iPhone 11 Pro Max 4G LTE Signal Issue

Same ****... with 13.2 problem is all the time. I reported about this issue in Apple beta Feedback app, and Apple team already answered to me that they need additional files from my phone. I send all files, so waiting for fix maybe in next beta.

I think problem is in new modem firmware in 13.2.

I am having the same issue on my EE iPhone 11 Pro max phone. I have tried everything, reset the network/all settings, turned airplane mode off/on, turned the phone off/on, reset the phone to factory default without restoring the back up. Still it does not correct the problem.

The data signal just drops and the connection is lost, then it comes back on again after a few seconds. This happens every few minutes during my chats and data calls.

13.2.2 did not fix this for me. Despite having a T-Mobile signal booster in the house, which provides a strong LTE signal on band 66, sitting 2 feet from the signal booster the phone connects to it and I get 4 full bars, fast data and everything works perfectly. About a minute or two later, it will inexplicably revert back to the weak 1 bar LTE signal I get from the actual tower, with slow or no data speed. Sometimes it will eventually go back to the strong signal from the signal booster, other times it stays connected to the weak tower signal forever. I paid $1200 for a phone with no cellular functionality.

Even after 13.2.2, its have small issue.

but now i activated beta testing mode and feel better on coverage. But band 40, 2300mhz fdd-lte shows non active signal bar. But the sim is working.

when we use gsm call, the data from both sims droped.

hope apple will fix with serious mind.

IPhone 11 Pro and two brand new 11's all suffering from this. Two different networks.

Old 6s worked fine throughout my house, new Pro drops calls constantly. Same story for the 11's at a different house and different network.

Apple please address the issue!

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 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.

Everyone has the same issues. Not the networks obviously. I have a 2 week old 11 Max on T-Mobile running iOS 13.3 and I’m having all the same issues. Took it to the apple store at the Mall of Georgia and they were worthless. I walked down to swap the sim at T-Mobile who were helpful and it didn’t fix it either. I have 2 days left to return it or get a different phone. Is signal better on the regular iPhone 11? maybe go back to an old iPhone or back to a Pixel.

I’m having serious connection issues as well, my wife can be right next to me with her iPhone 8 with 3 bars and mine with barely have 4g, constantly loses connection! I cycle airplane mode a dozen or more times throughout the day and that seems to help but it’s temporary. I’ve power cycled the phone, reset the network connection you name it to no avail!

The phone had no issues for a month and then in the last few days the problem has happened again. Today I was in an area where I had three bars of LTE but every app and browser reported no internet connection. Switching to airplane mode and back again did not fix. When I moved to a new location with four bars I still didn’t have any internet, but from there I switched to airplane mode and back again and now internet service is restored.

Bruk999, when that happens, if you simply turn off WiFi does it the browser work? I’ve been having this issue off and on and sometimes turning off the WiFi helps things like browser to work. However, it still NEEDS to be fixed.. just wondering if that is same on yours too

Whatever fixed it in one of the betas (I think it was 13.4.1), I’m sad to share that the issue resurfaced in the latest (I think either 13.4.3 or 13.4.4).

Now I’ll schedule an appointment with support and demand a new unit.

It is definitely a design flaw in the 11 Pro Max. I jumped ship after a week of owning my it. First to the 11 and it worked fine. Now I’m on the 11Pro (not max) and it’s perfect. No issues with reception at all. Apple should have to address this, but I honestly feel like they will just move onto the 12 and forget this.

After to complaining to everyone about how my iPhone 11ProMax is absolutely the worst cell phone I have ever owned in 20years I decided to have it replaced. (My kids call it my iCamera because at least the camera is amazing!)

Apple support was, as always exceptional and two days later I received my replacement phone.

I have to admit it is better, but just marginally. Calls are still very choppy and what's really odd is that it will show four bars and the second I make a call it drops to one or two. I hang up and it's at four again.

I vaguely recall, but can't find where someone mentioned a setting in the cell phone setup where you can maybe turn off LTE or something like that?

Anyone have any ideas?

And I will be 110% replacing this as soon as the iPhone12 is available. I assume that's what next week's announcement is about.

I upgraded to iOS 13.1 about 2 days ago and issue did not get fixed. I believe it’s my chimney which is pure concrete I believe. Not even bricks.
