8s. On the new 12 Pros however, virtually every call gets dropped with or without wifi calling on. If however we put the phone in Airplane mode, then wifi calling works perfectly. Of course everytime we leave the house, we have to remember to take the phone out of airplane mode so this is not sustainable or acceptable.


Apple needs to fix this problem that seemingly people all over the world are having!!!!!!!!

My iphone 12 pro has the same problem but with 4G. We do not have 5G in our country, however, the upper bars keep fluctuating from 1 to 4 bars most of the time it is 2-3 bars. I called Apple Support and they don't have an answer.


‏I don't completely lose the signal but some people told me when we tried to contact you over the phone, we got a message saying that you are out of coverage.


I think Apple has major issue with the iphone 12 signal with 4G and 5G.


I have 4 more phones (android, apple) and all of them are free of problems and give full 4 bars.

It’s already been replaced. The replacement had the same issue.


It’s not device specific.

It’s not physical SIM card specific.

It’s not eSIM specific.

It’s not location or country specific.

It’s not carrier specific or person specific or weather specific.

It’s not 5G or LTE specific.


The only specifics and constants are: the brand and family of the iPhone (i.e. Apple + model of iPhone 12.

No surprise there, it is not trying to use 5G.


Be aware there are many reports that (in particular) Verizon’s 5G in most areas is a lash-up of spare bandwidth on their 4G network. There is no surprise it has limited coverage and doesn’t work properly. Here is just one such report, and there are plenty more if you look around.
