iPhone 12 losing service

It hasn’t happened in the last few weeks. So I am convinced it’s the 5G thing that’s the issue. It’s much better now though!!

Explained several posts before yours, here:

Can't be fixed until the cellular providers reconfigure their towers.

That was my point the whole time. I have no app installed (though VPNs aren’t bad lol) and my AT&T iPhone 12 pro has this issue. AT&T said they’re aware of the issue and should have it resolved within a week. I think they were just telling me that to get me off the phone.

Nobody said it was a VPN issue. Some barrack room lawyers just like a place to write essays.

Apple Support did what many volunteers on here do and recommend removal of unnecessary apps that are *known from experience* to cause many problems. VPN and third party security (Avast, Norton....) being the most notorious.

Once the **** has been removed you can try and diagnose any problems that remain..

Getting a new SIM did not solve this problem. I have considerably worse coverage with my 12 Pro than my previous 8. Even when it is on LTE vs 5G getting dropped calls and others can’t hear me. Very frustrating, deciding whether to downgrade to the 11 Pro.

“...Getting a new SIM did not solve this problem....”

12 days ago, when I suggested it, that was the best information on the grapevine.

Now the recommended action is contact Apple tech support, or network carrier help-desk if they provided the phone.

Apple has been struggling with antennas since iPhone X (Apple vs Qualcomm problems) and it’s getting worse every year. Unless there’s a software workaround acting as a life support, I hope they give us the option to turn off 5G without hiccups.

I cannot make or receive phone calls on my 12 Pro Max, whereas my iPhone 11 Pro Max works fine from the same location. I'm returning the 12 because the upgrade program requires returning the 11 soon, which would leave me with no working cell phone. Clearly there is no solid solution yet so it's better to bail out before the 14-day return "privilege" lapses. I wonder how widespread this cellular service problem is?

I am on Verizon and on my 2nd iPhone 12 and 3rd sim card. Since I have had the iPhone 12, its dropped over 2,500+ calls and over 300+ Facetimes. The worst is when I am on Zoom calls all day long and I have to call back in latest 16+ times a day. I have tried WIFI calling it's worse. I have tried cellar with having 1bar or no bars at all. This morning I shut off my iPhone 12 and went back to my reliable phone iPhone X. When they fix iPhone 12 and Verizon fixes there 5G. I will re-hook up my iPhone 12 yet I paid for something I cant use.

Same thing here. Drop to no service constantly with my iphone 12. Never had a issue with my iPhone 8. Places where service was bad I still received calls and texts, now I have no service for hours. Did all the resets and factory restore. Made sure all the updates were up to date and even swapped SIM cards once. Still same garbage. Apple never contacted me back when I was texting with them and lost service. Verizon has no answer. The phone is a paper weight. This will be the last Apple product I buy. It’s insane that this has not been fixed.

When I got my new iPhone from Apple I couldn’t get it to connect with my provider. I took it in to Verizon and they had to put in a new SIM card. They got it working but were a little confused with the Primary/Secondary. I have had a a few calls that would not go through and when I text it appears some contacts are Primary and some Secondary which causes some conflicts. Today I updated my phone and now I have no service. Tried phone support but they say they can’t reach me. Their call comes through but won’t allow me to do anything. Have toggled Airplane mode and restarted. No Luck

ever since I got the 12 pro max I been having no service issues as well. Spoke to Verizon and they said there’s no problem with the service in my area. They told me to master reset my phone , which I have and still the same issue. They stated that if I continue having these issues that they would seen me another phone cause I’m still under the 30 days , but honestly if I do get another phone I feel like the issue won’t get resolved

I have the same problem on Vodafone in Australia. After coming from an iPhone 11pro to iPhone 12 pro. My new phone just loses service completely sometimes and in some instances just shows 3G. I haven’t seen 3G for many years but now I find myself dropping to 3G more often than not - or no service completely. Only regular solution that works to restore service is to reboot phone.
