iPhone 12 losing service

“..:You think people are seriously randomly coming here, logging in from their personal iCloud address, and making stories up? Huh...”

If you saw the amount of Spam I report every day then yes I can believe that rival companies (as well as advertisers and poseurs) can create an appleID in order to add to the me-too’s

You have to think from a business perspective. Is it in a carrier or companies best interest to announce at holiday season yeah guys, our most anticipated phone in 5 years has major issues? Obviously not. No company or employee is ever going to do that. We paid hard earned money for these phones, and regardless of 14 or 30 day periods, they need to stand by them and take pride in the quality. If it doesn’t work, that’s not the consumers fault. We have a one year warranty. Help us.

So I’m home on the phone and bam my phone says no service, So I think to myself let’s restart the phone which I did ..... didn’t work. So then I say let update my phone and try again .... that also didn’t work. So now I’m here and have no clue what to do

I am in Italy and have had the same problem with iphone 12 pro. I tried everything but nothing the phone was losing the telephone network. I returned the phone and went back to Iphone xr which always worked perfectly.

Just bought a new Iphone 12 PRO Plus. Keep having very little to no signal significantly impacting my usefulness. Is this a Software or Hardware issue? Old iPhione Xs had NO problems! This is not a good way to start.

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.

Note that "weaker" is not always easy to determine.

Signal bars are relative and only for that device; three bars on an iPhone 11 does not mean the same absolute signal strength as three bars on an iPhone 12.

Started having this issue several times a day after I upgraded to a new iPhone 12 Pro Max at Verizon in Orlando few weeks ago. Preiodically keeps disconnecting me, sometimes I see a popup message CALL FAILED during a phone call. I upgraded every year to the newest mode in previous years and never had issues with connectivity. This is so annoying. What is Apple going to do about this?

Balanced analysis. Stick around!

Btw I regard having no spare iphone because it was traded in, as poor planning as having no software backup .

Some day the phone needs fixing like a warranty fix or a new battery and may be away for 2 weeks in a pandemic. No good only having only one phone for the sake of a few bucks trade-in

IPhone 12 Pro just updated to iOS 14.3 and I’m dropping calls, 5 drops within 45 minutes this morning while driving. Have not experienced dropped calls with this phone prior to this update. Carrier is t-mobile and WiFi calling is on.

FWIW, I recently drove approximately 4,000 miles round trip across the US on interstate highways using Waze on this phone and was connected to 5G for most of the trip. Excellent voice and data coverage. My connectivity issue began this morning after upgrading to iOS 14.3. Location is NE suburban area of Atlanta, GA.

Any suggestions for a diagnostic path to isolate issue? Turn off wifi calling to see if there is a handoff problem? Restrict to LTE only? Your help is appreciated

Update to my December 15, 2020 post above.

Today I’ve experienced no issues. Perhaps it took some time for the update to settle it?

Regardless, I’m back to no connectivity issues and very happy with my iPhone 12 Pro

I have the same problem in Ukraine this iphone 12 pro. Lifecell operator.

Calls do not disappear, but the Internet on the LTE disappears periodically.

Updating to 14.3 did not solve the problem.

The phone was bought in the USA.

How to solve the problem without giving the iPhone to the service in Ukraine is not clear here :(

My 2nd 12 mini is still having issues. Verizon thought they fixed the problem but the 2nd new phone has done nothing.

I have a 11 as a work phone and with a different carrier that my employer pays for. I notice day after day this phone has no issues and the signal strength is consistently high. Much higher than the 12 mini with another carrier.

This issues have to be with the 12 models and the carriers, no?

That's good as many of these issues have unique causes on each person's device.

These are not due to a global issue with iPhone 12 family phones or there wouldn't be millions using them without any issues whatsoever.

They key is to try to figure out what's different about your configuration or network that is causing an issue.

Good luck. Verizon told me something very different. They instructed me to have 5G auto on and they also suggested that I enable WIFI calling. Something I have never done prior to getting my 12 mini and something I never needed to access when I was an AT&T customer.

Something tells me that Verizon has no idea what to do, their tech support staff also has no clue and the customer has to take it on the chin and either stay with the horrible phone or beg them to exchange for something else.

I'm on my 2nd iPhone 12 mini since last month and they both are equally performed terribly and exhibited the same problems.
