iPhone 12 losing service

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.

Does anyone know about Spectrum carrier updates? I’m guessing if Verizon does one it affects Spectrum too? I’m still having issues with the 12 pro dropping calls with 4 bars of service in an area where there’s 5G towers. Even with it just set to LTE only.

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.

I’ve had the no service issue since getting my 12 pro max. It’s ridiculous. I’ve missed countless calls. My phone will lose service and no regain it again until I either shut it off or turn airplane mode on an off. I’ve called Apple and they blame Verizon. Verizon blames Apple. I’ve had 2 new SIM cards now and no change at all.

For $1300 this is ridiculous. I’m glad I have a Note 20 ultra. Guess I’ll have to use that until Apple fixes this.

Why didn't you return your 12 Pro Max for a refund?

Note that in many areas Apple has extended their return policies for the holidays.

For example, in the US:

Items purchased at the Apple Online Store that are received between 10 November and 25 December 2020 may be returned up to 8 January 2021.

I'll never understand why anyone keeps any product with the hope it is fixed "someday;" it makes more sense to wait to see if it is fixed, then purchase it.

That having been said, I have never had mine do this, but I also don't have 5G on my plan.

If they’ve given up their old phone on a trade they wouldn’t have a device to fall back on if they were to return the new phone. I can’t get a new device because my carrier is back ordered on my specific device and the Apple store has limited Genius Bar appointments as a result of COVID.

I am having the exact same issue. I am in Germany and have tried enabling "5G On" but it still intermittently drops the connection to the cell tower when being on the go. It's frustrating. I am going to contact Apple ASAP

I have the exact same issue with the iPhone 12 pro Max dropping service at certain places. The easiest way to fix it is to toggle airplane mode on and off. Obviously not an acceptable fix for an $1100 phone. Also requires that you check your phone to make sure it hasn’t dropped service if you are expecting a call or text.

I took my phone in the Apple store (11/24/20), they ran a diagnostic (found nothing wrong), reset my network settings, and gave me a new Verizon (my carrier SIM card). The person I spoke to there said others have reported the issue, so Apple is definitely aware of it and for me to contact Verizon about the issue.

I talked to a Verizon tech today (11/27/2020) that said they are aware of the issue for over a month and are sending reports to Apple about it. They recommended not switching to the SIM card provided by Apple as that won’t help. They do not have a fix for it other than to toggle airplane mode on and off, or turn your phone off and on. They are sending my info to Apple to along with others.

The best option right now is for anyone with this issue to report it to Apple and your cell carrier (Verizon or other). That way they hopefully find a fix if enough people formally report it, and someone company admits there is a problem with the iPhone 12s. Currently no one will officially admit this is a real problem with the iPhone 12s.

Same as many people: I have a 12 Pro Max on Verizon and live in an area of fringe LTE coverage and no 5G anywhere nearby.

My phone was often sitting in “No Service” about 30% of the time I pull my phone out every day. Toggling airplane mode on and off fixes it about 75% of the time. Sometimes I had to reboot, occasionally I had to reset network settings. Data roaming is off. I tried turning 5G off, with no impact and it still drops to “No Service”

AT&T has better coverage in my area these days and my wife was not seeing any issues on her 12 Pro on AT&T, so I activated an account with AT&T and added it as an eSIM to my 12 Pro Max. For those that don’t know, 5G is currently not supported with dual sims and this forces both lines to 4G.

Since activating the eSIM line 48 hours ago, I have not had Verizon drop to “No Service” even once.

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

Replacing the sim does nothing. I’ve done everything you can possibly imagine trying to resolve this issue with my 12. Replaced SIM card and no better results than the one that came in it. I’ve done a master reset, network reset. I’ve spent hours on the phone with Verizon. I believe the antenna is weak. For me it’s just my upload speeds. The phone is receiving data fine but cannot seem to push it back to the tower. Can do a side by side speed test with my wife’s 8+ her upload is normal mine is almost nothing. May be fixable with an update but I’m fairly confident the antenna is garbage.

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 am having significant network issues with the new iPhone 12 . Calls are dropping suddenly and signal is not very stable .

Comparing with my iPhone XR , I can definitely see that I am getting poor signal comparing IPhone XR .

very unexpected and planning to return the phone unless there is an solution .
