iPhone 11 Pro Max 4G LTE Signal Issue

The new iPhone 11 Pro Max loses 4G signal from time to time (every a few minutes) when the Wi-Fi is off or no valid Wi-Fi hot spot is nearby.


Wi-Fi is off: The 4G signal drops to null in a sudden, and restores to full (4 bars) in 2-3 seconds. This happens regularly.

Wi-Fi is connected: The bars are steady - stay at 4 all the time.


I have tried:

  1. Disable Auto Network Selection
  2. Reset Network Settings
  3. Reset All Settings
  4. Reset All Content and Settings


None of them shows promising improvement.

I just got back from Apple Store and they swapped out my phone for a new one and the problem was fixed!!!


I would suggest doing these steps first before you go to Apple Store:


1) Call your cell company to debug first. Apple is going to say since it’s cell service issue and it’s not Apple problem. Cell company is going to go through list of debugging issues (reset network settings, etc) to see if that fixes your issues. If that doesn’t fix, continue debugging steps below.


2) Do a screen record of your phone dropping the cellular connection as evidence of you having issues just in case you’re in the Apple store and you can’t reproduce the issue.


3) Backup your phone. I used my laptop to backup because it restores much faster that way than going through WiFi.


4) Do a full wipe of your phone and set up your phone as a new phone (don’t restore from backup). This way you can see if your cellular issues are from software or from hardware.


4) Test our your phone and see if you are experiencing same issues.


5) If your cell connection is still dropping, take it into the Apple Store.


Good luck! I feel this is for sure a hardware issue for most people!

если у Вас версия 13.2, сделайте даунгрейд до 13.1.3. Если не помогает то в 13.2 единственное на сегодня решение сбросить настройки сети и выставить принудительно использовать 3г сеть. Проблема софтварная, ждём скорого фикса.

я участвую в бета тесте, инженеры аппле связывались со мной и просили логи моего устройства, так что явно работают над фиксом.

Here’s my story: I purchased an iPhone 11 Pro Max 256 GB Midnight Green on 9/20/19. My carrier WAS Verizon. I had horrible reception from the beginning. The reception was the worst in my home. Mind you, I live 20 mins away from Manhattan, NY. Shouldn’t I have great service? Especially with Verizon? Fast forward, I spent the better of a week and a half calling Verizon tech support. They reset my number on their end. I wiped my phone three times; only once restoring it from a backup. It was until this passed Wednesday that I had enough. I called Verizon customer support to have my phone exchanged; I forgot to mention, I also took it to Apple to have it check out before the exchange order. The rep submitted my exchange and placed the order for me. Twenty minutes later, I receive an email from Verizon fraud and was asked to call. I called them. Everything went down hill from there. They wanted a photo ID, in which, I had no problem sending a copy. However, they wanted one more additional document, and that is where they went **** crazy! They were requiring either a car registration on my name, a utility bill, or voter ID card. I’m sorry but I don’t have none of those things under my name and I don’t have a voter ID card (I’m a registered voter nonetheless). I offered to send them a paystub, bank account statement, U4 (I’m in Finance), or my student loan statement. They were not willing to take any of those documents I offered. All in all, F U, Verizon! I left that sorry company. I am now on AT&T with a brand new iPhone 11 Pro Max 256 GB in Midnight Green and I am LOVING every moment with this phone. It is now, PERFECT! F U, Verizon! I dodged a bullet! Thank You, AT&T!
