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).

Phone : Iphone 12 mini.

Carrier : Telenor, Sweden. (No 5G at current location)


Previously used phones with no issues :

Iphone: 7/8/X/XS/XR/11.

Ipad: Mini/Air/iPad 2019/Pro. (Cellular)

Samsung: S7/S9/S10.

(except known issues with X)

Phones active in household (family of 4) without issues: iPhone 11x2. Iphone 7.

IPad Pro with cellular. Ipad air, cellular.


Tried : All mentioned in the thread. As most have. Change of Sim/E-sim. Restart, put into airplane mode and so on.

(For the price of this phone. It SHOULD not be needed. Considering other options)


Started directly after setup. Have had issues previous with restoring from backup so I install as "new phone".


Problem :

Starts with No signal > searches forever > skips the signal from 4G entirely and choose a 3G connection.

(And this is several times per day)


After a while it might find a 4G connection but it's always extremely low in downloaded data. Never had this issue and almost always had (110/30Mbit/s)

And low ping ~30


Now usually the upload speed persist but D/L falls down to around 2-3Mbit/s.


My operator blames apple, Apple use the

"No no, not us, it just works"


So where does it actually work is my question...

I have no intention, or license, to give you, or anyone, legal advice. But if someone sells you a car that doesn’t work, ever, and you try to make it work for 14 days, and in good faith, you cannot make it work, I don’t think any court in the USA (you might be in another country) is going to enforce the sale and the 14 day return period. You were never delivered a working product and the seller never held us their end of the bargain.

This makes certain assumptions.


For example, if the device would work on another carrier, that means the product works, but the carrier's network is to blame.

My 12 pro max has been doing the same thing. I am on sprint/T-Mobile. Resetting the phone/network settings has yielded the same issues. The phone calls coming in will sometimes go straight to voicemail when the phone isn’t even being used. Calls will just drop on lTE/5g and WiFi. A lot of times the other end of my calls will complain about the quality of the call.

this is beyond frustration for the cost of the phone.

I never had this issue with my 11 pro max. I wish I would have kept it another week as I would have sent the 12 back!1

‘...Yes, the issues are genuine for the many (thousands?, tens of thousands?)...”


Evidence?


I accept most of the people who come here to describe their connection issues are genuine.

The “me-too’s” are more difficult to police.

To jt7577 This is not grammar policing it is truth and evidence policing.

Describe your problem, but don’t make up the statistics without a link. Forbes don’t count as evidence because they just cite this thread’s me-too count. plus Reddit threads that I cannot find. Most of those (iphone 12 megathread for example) were praising the phones.
