iPhone 11 Pro Max 4G LTE Signal Issue

I purchased my iPhone 11 Pro Max a week ago, 256 gb, Space Gray. Had the issue all the time. First we tried replacing the SIM card, but that didn't work. I was on iOS 13.1 , 13.1.1 , and 13.1.2 but none of the updates worked. Tried LTE both with Voice and No Voice, neither stable and probably wouldn't even send iMessage or SMS about 90%+ of the time. 3G would work but did not meet my data needs and the call quality was awful. Within the exchange period of my carrier (Xfinity Mobile on Verizon towers), and got an even exchange of both the phone and the SIM card. New phone working properly now. This doesn't appear to be too wide of an issue, but somehow, there's a bad run.

Here’s my story: I purchased an iPhone 11 Pro Max 256 GB Midnight Green on 9/20/19. My carrier WAS Verizon. I had horrible reception from the beginning. The reception was the worst in my home. Mind you, I live 20 mins away from Manhattan, NY. Shouldn’t I have great service? Especially with Verizon? Fast forward, I spent the better of a week and a half calling Verizon tech support. They reset my number on their end. I wiped my phone three times; only once restoring it from a backup. It was until this passed Wednesday that I had enough. I called Verizon customer support to have my phone exchanged; I forgot to mention, I also took it to Apple to have it check out before the exchange order. The rep submitted my exchange and placed the order for me. Twenty minutes later, I receive an email from Verizon fraud and was asked to call. I called them. Everything went down hill from there. They wanted a photo ID, in which, I had no problem sending a copy. However, they wanted one more additional document, and that is where they went **** crazy! They were requiring either a car registration on my name, a utility bill, or voter ID card. I’m sorry but I don’t have none of those things under my name and I don’t have a voter ID card (I’m a registered voter nonetheless). I offered to send them a paystub, bank account statement, U4 (I’m in Finance), or my student loan statement. They were not willing to take any of those documents I offered. All in all, F U, Verizon! I left that sorry company. I am now on AT&T with a brand new iPhone 11 Pro Max 256 GB in Midnight Green and I am LOVING every moment with this phone. It is now, PERFECT! F U, Verizon! I dodged a bullet! Thank You, AT&T!

Having same issues with my 11 pro max with lte data cutting in and out I have Verizon and already me and my wife having same issues we have swap out simcards and even exchange phones out we used to have Samsung s9 with no issues

That's pretty disgusting. They definitely give you the run around. They tried to say I had the phone past the 14 days and I didn't...I had it since the 20th. Finally returned it today and canceled the line. I have a Note on Verizon but once I get that paid off, I'm saying sayonara. I'm back with Tmobile. It's awesome over here.

Yes, they did! Luckily, they proved themselves to be garbage with the 14 days, so I would say luck was on my side. Now, I’m with AT&T, and I am extremely content with the phone and their service. And, I am also paying less on my monthly bill. Win/Win!

I phone 11 pro max Verizon issues lte cell drops all time called Verizon they on back order til 16th so how can I ask for replacement if they don’t got any apple .. please fix this issue apple it sucks

I have had my iPhone 11 Pro Max 256G for about 3 days from T-mobile. Same problem plus data connection drops intermittently even when I show 2 bars. Have to turn off data(usually go to airplane mode) for at least 20 seconds then turn data back on to get reconnected. Data drops out mulitple times a day even when showing 2 bars. When I recycle data, it searches then shows 4 bars, then shows 1 bar then shows 2 bars. This is true at home in Western NC as well as in Atlanta. I had an iphone 7plus before and never had these issues. Will call tech support in the next few days. This is ridiculous.

I too have had an iPhone 11 Pro Max, 256 gb, Space Gray for about 3 days. Have had this issue for the whole time. On T-mobile. Am on the phone with T-mobile now and they are trying to conference in Apple since I bought the phone through T-mobile.

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.

I returned my Pro Max and got the Iphone 11. Just like last year, I had the XS Max and same thing with Verizon. I went to Tmobile and got the XR. Verizon has had issues despite the phone issue, but when you add the two, it's horrible. It seems that these Max phones have issues with their LTE reception, and until they get it right, I'm steering clear of them. It's a crapshoot because many have issues and then 1 our of 1000 do not. I'm not taking that gamble. I already buy lottery tickets. I'm happy with the 11 for now. Hope you figure out what's best for you. Apple keeps things hush at times!

The POS phone is dropping LTE connection so often now I am experiencing repeated dropped calls. I am now relying on my Series 4 Apple Watch with LTE in standalone mode to make and receive calls reliably.

Yes. After an hour on the phone with T-mobile and even them conferencing in Apple(no help - “you can send it in for repair or replacement”) T-mobile is going to swap it out with a new one (hopefully from a different lot that is not defective) but there won’t be any more in stock until the end of the month or early November. The difficulty arises in that the T-mobile buyers remorse window is only 14 days and replacements won’t be available until well after 14 days. T-mobile is making it work. Unfortunately I sent in my old iPhone 7 Plus for the upgrade credit right after I received this new phone. So there is still potential for this to get screwed up. Crossing my fingers. If the replacement phone does not work I am done with Apple smart phones. Will have to sell my Series 4 Apple Watch too which I really like.

I am in the same boat here. Last week I spent about 45 minutes with Apple support and we kicked off an advanced support session with them pulling logs. I continue to see this issue pop up randomly throughout the day and have to hard restart the phone.

I am running the latest iOS version, latest carrier update patch, and drop cellular service randomly throughout the day.

To me, this seems to be a software challenge and not a hardware issue.

Worst part is I have not heard back from anyone at Apple on the logs with what seems to be the root cause.

Next thing I am going to try is a full phone restore and set it up as new. I am curious if restoring it as a new iPhone vs. from my iCloud backup of my iPhone X could solve this issue.

Will be curious to see if that works. But others on this thread have gotten replacement phones and the problems all go away. I personally think it is a Intel modem issue. I can set my phone in a stationary position watch the signal strength sit at 3 bars for a while, drop 1 bar, lose network connectivity, go to no bars. Turning off cellular data and turning it back on does nothing. Sometime it pops backup by itself and sometime forcing a phone restart is the only thing that gets it to reconnect until the next random dropout. Same symptoms whether in the mountains of NC or in the middle of Atlanta. Phone reboots by itself while I’m my pocket and I know this because when I pull the phone out face recognition does not work and it prompts me for my pin. Of course, the random rebooting pushes one towards a software issue. When I migrated from iPhone 7 Plus I used the phone to phone method, not restoration from I cloud. While configuration specifics came from the old phone, all the apps seemed to be downloaded fresh from the apps store as I could slowly watch them populate.

Well sounds like we might be having two different issues here. My phone is having more of a cellular drop issue and a hard restart seems to work. From what I read through folks who replaced the phone still had this issue which is what leads me to believe more of a software glitch in the phone.

I guess before I restore the software to scratch doesn't hurt to get it replaced. I do have AppleCare+ on the device and with the amount of support tickets I have rocking shouldn't be an issue.
