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 have connectivity issues too with my 11 pro max. I live in an area with spotty connection but it’s much worse with the new phone versus my old XS Max. Upgrading to 13.1 did not help. Switched the SIM back to my old phone and it works just fine. Super frustrating.

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 the same issue with a new Iphone 11. The problem has been there since I started using the phone, which means that I have never been able to use cellular data on my brand new iPhone. As soon as I try to use my 4G network (the carrier is Tele2 in Sweden) I lose all bars, after about 2-3 seconds they return. The problem appears regularly. At the same time, older iPhones work fine. I have been in contact with both Apple and my carrier for what seems like endless phonecalls and suggested fixes from Apple that have not worked. Moreover, they both blame each other and fail to take responsibility for the problem.


I was surprised to find thread today, as Apple continuously have declared that I have a very strange issue that they have never heard of before.

I’m using the latest updates, still have problems with iPhone 11 Pro Max keeps crashing, voice calls keep disconnecting, 4g data failing to work correctly, VoLTE does not work anymore, network speeds are very slow.


why is it my iPhone XS Max was better and faster and had no issues, even when I was beta testing ios13.


i think its an hardware issue to do with the modem changes, as they swapped from Qualcomm to Intel.

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?

I now have a new issue, I loose the 4g or 3G symbol but still have data... I am using three in the U.K. and am running the latest iOS version... also I am still using 3G rather than 4g with VOLTE... also my battery life is not that impressive... having to charge daily as I can use about 40-50% battery within a day... which I think isn’t good...

I am using ios 13.3 public beta latest version. Till have the same issue on 4G FDD-LTE & TD-LTE (2300Mhz) sim AND 4G GSM sim SAME TIME. Till the phone struggle to give a stable of effective signal. When the 4g signal down and regained, the device failed to gain signal automatically. Many times it need turning on and off the airplane mode to get data again.

i think this should be a hardware and software combined conflict. Apple have the ability to sort this out itself, not depending on developers for these kind of Critical issues. dear apple, please look in to this matter and provide a solution. Otherwise recall the devices and replace the devices.

Can you check which version of iOS is installed?


Was digging into the issue and noticed my 2nd Pro 11 on Verizon was on 13.1.2. No software update showed as being available so I assumed I was on the latest OS. Looks like the issue we are describing was supposedly addressed in 13.2.2 according to release notes. I just upgraded my Pro 11 from 13.1.2 to 13.3 beta 4. Will report back.

Can confirm that my issue appears resolved in 13.3b4. I can replicate issue by going into area with no LTE and when I go back into area with LTE, data immediately returns. Previous behavior was that data would not return automatically and would sometime take up to 90 minutes if I didn’t manually reboot phone. Had a couple of long calls since update and no dropped calls. Note this is compared with 13.1.2.

I’ve had a new iPhone 11 Pro Max in the U.S. on Verizon for 10 days. I transferred the SIM card from my old iPhone 7.


This phone is intermittently losing LTE network connectivity even when it shows four bars. The network will drop for about 20 seconds, then return for a few minutes, and then drop again. Doing anything away from WiFi is frustrating: streaming music, doing any kind of search, buying things...anything that requires network is completely unreliable. I’ve rebooted multiple times.
