Poor signal with iPhone 12 Pro Max

I have just received a new iPhone 12

Pro Max . On my 11 Pro Max and my Wife’s XS the signal in the house is 2 bar and ok but not great. My new 12 pro max signal is terrible. Instead of the previous 2 bars I get 1 bar and calls drop constantly. Online I see others have the same issue. I spoke to Apple and they were dismissive of comments on the forum and said I could maybe return for a replacement but would have to be without a phone for a time. Very disappointing for the service they are supposed to offer. I am a key worker on call and therefore cannot be without a phone. Given other comments on here, despite Apple dismissing it, I assume it is a general hardware or software issue and not specific to me. Have others got the same issue and how do I progress?

iPhone 12 Pro Max, iOS 14

Is this happening with the 5G on or does it happen if even if you turn the 5G off? Could be poor 5G in your area if that’s the case so you might for the time being want to opt to use the LTE signal only. Not a great thing to have to do when you wanted the benefits of 5G but there seems to still be a lot of inconsistency in 5G service in a lot of areas unfortunately. I haven’t had any issues with either of the 12 Pro Max devices in my home but service is pretty strong here. Since you mentioned the signal was never all that great even on your wife’s phone (but at least better than you are experiencing) it might be a good idea for you both to utilize WiFi calling when possible too so your signal is more reliable.

You are correct millions of users around the world use their Iphone 12 without issue. If you live in a big city with mature 5G coverage you are OK. If you live in rural America or 1000's of small cities without mature 5G then those users are left holding the bag. Is it the carriers fault that the LTE section of the iPhone 12 Max sucks? No, but it is the Carriers fault for touting nationwide 5G coverage and selling these phones in areas that have poor 5G coverage. If you go back to the transition between 3G and 4G, Apple DID NOT offer a 4G phone for several years after the transition had begun. This was a Steve Jobs moniker, don't sell it till it's mature!!! Now with all the pressure to maintain market share, Apple releases a 5G phone at the beginning but develops the phone with limited LTE capability to reduce the cost. You can say it the carrier's fault all you want but it does not explain WHY an older iPhone or Android phone works fine on LTE while the iPhone 12 is a stinky pile of excrement. I can set my son's Iphone 10 and my Iphone 12 pro max within a foot of each other and the Pro Max has no signal and the 10 can make and receive calls. That points to the LTE section of the 12 is sub par. Not the carrier's fault!!!!

My internet provider is HughesNet and it’s fine.

mMy issue is the phone signal with calls, texts, and data.

all older iPhones (7plus, 8plus, and XR) work.

My 12 has call failed, dropped calls, won’t send it receive texts, and no LTE (let alone 5G live rural… not expecting 5G to work except when in areas that provide).

Verizon is our carrier.

Bought phone at Best Buy under my Verizon info.

New sim.

My response wasn't to you on the 5G. My tech told me it may be 5G and to turn it off. It was already off because of what has been tested in these forums. My Apple tech ran diagnostics on my phone and found numerous dropped calls. AHA! Apple knows there is a problem!

Second, Excuse me for using the term 'boost'. I understand completely how Wifi calling works. You can still have connectivity issues with Wifi calling depending on your Wifi set up.

Third.. I don't know if you work for or are commissioned by AT&T, but they too are having problems with their iphone 12's. As I stated in another post, you are one of the lucky ones. Perhaps it's where you live? I don't know. If you still think it's only Verizon having issues Perhaps you should check At&T's support page, you would find a lengthy forums on iphone 12's lackluster performance. Perhaps you should visit any other carrier forum and check for i-12 posts! Forbes ran an article about the thousands of users complaining of the phones performance across all carriers, or lack of performance in this case. I was an At&T subscriber for 25+ years until they let their infrastructure go in my somewhat rural area. We all have opinions. Some of us are here because we have problems with our iphone 12. We know we can't compare apples to oranges. No, you can't compare a Corvette to a Spark. Regardless of which model you purchase, you expect it to work. Changing to AT&T is not the solution! Changing to any other carrier is not the solution. Good to know you have ZERO issues on At&T. Why are you even responding if all you can say is "Change carriers" or "Sell your phone"? We have read it. It's comparable to throwing the baby out with the proverbial bathwater.

Numerous dropped calls does not necessarily indicate an issue with your phone, you will see the same issue if your carrier is having issues, as in this case.


AT&T's forum means little to me as I have an iPhone 12 Pro Max, and fellow employees at my company have literally hundreds, and none of them have performance or signal issues on AT&T.


If Verizon refuses to fix their network, what other solution would you advise? It's not the phone, and Apple can't force Verizon to do anything.


So you are then left with only the things you can do, which are:


1) Change cellular carriers

2) Get a different device


Now I know Verizon is fixing it on some towers over time, so there's always possibility #3, call them on a regular basis to complain.


But if you need a solution today, the only answers are the two I listed.

Could you please direct me to a post where someone having an issue with AT&T has been directed to switch to Verizon?


For that matter, how about where a Verizon user was told to switch to AT&T?


I have said that the vast majority seeing these issues are Verizon subscribers, and that to resolve the issues you may need to switch carriers.


I've also said the vast majority of AT&T subscribers have not seen these issues.


However, there are more than two carriers extant.

It's not Apple's issue, it's your cellular provider.


Millions of users around the world have the same phones with no issues whatsoever.


Admittedly, many of them are on AT&T, but some AT&T users have seen issues as well.


On numerous occasions users who did have these issues had them suddenly disappear when their carrier made changes to a local tower.


Apple won't issue an update to fix this because their devices aren't broken.
