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 have been having this same issue in London since he first week of the iPhone 12 pro release... and its highly frustrating. I called Apple and they kept me on the phone for over 2hours, to NO avail.

Its like the customer service has gone absolutely downhill since.

I’m carrying 2 iPhones at the moment just because my new phone is SOOOO unreliable.

I don’t know if this is helpful or not but it’s for sure interesting. I’ve been having the same exact issues as everyone else and ive tried everything!!! SO I decided to turn on wifi calling. Since then my cellular service bars haven’t dropped nor received the “no service”. I haven’t had the chance to leave my house and try it while it’s on and see if It still works.


I know what some will say..you’re on wifi so that’s why you have service BUT the phone would say no service regardless if I had wifi or not. Try it out and let me know if you are experiencing the same thing as me. At least now I can get phone calls at home and carrier text messages!!!

I bought the new iPhone 12 about 2 weeks ago... I have consistently had dropped calls. I call Verizon my carrier and while talking to them on several occasions my phone dropped called several times, they said to reset my network which I have done both at home and work, - twice no less.

Still frustrated and having issues, I went to the Verizon store last week only to have them swap out the sims card. Still having issues with it. Went back today 11/16/20 and they want to send me a replacement phone.... WTF, I didn’t “like many of you” shell out over a $$ grand for such garbage and a refurbished phone. I’m ready to move to an Android

I had trouble with 4G & 5G on my Verizon iPhone 12 Pro from Verizon where it would drop to no signal while using 14.2.


After reading similar problems on Reddit, I set my cellular options to No Roaming and LTE. This worked pretty well for four days with only a few No Signal problems, that could be cleared up with Airplane Mode toggle.


Last night I decided to turn off WiFi and set the cellular settings to No Roaming and 5G Auto. It’s been working for 24hrs with no No Signal problems. I see 5G and 5Guw at home.

The iPhone 12 is defected , I’ve tried every troubleshoot possible and still have no data connection .. I even have full bars on lte , and still can’t upload my google page due to “ no connection “ . I’ve ran tests with a Verizon technician .. and they still can’t figure it out . I have lost numerous phone calls within the last few days . Really important phone calls .. I’ve read a lot of people having the same issue . I will never be purchasing a new apple product again as this has caused a serious issue as far as headaches etc .

The same with the iPhone 12 pro, its a defective product that’s just frustrating on all levels. I’m NEVER going to be quick to buy an apple product again myself. The Customer service do not even want to acknowledge the fault either, when i called again.


Fortunately i have a spare phone handy, and i have to confirm, its not my networks issue in London, UK.

The fact that I have one of the latest products and it’s SO unreliable is a JOKE

I’m from Bangladesh and this is happening to my IPhone 12 pro as well. I’m loosing the network frequently and to get it back, I have to restart my phone.. putting it onto flight mode doesn’t work and I have to shut down and restart my phone to have my network back. This is insane!

this IPhone 12/pro seems to be the worst one ever made.

I’m already facing serious battery drainage and also at the same time, phone is getting hot while usage and now, this network issues... such an expensive phone and with all the issues, Apple should have been more careful before launching this..

never had this issue with my 11 pro. I totally regret ...

Not satisfied at all with the new phone 12Pro...


if any has any solution to this, kindly refer.

thanks

I'm now on my 2nd iPhone 12 Pro and still having the same issues. Mine drops calls only in a certain areas around where I live but I still have 4 bars of signal reception! Basically the person I'm talking with can't hear me but I can still hear them or it just gives me the call failed screen. All with 4 bars! I've called Spectrum multiple times as well as Apple and they both blame the other one for the problem. I've tried every option, diagnostic test, SIM card swap, replace the phone, reset carrier settings, etc. and nothing has changed! My new phone that I just set up yesterday literally said Call Failed on the very first phone call I made! I'm pretty ****** since I've spent about 10 hours on the phone and going by the Spectrum store only to get the same results; which is nothing! I had an iPhone 8 that worked flawlessly on the same network but unfortunately traded it in on the new 12 Pro. Everyone else I know in the same area with Spectrum doesn't have these problems but none of them have a 5G phone. It seems to be related to that for some reason. I'm about to send this one back for the 11 Pro and hope that resolves it! No idea what else to do!
