Poor signal with iPhone 12 Pro Max

Alright, thank you for the technical explanation here! Is there a way I could restrict my phone 12pro max to always use 3G or just 4G bands and not the 4G-LTE ones to avoid falling trap to this Band 28?

This was, at least I could test and see if the call drop does not happen on the 3G bandwidth.

Sadly no, that's all done by the base controller.

If the culprit is 5G and you have 5G on your account, you can try turning it off to see if that improves things any, otherwise there may not be anything you can do.

It's also not specifically Band 28, that's just an explanation of what the problem could be and how it's very possible for it to be an issue with the 12 Pro Max but not because anything is wrong with the 12 Pro Max.

Well, still hard to believe actually and forgot to mention in my first comment, I had travelled abroad with both the phones and faced the same issues in other country as well. This was documented in my case with the apple representative thus prompting them to schedule my immediate visit to the apple service center.

To your speculations of issues with BTS or towers in the local region, any configuration issues with the configurations at BTS stand global to all the frequency Bands and not just the one unless the transceiver itself is faulty which would be a bigger concern for a service provider than just dropping calls on my iPhone 12 pro max.

I'll go ahead and try the reset and reconfigure and see if it helps.

Your assumption that a base station issue would be common to all frequencies or towers is not true.

For example, if there was a bad cable to one antenna on a tower, that would cause phones that communicate on those frequencies to drop.

If you've seen issues on multiple towers, it could also be a configuration issue, or a bug in one particular brand of base station controller.

Good luck with the reset.

I was an Android phone user. never wanted to switch to iphone. This is the first time buying iphone 12pro max and totally disappointed. The signal reception is very bad. My old phone used to connect well to the wifi even outside the house. But the iphone is not able to connect when upstairs or at the kitchen. The WhatsApp call is flickering and the caller was telling my voice was breaking through out the call.

and the charging takes a lot of time.

iPhones sell for a good price on eBay and then you can buy another Android… problem solved.

It’s not a snarky comment - obviously aren’t going to be happy with your iPhone so why put yourself through that?

No one product is right for everyone’s needs, that’s why companies offer a choice.

For this price expected a bit more. The basic use of a phone is to make calls . This is more like an ipad now. One plus 9 pro is much superior phone than this . I might switch to one plus . One plus charging is super fast and better life is amazing.. the battery., signal reception, camera and accessibility all better in one plus. I made a mistake choosing this iphone🤦🏻‍♀️Never buying iphone again

Fair enough.

My 12 Pro Max is the best cell phone I've ever owned, it has not dropped a single call since I got it in November. Unlike past iPhones that dropped calls in some known areas, the 12 Pro Max has been absolutely perfect.

Buy what you want; Apple is not here, we're just Apple users so you can purchase whatever you like and it doesn't affect any of us.

Not here to convince anyone, neither of my telecom engineering nor of my work experience in the communications field. 🙂

Thank you for your valuable time and helpful suggestions! Your inputs made me realize that all the towers of all the CSPs around the world needs an update but iPhone12Pro Max that I own can never be at fault.

Thanks for the enlightenment!

You, apparently, are one of the lucky ones. I've had issues from the beginning of this iphone 12 pro max. I thought it was everyone else (on the dropped calls), but when people tell me daily they tried to call and couldn't get through, I began to realize it was me and this phone. Perhaps it is a Verizon tower issue, but when I read everyone is having the same issue with different carriers, It's definitely the phone. An iphone XR sitting beside mine can have 3 bars of service, while I am barely hanging on to 1. I can't wait for an upgrade. I am an Apple person, but this is by far the worst money I've ever spent!! I actually hate this phone. I spend my day returning calls and apologizing for dropped calls.

I went to a Verizon Corporate store and they installed a new SIM card. It’s only been a couple weeks, but I actually had cell service on my trip to the Oregon Coast. I am hoping this will fix the the problem.

Not one of the lucky ones; hundreds of my coworkers alone have no issue with theirs.

I've explained several times why you would see a different signal strength, and quite frankly almost zero AT&T customers see this, almost all of them are Verizon customers.

If you hate it that much, why not sell it on eBay for a nice price and then get something else?

Life is too short to be continuously frustrated by a product that doesn't work for you, even if it's Verizon's fault.

i don't think it's issue with Verizon . I don't live in USA. Iphone 12 pro max wifi signal reception is very bad. my phone works only in the room the wifi router is kept. When we leave that room, signal is lost. But even the old cheaper Android phones works very well even outside the house. This device drives me crazy. It works well only with high speed full signal internet. I have to sit next to the wifi router to use this phone

That's an issue with your WiFi router.

I have no issue using any WiFi router I choose in any location, and these routers are not "in the same room."

In fact at present I am a good 500 feet away from my access point with lots of intervening walls and my 12 Pro Max does just fine.

I live in Canada and have same issue with iPhone 12 Pro Max. My friend uses a different cell phone provider same problem. The antenna sucks, while you are driving it can’t switch from one tower to next. No reception, people can’t hear me. Tried everything, I have tower at end of my street and can go right underneath it and poor quality reception. Tried 5G LTE everything. 4 new SIM cards. No help from Apple. It’s a piece of junk, maybe the people who aren’t having problem received a different batch manufactured lot number. But I have a lousy one. I took my SIM card and placed it in my old 4 year old or more Samsung. Guess what no issues. No dropped calls no reception issues no issues while driving. Clear reception. Apple needs to address this issue and not ignore all of us who are having similar. problems. My friend gave up and purchased a different new phone. I’m going to revert to my old Samsung while trying to deal with Apple. By the way I have Apple Care , I will be trading in this piece of junk as soon as new phone comes out. If it’s an other problem I’ll go back to android. Dependable to run my business. Apple iPhone 12 Pro max 256 memory isn’t. I’m wondering if it’s got to do with memory, my friend also had 256 memory. Maybe these are the bad ones?
