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!

The LTE signal issues with my 11 pro (Verizon) have resolved (in US). I have iOS 13.1.3 . There are some apps however, that I am unable to change the location settings in the apps, which is clearly a software issue. Before, whenever coverage is on LTE, the phone would be crippled, even with full bars of LTE, couldn't even open Google homepage. This being my time with Apple/iOS for first time ever, I'm not amused. So much for the "just works" every Apple fanboy told me.. ugh

Headed to Apple store now... call fails for 2 weeks.. been on phone technical support. Used my paid off iPhone 6S plus unlocked and was able to make one call and then straight to call fail and has not had an update in a year. my iPhone XS is locked and making payments and can’t call out but have all signal bars which I only had two bars prior.. I have ATT.., they blame Apple.. Apple blames ATT. They both about to win.. drop Att and iPhone.. guess it’s time for a Samsung... and I’ve been the biggest fan of Apple since iPhone 4. 😞😞

Well well well I don’t believe it can be fixed because it is a hardware issue maybe software tweaks by apple can make it better but not fix however due to recent events I now believe that some are worse then others. I’m on day 3 of my 14 days for return my iPhone 11 to T-Mobile and I have not had an issue yet , please everyone knock on wood , maybe I got a good one I don’t know but we will see I hope I don’t have take this back and get the note 10+

I’ve upgraded, and reset network settings, my data keeps going from fast to zero, have to airplane mode it. Still no data when on 3G. Couple of times my phone just freezes. Still no VOLTE, internet when works is slow.


my XS Max was better than this. When are we going to get a product that we paid for? So many bugs. Since Apple changed modem suppliers. Please

I’m currently overseas been in Europe

for a month now. My iPhone 11 pro max was working just fine then it stopped! It stays on no service I’ve got no data can’t make nor receive calls and I’ve just been left stranded. I’ve contacted my cellular provider sprint and they were of no use since my phone still does not work unless I’m on WiFi. Sprint refuses to unlock my phone. They informed me to find the nearest sprint store in my area! Sprint is a US based telephone provider. Please any suggestions? I don’t return home for another couple month

I have a similar issue on my iPhone 11 Pro. It's not crashing out of the sudden but when I'm at a place with no signal and return to a place with signal the phone is not dialing in again. It's showing the bars and the "LTE/4G" icon on the top but internet is not working. This very annoying as in the signal on my working place is very low. Every time I step into an elevator or go to the canteen everything stops working and phone still pretends that signal is there. Only the airplane mode can bring the internet back. I'm also on latest iOS version 13.2.3. Anyone else having these kind of issues?
