iPhone 11 Pro Max 4G LTE Signal Issue

Same issue with my iPhone 11 in France. The weird thing is that data don't work only in the area where i usually get a strong signal reception with my former iPhone 6s. In area with 1 signal bar i don't experience any 4g drop.

Some users seems to have the same issue here :https://forums.whirlpool.net.au/thread/35q48kw3?p=5

I am due to change my sim card tomorrow.

However i have had no issues with data till now on my iPhone 7!

I have maybe restarted the iPhone 11 Pro Max 10 times today. Seems to be that the more you use data, the quicker the data connection drops - although still showing 4G!

Apple fix this!!

I was in Indonesia for 2 weeks and was using Telkomsel (GSM) with No issue. But it was running iOS 13.0

as soon as i got back to US, the issue occurred.. ( iOS 13.1 carrier Verizon) even after I disable VoLTE, even after i swap SIM.

my friend who sits next to me at work has same carrier, and same iOS version, but using iPhone X has no issue. So i dont think it’s carrier/network issue.

then I Updated to 13.2 Beta, carrier Verizon. The problem persist.

Signal receiver and iOS compatibility issues with CDMA ..? (i assume)

Now my iPhone Pro max running 13.2 beta with TMo (GSM) No issues.

While on LTE (Verizon) in the US, even with full bars of LTE, my new iPhone 11 pro with update 13.1.3 is almost useless. I can not even open Google webpage and txt barely works. I did not have this problem with my Google Pixel devices like this. I switched to iPhone for the first time ever in my life and I'm beginning to think I should not have. :( Will this be fixed?

I’m same situation 256GB on Verizon my reception is horrible I’ve called and spent countless hours w tech support I can’t figure it out. Have you figured it out? I’ve gotten a new SIM card and all still same thing?

Same issue in Germany on Vodafone (which has one of the best reception here). iPhone 11 Pro, iOs 13.1.3

First I’ve thought this was my old SIM card so I’ve removed it and installed an eSIM profile. Same result. Barely 2 lines of 4G while in the middle of the city where my Goggle Pixel 3 has full coverage. Sometimes even if it shows full 4G bars, there is no actual data connection. Rebooting the phone or cycling the eSIM profile On/Off does the trick for about 30 seconds and then is gone again.

I too bought a new phone, full payment, identical model iPhone 11 pro max 256g space gray, unlocked from Best Buy. Popped in my same old T-mobile sim. So far NO ISSUES. Definitely points to a bad batch of phones.

Still waiting for my down payment refund from T-mobile for the returned defective phone(3-5 business days). All the promises from T-mobile about honoring the trade in credit for my original iPhone 7 Plus until they could send me a replacement turned out to be bogus. The remaining question to be answered by T-mobile is how will I be made whole with respect to my old trade up phone which they have? (“Will have to research and get back to you within 72 hours”)

I was trying to get by on an old Android phone until T-mobile “got more in stock” After 4 days could not take it anymore.

I honestly don’t think it’s a batch of phones. If there’s anything I noticed with my issue, it is particular locations where the problem is consistent, where other areas are completely fine. I’m located in Australia, on the Telstra network, and was made aware of location based changes/updates where this issue seems to be apparent.

If the problem was hardware/batch related, the problem would be constant, which it isn’t.

I’d say most people experiencing the issue and feeling like it is a constant problem - is most likely experiencing it at regular locations like home or the office/work.

Sorry, but I must disagree. I do not think you can rule out hardware. I had the same symptoms in the mountains of western NC and in the middle of the city of Atlanta, Georgia, 130 miles away. The replacement phone I obtained yesterday, using the original T-mobile SIM, so far, has no issues.

I think it’s software. There is many users reporting the same behavior with previous iPhone version as Xr, 8 or XS with iOs 13. Also as pmmalg said the issue seem very location based so it’s probably more software. If it’s a hardware issue it’s a problem with a particular mode of the modem so maybe a MIMO issue or a problem with a particular frequency.

Some users get the problem even with their replacement phone.

Since the day I got my 11 Pro Max, I’ve been unable to get LTE (or 5GE, as AT&T calls it) almost anywhere. In the rare instances that I do get a connection, as soon as I enter a building, it’s gone.

My first step in trying to resolve this was to call AT&T, but they immediately told me that they had already gotten “thousands” of calls about this issue with the 11. He didn’t specify Pro or Pro Max, he just said 11, but “thousands” was the word he used, which I’m assuming (hoping) was hyperbole. He said there was nothing they could do and that I needed to go to Apple.

I brought it to the Apple Genius Bar and they replaced my SIM card, but that did nothing. So I made another Genius Bar appointment, and they replaced my phone. I’m sorry to say, however, that the new phone has exactly the same problem.

In cases where I really need to use cellular data (because there’s no Wi-Fi available), I turn off Enable LTE in Settings, but that works only slightly better. Then, after a short period of time, it no longer works at all, and I have to restart my phone.

So I made yet another Genius Bar appointment, but the person with whom I met basically blamed it on AT&T and said I need to deal with them. (I pointed out that that’s where I began, and that they sent me to Apple, but that meant nothing to him.) He claimed that he wasn’t aware of this being a widespread issue. I pointed out that there are additional pages dedicated to it on the discussion forums every day, but he completely dismissed that.

So now I have a $1,600 phone that only connects to data on Wi-Fi.  I’m going to wait until iOS 13.2 is released and, if the issue persists after updating, I’m going back to the Genius Bar and demanding a new phone (the last guy I dealt with wouldn’t even consider it), since some people have seen the problem resolved with a replacement.

I bought the original iPhone, and I’ve upgraded every year since. I’ve never had a major problem like this with any prior phone, so this situation is extremely disappointing, to say the very least.

It is not the carrier as people with a variety of carriers are having the same problem. My carrier is T-mobile. That said, 13.2 is still beta so I am sure Apple would not help you if you had an issue. I got a replacement unlocked phone from a retailer rather than T-mobile running 13.1.3 and have no issues. Using the same SIM as well.

How did you get your phone replaced, I have been trying to do it since 3 weeks but still apple genius bar keep refusing to do so or at least to be accepted as a hardware failure instead they said it is related to my carrier, and we are not responsible for that, really finding my self with a phone costing over 170,000 yen which is 1600 USD with a continuous need to be rebooted at least 5 **** times by day, Apple what the heck are you doing ????????????

I have 13.1.3 and, whenever Verizon gets into VTE coverage (from the regular) my iPhone 11 pro gets pretty much useless.. sometimes makes a call, sometimes will do a txt but ify and super slow and things won't work, like GPS gets all super wonky and thinks I'm in places I'm not. Google assistant is crippled and won't work on LET, at all, and thinks I'm defaulted to my home location 100% whenever on LTE. This is my very first iPhone ever and i am NOT impressed in the slightest. I hope this gets fixed, or I'll bounce out of using Apple products and back to other company's products. ugh.

The crappy LTE signal is not carrier related it the fact that apple has to use the Intel modem, they are terrible and no software update can fix it its the hardware. I am hoping for 2020 iPhone to have qualcomm modems
