iPhone 12 losing service

Update on my experiment to make my phone work:

I switched to 4 G LTE on my iPhone Pro 12 (cellular network Verizon). It ran better today, a little slower and glitchy but totally decent. It reminded me of how a typical smart phone runs with modest interference. I had my navigation, listened cable TV broadcast app and switched between phone calls (hands free) while driving 45 minutes away from home and back.

Basically, I will keep my iPhone 12 Pro and switch to 4 G (which is a little disappointing) until the Verizon network (and other effected companies) and Apple get things straightened out for true 5 G availability and phone compatibility on ALL networks.

Some phone companies are doing better than what I have—Verizon, but I have to pay this iPhone phone off, so hopefully Apple will give an update so these phones can toggle better. Until then...

I’m convinced that Verizon is a common denominator based on other forums as well. Verizon sent me a signal booster which increased my service but then I realized that essentially I was just using my WiFi being that it had to be hard wired into my router so I unplugged the booster.

I have since began the process of switching over to T-Mobile and decided to randomly do a speed test and was shocked at the results. I’ve only seen 10 mbps in my home at 5 AM a few times and throughout the day it’s usually 1-2 mbps w/o the booster. Today I ran a Speedtest and 40 mbps showed up. It took close to 2 months for signal to be “corrected”.

Verizon has way too many kinks to work out for me to continue service with them.

Apple did send me a replacement phone, iPhone 12 Pro in blue, but it did not come with Verizon version, rather the open version. So I have to call Verizon to ask for SIM card. When I told Verizon my connection issue as I was activating my phone, they actives my phone differently than the normal way.

They set up my phone as SIM card plus digital SIM card. SIM card for primary and 2ndary is digital sim. I would not have the option of 5G auto, 5G or LTE anymore.

So far, it is working ok. I only saw I lost cellular bar once, but still able to receive and call.

Please see the photo and how my cellular signal bars are a set.

we will see what happened.

SAME HERE!!!! Im literally going to have to take a loss to go back to an iPhone 11 because of this garbage. I've missed so many business calls and text because of this. I have to now remember to turn on and off airplane mode every time I enter a building at my job. If I don't do that my phone has ZERO service and is deactivated. ALSO, no WIFI CALLING IS USELESS.

I swapped to AT&T and so far so good I even have 5G in some areas so I’m going to go out on a limb here and say that it’s worse with Verizon not saying it’s all Verizon but I’ll say that 5G has everything to do with all of it I actually spoke with a tower builder that confirmed that Verizon and apple was having issues with the 5G networks but since my swap with the carrier if I do loose service it comes right back like it should and overall the service is way better than Verizon I really hope they get it all fixed and soon because my bill is higher now

It isn't Apple's issue.

Cell phones have to switch to the band/frequency the BTS tells them to use; it cannot just decide to use some other frequency or it will be stomping on the devices legitimately assigned to those other frequencies.

Imagine you are driving down a road and a police officer directs you down a different road; you can't just decide to ignore them and go a different way.

I've mentioned before it's far more likely there is one particular brand of BTS gear that has a firmware issue that causes this problem and that will need to be upgraded. Different carriers often standardize on different brands, which is why people are having more issues with certain carriers, but all carriers buy from the same handful of brands so it doesn't mean that other carriers won't have problems.

If you're curious, this is the inside of a typical BTS:

Hi guys,

I had the same issue ever since I brought the new phone. It was very frustrating but

IT IS FIXED !

long strong short, after tried everything, i got an apple genius bar appointment.

it was HARDWARE issue, which I believe is the same reason for most cases here.

They replaced it for free, as all iphone 12 is within the 2 years warranty, despite where you purchased it from.

I'm not happy with the fact that my brand new phone was malfunctioning.

But at least I can use it now, hope you all get it resolved.

I am having the same issues. Since getting the 12pro I have intermittent signal/service issues. I have trouble loading sites, sending picture messages, streaming YouTube and accessing internet. Kind of frustrating. I was in the same place yesterday with someone who has T-Mobile also and their phone has great signal/service while mine didn’t. They have the iPhone7.

you should not use VPN on an iphone.

With an extremely secure Apple infrastructure why pass all your traffic through third party company?

It will cause update problems too.

You will be telling us next you have anti-virus too??

I would like to hear how this turns out. I, too, do not have 5G as an option.

I was confused by the e-sims transfer from my iPhone 11 Pro to the 12 Pro. The options were strikingly different, but none gave 5G as an option.

In any event, I am contact AT&T to see how they respond.

I've seen people report that a new SIM did not solve the issue. I was also in contact with a friend who works in the industry (with all the carriers) and he said from what he's reading and seeing the new SIM won't fix it. It's about going from one tower to another and disconnecting. One work around they recommended was switching to LTE instead of the 5G but this did nothing for me (might be worse). Supposedly they (Apple) are working on the issue but have yet to find a solution. I can't verify this is 100% correct, but I have yet to see someone who has fixed the issue with a new SIM or any other solution. The best thing you can do to recover service quickly is put it on airplane mode and then back off again. If that doesn't work I've also simply turned my phone off and on.

You do understand what a VPN is for? Its not to secure the device but to prevent ISP from knowing your every move. So yes running a VPN is acceptable. Also many businesses use VPN to allow remote access to company resources.

VPN harms, no, but if you stuck around you would see how many problems are fixed by uninstalling it.

If you value privacy why would you pass all your data traffic through someone's servers who are nowhere near as accountable as ISPs. They know where you have been too and unlike ISPs may have no duty in law to secure the data.

What country hosts the servers for your VPN?

Clearly you have no clue how VPN’s work and how data is anonymous. This issue here is not caused by a VPN. This is a greater issue as even phones with no VPN configuration added to device. By the way there is little to no difference between a corporate VPN and a VPN service such as NORDVPN. The only difference is the purpose. It’s ran on the fundamentally same technologies.

You ask what country host the servers for *my* VPN? I do not use a VPN unless I am on a third party WiFi network. If you know how networking works, this is your greatest risk. I use NordVPN which has servers pretty much every country but North Korea. Which you can set up NordVPN with no app and simply add it just as you would a private business ran VPN.

If the issue is resolved by uninstalling the app then the issue still lies with Apple and not the VPN app. But seeing that I have no VPN app and have the issue, I dispute your statement that this resolves anything.

Go spend some time learning about networking and VPNs.
