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).

The good news is that I can save you from an excruciatingly painful series of resets and re-starts, network fixes at the carrier, re-provisioning and other settings. None of them will work. I haven’t seen a single thread that shows a solution, so save your time and energy and wait for a fix. Wall Street analysts follow these forums and they are on the case. It is far more efficient for Apple to craft a fix than lose one dollar per share. Apple has about 17 billion shares outstanding. It has to be cheaper to fix this.

Keep up the reports here and on Apple Support. Eventually they should respond. I just don’t think they know the solution yet.


Note that Apple Support will never respond here.


While some have been contacted based on posts here, it is because of individual employee initiative, not because of corporate process.


To lodge official reports, to which Apple Support may respond, please do so by contacting Apple Support directly.

iPhone 12 Pro Max, repeatedly completely looses mobile connection, leaving me with no internet.


I have a lock free phone and this problem is present while using both physical and virtual sims on different carriers in US, Europe and Asia.


Switching airplane mode on/off helps sometimes.


Remarkably, even when the phone drops all service the signal bars are full and LTE/5G indicator is showing.


This is extremely annoying and disruptive for everything - work calls, ubering around, ordering food. EVERYTHING.

My iPhone 12 Pro stopped responding completely as of Thursday morning 12/3. Woke up with zero apps working, no network connectivity, no WiFi, can't restore the phone because I can't turn off Find My which requires network connectivity. Apple support chat has no idea what's going on and the next available appointment around me is in a week.

I have the same problem. I spend two days fighting with Apple and Tmobile. They are pointing fingers at each other. I received my iPhone 12 pro max Dec 2, 2020. And my frustration with Apple and Tmobile being unable to replace my phone with a brand new one makes me the angriest man on planet earth. I’m a nurse and I use this phone a lot to communicate with doctors, nurses, hospitals, and with my patient. And they are making my life and the people I serve during this pandemic in jeopardy.

Here's an update for anybody that has Verizon. I have the 12 mini and over the weekend I phoned Verizon to report the problem, after 2 hours with a level two tech, the decision was to send me a brand new 12 mini phone. Received the phone today, phoned Verizon tech support and we activated the new phone via a call.

Now I have to return the "broken phone" within 5 days.

Anyway, I can't say for certain what Verizon is doing that other carriers are not and I can't say for certain this new phone is going to avoid all the issues I had previously. Only been a Verizon customer for 3 weeks and this is not a good beginning but I have to applaud their service for sending me a new 12 mini phone within two days.

I urge you all to call your carrier, demand a new phone or the right to return the phone and get a refund. No reason to toggle with airplane mode, turn the phone off/on to restore service. Phones are NOT supposed to work that way.

Good luck!

Five people in our shop bought IPhone 12’s 2 of these phones work fine one on AT&T and one on Verizon. 3 of them work for crap one on T-Mobile and two on Verizon we can’t get any of the three to stay lock on a signal as a matter of fact most of the time we have no signal. We have changed sims reset the phones toggled airplane mode off and on and it is ridiculous what is going on. We all have had IPhones before this without any issues I really believe this is a hardware problem because two of these phones work fine. Please Apple get this figured out!

That is a false recommendation. You should be able to use ANY reputable VPN on ANY iphone. Why would you want to? Becuase EVERYTHING sent from your phone over public networks can be seen by people like ME that have ability to read traffic. You dont need for private networks obviously, but anything public should use VPN if you can. Doing anything like banking over public net is plain dumb. Apples technology and infrastructure has NOTHING to do with data sent over public networks.

Four carriers to fix a problem that affects only a single model of hardware vs one hardware manufacturer to fix a problem that affects all 4 major carriers (in the US at least, not counting outside US).


I’m betting on the one hardware manufacturer.


In actuality it’ll likely be a joint effort.


Truth is: I don’t care. WHO fixes it isn’t of concern to me as long as it gets fixed relatively soon.
