iPhone 11 Pro Max 4G LTE Signal Issue

I am on xs max but ha e all the described problems since I got the phone. Installed 13.2.2 Wednesday and have absolutely zero issues since. Hallelujah! It's finally how it should if been all along.

Hopefully they don't ruin it in future updates like they have before.

Dear All,

the issue of bad service finally was fixed. What i did is that i reseted my

iphone regarding service factory settings while at the same time i contacted my service provider to reset 4g settings. Everything works fine now. You have to try it.

I have the iPhone 11 Pro Max 256 GB in Colombia using Movistar. Similar issue, I tried everything suggested around the web: network settings reset, phone reset, changing from regular SIM to eSIM, going on beta then going back to a regular release and so on. Nothing seemed to work.

From what I could gather the issue occurs more often when you enter a zone with low signal strength, the phone then would drop signal entirely, not being able to recover by itself, making me miss important calls, messages, notifications and so on for whatever time it was off (sometimes I would notice minutes or hours later), what would fix the issue was putting the phone into airplane mode then switching it back or a simple reboot, only then I would get all the missed calls and messages notifications.

I decided to try my luck once again before scheduling a support appointment with apple resellers in my area, so I re-enrolled into beta, to my surprise there was a new version iOS 13.4, installed it a few days ago, and boy, oh boy, I haven't seen the issue occur since then, keep in mind this usually happened around my house all the time, not some random place I rarely visit.

Hopefully this means apple is actively looking into this problem and trying to address it properly.

I wish this information can help some of you folks with a similar issue.

Regards.

No. T-mobile. And they are replacing the phone whenever some more of this model comes in stock since I submitted my issue within their 14 day grace period.

Update. After lengthy call with T-mobile and conferencing in Apple the end result is that T-mobile is going to send me a new replacement phone. The only problem is that the iphone 11pro max space gray 256g is on back order till late Oct or early Nov. The T-mobile buyers remorse window is only 14 days. After lengthy discussion with T-mobile rep ( who was completely sympathetic and supportive) she worked something out with her supervisor to 'override' the retrurn window policy so I can hold on to the flaky phone until the new one arrives. Hopefully, the replacement phone will come from a new lot and not have this issue. Apple, on the other hand of little to no help. They offered me to send in this phone for repair or replacement with no thought of what I would do without a phone while they were analyzing. They did note the existance of this thread and did not push back, which says to me they know there is some issue. I have scanned the tech press and seen nothing on this yet.

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.

The replacement 11 pro max 256g unlocked I obtained from a well known USA blue and yellow retailer is working perfectly for over 2 days now in different cities. Someone else on the thread said IOS 3.2 beta solved their problems

На примере Латвии, ошибка была в конфигурации сети мобильного оператора. После того как LV LMT поправили настройки, LTE в телефоне заработало, даже не нужно было перезагружать телефон.

у меня iPhone 11 Pro Max 256Gb, iOS 13.2

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.

Having Apple Care or not is irrelevant, all iPhone 11 Pro Max are still covered by regular warranty, also read different post from people in this same thread where they explain how taking the phones to Apple Service didn’t help at all, not even when they got a new replacement.

The issue is most likely firmware/software related to the “new” Intel network chipsets. Which is why I suggested updating to beta 13.4+, this is something that apparently fixed my issue (similar to yours), not something I suggested randomly out of the blue.

Of course feel free to go down the road you choose, I was merely providing yet another option.

My iphone 11 Pro Max has terrible signal strengths at my home and other places where previous phones have been fine. 1 or 2 bars max with poor call quality. Tried everything I could find for fixes, nothing worked, until I changed the network setting to 3G. Signal strength now 4 bars. Seems crazy to have top end phone to use 3G but at least I can take calls now.

I just received my replacement 11 Pro Max. It works much better - now at 2 to 3 signal strength mostly but still dips to 1. Still at least it's usable.

Switching to 3G adds one bar of signal strength. To do that... Settings/Cellular/Cellular Data Options/Voice & Data/ (from here you can select LTE or 3G).

It’s defective! Return it!
