Poor Phone Reception on Iphone 12 Pro

I have had issues with my iPhone 12 Pro Max from day one and blamed the call dropouts on the 3 Network i was on. They sent me a new sim card which made no difference. I could be speaking to someone and be stationary say at my desk and for no reason the other person cannot hear me but i can hear every word they say crisp as anything. I move into another room and sometimes that helps although the call is on wifi so should of helped anyway. Sometimes calls received go straight to voicemail so i miss them totally as the phone doesn't even ring. The callers are not blocked. I changed to EE and experienced exactly the same issues from inserting a brand new sim so i know its the phone and not the network provider. We have 2 iPhone X in our family as well and they experience no issues what so ever. Spoke with Apple today and they agreed to send me a replacement phone but i had to lay out £1199 before they would post it out. Yes i know they charge this as a guarantee to get the phone back but having applecare plus as well you would think they would send another one out next day courier and collect the defective one at the same time but no. What really annoys me is that we are the guinea pigs for these big companies who cant get their products right before selling them to us.

I just went into my Cellular settings and changed my Voice & Data from LTE to 4G. I went from having 1 bar to 3 and 4 bars. The pones must default to LTE

Hi. Hope this helps. The reception in my home is also poor so I use internet phone setting - phone - on. Then, instead of using 4g, change to 3g settings - mobile data - mobile data options - voice and data - switch from 4g to 3g. I don't know why it works better - but it did for me. Hope that helps, thanks

Hello, I just purchase 2 Iphone 12 pro max 256gb on Dec 3. I am having the same issue. I took it into the Jump Plus store and they basically did nothing. I tried switching service providers from Fido to Telus and then back to Fido but still the same issue. Here is what I did to resolve the issue,

Open settings

Select "Cellular"

Turn off "Cellular Data"

Select Cellular Data Options"

Select Voice & Data and pick the 3G network.

Doing this gave me full bars within a few seconds and it is still working well.

Hope this helps, please let me know if this works for you.

I had the same problem with my iPhone 12 max pro, kept getting no service or 1 bar whereas my Xs Max always had 3 bars come to find out it was my magnetic phone case that was causing all the problems, switched to a leather case now I consistently get 3 bars.

So I have been fighting this issue also. While I am not at 100%, I found that a Speck clear case caused a 6 db to 8 db drop in signal strength. If you type "*3001#12345#*" and hit call. It brings up a testing signal app. I was able to use this over a few days of testing to find the signal variations. I submitted a warranty claim with Speck, and they are sending me a new case. I think all of this has to do with the iPhone 12 not having a dedicated 3G antenna. Looking at the signal info, it is different from an iPhone X that I was comparing it to. Apple said Verizon is working on a fix and I saw 14.4 beta has modem updates also. I now have the otter box commuter case. It works as well as no case, signal strength wise.

Come on Apple we are paying good hard earned money for crap products!!!

So what is the fix and is it just on the 1st batch of phones released or does it apply to all iPhone 12 models with 5G?

Too many others are experiencing issues so be honest ....... (as if)

Go into Cellular settings and switch from 5g to LTE . This worked and I now have full bars.

I posted on this back in November, the 12 Plus is garbage and apple has yet to update us with a fix. I ended up shutting off the 5G and I’m just using 4G with LTE on Verizon network. The phone got better, can actually take and receive calls now, but the quality isn’t that great. Wish I kept my 8-Plus, best phone I’ve ever owned.

At the direction of apple support, Under: Settings/General/Reset/Reset Network Settings.

This seemed to work for fixing dropped calls while on my 15 mile commute today.

Hopefully not just a coincidence or lucky day.

Device: iphone mini on ios 14.3

Lol... I went through a bunch of cases myself trying to find a case that least interferes with reception. I've ended up using a slim tpu case that doesn't feel great but it's a compromise that I am willing to make for functional reasons.

I had the same problem, however do you have a phone case on ?

I feel When I have a case on it does that

iPhone 12 pro max seems to be experiencing strange drops in service in places where I have previously had service with my Xs max. I’ve experienced it inside my home and also outside where I lose all service until I restart the phone. Once I restart the phone I will gain service.
