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 understand your frustration. I am a on call emergency heart surgery nurse and depend on my phone for hospital to get ahold of me. I have done all the recommendations tried everything they suggested and still continue to loose service. I finally got a hold of someone at apple who set up a replacement phone I am waiting to receive it and there are no problems with it. Fingers crossed

Ran into this issue today. T-Mobile in Brooklyn, NY. The phone lost service. Calls and messaging failed. Browsing did not work. Restart fixed it but this is super sketchy — especially if you are far away from a charger.


To the bozo that keeps mentioning the ‘wall st. analysts’: let me guess you just discovered Robinhood and bought AIrBNB at $170?

I can tell you from my own personal experience as I’ve been dealing with this first hand. Again, I work in wireless and I have a lot of customers who come back with the same issue. Even when I am setting up the devices for my customers it takes much longer for the iPhone 12s to pick up service than it would for any other iPhone or any other device in general.

I’ll tell you right now my issues are genuine. I would agree that it is probably not effecting all users. However that doesn’t negate the fact that quite a number of us are experiencing major difficulties. I’m being affected directly from my house and almost every call I make is dropped or the person on the line cannot hear me. I have Verizon. Reading many of the individuals that have had issues it seems to be in areas where you’re either switching between towers or there is not an a strong signal. I live in the Las Vegas area where I can literally see the strip from my house. I’ve never had an extremely strong signal but my iPhone 6s Plus could always make phone calls from my house with basically no issues. Accessing data from my house was not as strong.

I have spent hours upon hours trying to remedy the situation and it’s been extremely frustrating.

To JT7577: Yes, the issues are genuine for the many (thousands?, tens of thousands?) iPhone owners who can't connect at all or are having weak signal problems including dropped calls. I've had the same problem with six new iPhone 12 phones, and they were replicated by the Apple field engineer who came to my house to troubleshoot the problem. We've all spent countless hours talking with Apple and our carriers (in my case Verizon) trying to make our phones work properly. It has been extremely frustrating!

I talked with two Verizon staff who confirmed that they are receiving a great many connection issue reports and it was their estimate that this was a problem for "perhaps thousands" of iPhone 12 owners.


"Perhaps thousands" out of millions of phones sold shows that it is likely a carrier issue and I suspect probably has to do with one particular vendor of cell tower switchgear.


That doesn't help those experiencing the issue, but it does show it's not a universal hardware issue.

Hi. I'm from Italy and I’ve been a loyal Apple customer since from iPhone 4. 

I tell you my story. 

One month ago I was very happy to have bought from Amazon my new iPhone 12 mini, coming from an iPhone 8. Immediately, the phone started to loose connection, even if I'm stacked home and I'm smart working all the day. The problem is very bad because nothing advise of the disconnection and people trying to contact me cannot reach me. The SIM is the same I was using with iPhone 8 without any problems. 

I asked Amazon for a replacement and few days after I had a new iPhone 12 mini. Unfortunately, few hours after the phone loosed again the connection. Very disappointed, I've asked Amazon to return the phone and to have the money back. Now I'm back to may iPhone 8, that never loosed the connection for years (with the same SIM). 

I hope Apple will aknowledge that there is a generalized problem and that it will be solved.

At that point only, I could go back to buy form Apple.

I updated but it didn’t fix this problem. Still happens. But it’s weird. Some days I have no problems. Other days it is non-stop. That means it’s got to be a service issue right? If it were a hardware issue it would happen all the time I would assume.


Exactly.


This is a carrier issue that they need to sort out and seems to affect people differently depending upon the signal characteristics of your particular cell tower(s).

I'm assuming I'm not the only one on this thread, but last night I got a call from Apple that wanted a lot of information about my problems (which are much less of an issue than others). They wanted tons of information...what chargers I was using, what precisely happened when calls got dropped.....I never could get specifics as to what they thought was going on, but the implication was that the problem was with the carriers. Just posting this, because they clearly are aware of this problem and are following this thread.
