iPhone 12 losing service

This is happening to me when at home and connected to wifi. If I'm on wifi it just drops the cell connection and if someone calls me it will ring on my watch and not my cell phone. I look at my phone and wifi is on and wifi calling is on but calls don't come in and if I try to call out it fails as well. I turn off wifi and after a few seconds cell service will reconnect and calls with come in and I can call out.

Sadly I've switch to T-Mobile before and in my area their coverege is just bad. AT&T is the best coverage but slow and Verizon is good as well but way faster than AT&T. It's only and iPhone 12 issue for me. My wife has an 11 Pro Max and doesn't have this issue. I'm using TiggerFlute777's idea of 4G only and so far it's worked for the last 24 hours.

I have iPhone12 Pro Max with physical SIM for ATT and an eSIM for Tmobile. Does not matter which carrier I use I am getting long delays before connecting if it connects at all. I have been getting several failed call attempts in a row.

When I do connect I am getting scrambled sounds as if people are trying to talk but when I finally get through people will tell me they could not hear me speaking at all.

This is an unlocked phone purchased direct from Apple.

My 11 does not have this problem. Do not buy this phone unless they push updates, if you are having the same problems make sure you post and describe it so this inspires the company to either fix or replace the them.

I got with technical support and they got on looked around and said if it happened again they would have to reboot the phone or replace. Since that time I have not lost service again. Not sure if it’s fixed or just has not happened again yet.

Setting ip new phones or computers as new then only transferring back important data like photos, music and docs has always been my preferred setup.

I keep media on my mac and sync back, and keep all documents in a cloud. So I can easily set up phone as new any time I like.

The whole reason for “backup and restore” is for people who keep everything live on the phone and in particular social media history.

If you manage media and data externally and have a healthy disregard for ‘what who said what about who’ in Whatsapp then the clean sheet setup typically has many less bugs.

Seminar over.

3 phones, 2 max pro and 1 pro as stated a month ago, ATT and one of the pro max has a T-Moble eSim same problem as everyone else.

Some people on here are stating if you do a clean install and do not transfer the data from an old phone that they do not have problems, since you have hundreds was that the case? Did you do clean installs or use some corporate software to update them?

I have the iPhone 12 Pro with a 5G/4G enabled carrier in Spain. I'm also experiencing the same issues, doesn't matter which location I'm at or if I'm moving around. It's almost constantly dropping(3-10min intervals) the connection while switching between 4/5G. Practically the phone is unusable on anything else than my WiFi connection.

I too have worked for a decade in telecom and have never come across an issue this dramatic to where the phone DEACTIVATES, not just drops calls. The close I’ve seen were with CDMA CSpire iPhones when they first launched with the iPhone 4S, but that was quickly corrected and was only an initial activation issue, not a reoccurring issue. This is AFFECTING EVERY MAJOR CARRIER AND IS UNACCEPTABLE.

So what you’re saying is the phone deactivates itself anytime it loses reception? That’s easy enough to test with a Faraday bag.

Point is, were that the case everyone with an iPhone 12 that lived in a mountainous area would be experiencing the issue, and we don’t see every person whose ever driven through the Colorado mountains or rural areas of the US complaining of the issue.

Still, I’m willing to buy it if it can be reproduced with a signal blocking bag, but I don’t believe it’s that simple.

Almost 2 months ago Verizon sent me a 2nd phone and 2nd SIM card and still no luck. Does not matter how many phones they send you or SIM cards, that will not fix the issue. I am on my 2nd phone and still having issues. Nobody from Verizon cares and seems like Apple does not either. In an earlier post I discussed how Apple made a slight effort to call me and fix the issue. I did a diagnostic check and sent that info to Apple. Crickets since! No more phone calls and replies to my emails. RIDICULOUS!

Do yourself a favor and just get rid of it. There is no fix. Not sure if it’s Apple, carrier or both but it will continue to not work. What I do know is my 12 will not have service at my place of work at all. Also I often drop calls and service at home. But yet a 5g capable phone from Samsung works just fine at my place of work in the exact same place. At this point I don’t care who’s fault it is. I need my phone for work and it says no service for 8 hours a day.

Like others have said I have to assume it is a issue with the bands and tower locations. Could it be faulty hardware on certain phones during production? I don’t see why not. That happens in every other manufacturing platform so what makes Apple invincible to that? Others are so sure it’s a carrier issue and that’s fine, but there is no way to say that’s the case until the carriers fix the issue. If it’s never resolved then I would have to imagine it’s a manufacturing hiccup.

It is not just Verizon, there are a number of people that are overseas having this same problem, most of those use GSM which is the world standard, I mentioned before I have AT&T and Tmobile, both GSM networks.

So please stop, I love your passion but you are not helping to solve this.

Verizon is the largest carrier in the US, of course they are going to have more problems then everyone else, 2nd, of the three phones I mentioned I am the only tech savvy person, the other people grit their teeth and deal with it, that does not mean they are not having problems, the majority of people just call tech support or phone company and like the others here jump through hoops to try and fix it and just give up because they are tired of it.

The best option and I have talked to Apple Business is to return the phones and go backward, lucky for me I have two of old iPhone 11 Pro Max and can switch back at no cost.

Again, unless you can provide scientific answers that prove it is only Verizon quit trying to discourage others, you are doing no one any favors. This is how problems drag out.

Apple is not perfect, I have been part of the iMac recall and two different MacBook Pro recalls and we all remember the iPhone antenna issue that they fixed by giving everyone a free case.

I love apples products as much as you but I do not see how you are contributing to solving this, at least others are posting what they have tried to fix it.

This weekend I will try Funky Tangs solution to reset the phone to factory and set it back up clean, will post if it works later.

i used the same sim from my iPhone 11 Pro Max when I changed to the Mini and am getting/experiencing the same service issues everyone else is in this thread. AT&T postpaid plan with unlimited for the 5G access. i get service (never drops) but i apparently get bypassed calls (my phone goes straight to voicemail apparently) and WiFi calling does the same. I reset network settings, turned off WiFi calling and also did a network refresh via the AT&T app but the issues still persist

I just returned my iphone 12 I got Nov 14, 2020 for a full refund.... its been sitting in my drawer collecting dust because I can use it. I went back to my Iphone X with no issues at all what's so ever.... One day when they admit its there issue I will get a new Iphone... I am glad I don't have to pay for a paper weight anymore...... Then if I want i can by the iphone 11 THAT WORKS
