iPhone 12 Pro iPhone 12 Pro Connectivity Issues

I think it is very simple: if the issue is not resolved within the 14 days return period, then the 12 goes back. Assuming this issue is wider than the few posts here, that will send the right message.

There's quite a few reddit threads (including the one I linked in the original post) that have at least a couple hundred users reporting the issue. Also, who knows how many other people are having this issue that don't know about MacRumors or Reddit etc. Even if it was a few hundred people, sure that isn't an overwhelming majority but there is something to be said about the severity of the issue. Where exactly do you draw that line?

Think about this: you're driving home/waiting for an important call/text and you don't even realize that your phone has lost service (in an area with perfectly good service) for completely no reason. You only notice by the time you get home and it's too late... The only solution so far is to restart the phone or toggle airplane mode, which isn't great. Those calls are still going to be missed. I've missed a handful already from friends.

Then you go to Apple/Verizon/AT&T etc (and many of us have done this/let them know). They are deflecting on one another, the support agents have no knowledge of the issue. Apple (at least to me) claimed engineering knows about it, but that's all I got. Nothing about what the issue actually is or at the very least when we can expect it to be fixed? Is it an iOS update, carrier update etc.

A lot of people rely on phones as their sole form of communication & for one of its most basic features to stop working for no rhyme or reason is not great. Having a publication actually write about this issue would at least bring this issue to the top of the pile and possibly have it be publicly acknowledged by the parties involved.

I'm not being facetious but what other steps would you take? The only option at this point is return the phone, and frankly that's a terrible one.

also important to have service for someone like me who is a healthcare provider ON CALL. It’s unacceptable. NH here.

Same here. Switched to eSim. And so far, so good. Not in 5g area so not sure what eSim will be like in a 5g area, but at least I’m keeping connectivity so far since switch.

UPDATE: was on eSim and it did not fix. Two days ago, switched back to original 5G Verizon sim that came with 12 Pro, Verizon needed to “refresh the sim” or something in their database cause when we first tried to activate it said it was unavailable for use.

Also, at same time updated my plan to their newest 5G unlimited (though not convinced this was necessary). Took about 45 mins for phone to activate on physical 5g sim.

Once activated it dropped completely again to ...No Service after 10 mins, then it came back to service (2-3 bars consistent with the LTE service I typically get in this area) and it did this twice more in 25 minutes.

I left it all night (7 hours) with WiFi off and connected to cell (again, I’m not in 5G area) on LTE network.
Since this, I have experienced what I would call normal connectivity on the LTE Network. The phone has been with me at all times, getting 2-3 bars in my home and have not had a drop yet.
I have not done a lot of driving around though even during my few short trips it stayed connected. Even prior it was dropping a lot even just sitting at my desk before. I realize I changed a few variables at once, but I’m suspect that there could be some merit to the sim refresh update step and leaving it connected to Cell only and possible tower software updates that the carriers are likely still running for us non5g people connecting to LTE hardware with 5g SIM cards.

I hope this helps someone. :)

I woke up this morning to my iPhone having 38 new text messages (non Imessages) from Friday. I thought that was kind of weird and not sure if they are working on this issue and maybe that was a underlying issue thats related or not.

I'll add to this. I haven't done anything in particular but I haven't had, to my knowledge, a drop to no service in about 48 hours give or take. I've been trying to keep off WiFi and monitor my phone frequently.

Edit: Of course after writing this post it happened again while trying to run a speed test...

Spoke with an Apple Advisor this morning. He uploaded cellular logs data , via Apple’s Support App, in order to send to Apple Engineering to make sure Carriers are up to date on their end with an authorized carrier update to support iPhone 12/Pro...

Seems odd ALL carriers ^ mentioned in this thread are in of a carrier update, or the baseband 1.00.03-5, or in need of BOTH!

You got me excifed. I’m on that baseband and still having the issue. Le sigh.
I DO remember YEARS ago having to go to my iPhone settings —> about to get a “carrier update” that just popped up. I am hoping that’s all they need.

I have also noticed that I generally have 3 to 4 bars of service at home but with my 12 Pro, I only have two.

I have an iPhone 8 Plus that has 4 full bars, it makes no sense. How could the 12 Pro be getting worse reception than the 8 plus?
 
This thread confirms my dread about first iteration of 5G in an iPhone. I had two different 5G Android devices I returned because not only did they get exceptionally hot, battery died quickly, but they had major issues with signal on both AT&T and T-Mobile.
 
I did a full restore to 14.1 and still was having issues. Since Friday, I have been dropping signal 10+ times a day. Today, it hasn’t dropped yet. The phone is in the same spot. Co-worker got a bunch of texts at 1am that were from the previous day. Fingers crossed that AT&T updated something and fixed it.
 
I've been driving the same route multiple times the past 3 days. It's been very predictable where I will lose service (when someone else in the car using an iPhone XS will not experience issues). This afternoon was the first time that my 12 Pro did not lose service, so I'm wondering/hoping the Verizon is working on it. Like other posters here and on Reddit, I'm in the Boston area

Has there been a carrier firmware update?
 
I'm on tmobile and have fewer signal bars than normal almost everywhere. LTE/data seems fine. I moved from an 8 plus and put my sim into the new phone. maybe I should activate the new sim and see if that helps, but my 8 plus never had an issue on that sim.
