People have tried that. It either works for a short period of time or not at all. But working for a short period of time makes it certainly look like it's software related.I’ve fixed my LTE issues and wrote a post explaining how here: https://forums.macrumors.com/threads/fix-vzw-connectivity-charging-issues.2145835/
If the iPhone Xs is at the same dbm level as other phones it downloads as fast as the the other phones. The problem is, at least with mine, the iPhone Xs signal was consitently lower than my other phones. It couldn't get as good as a signal and it fluctuated wildly. It would go from -95 dbm standing in my open front door all the way down to -115 dbm without even moving. It never grabbed a signal and stayed with it. In field test it was constantly going up and down.Huh? If the antenna is designed poorly, it wouldn't be able to download at similar speeds over different signal strengths.
The guy with the FCC report said he thought the effect would be an inability to hold on to signals in weak conditions, but the PCMag tests show it holding on fine until -128db.

I'm starting to think I was lucky enough to receive one from a bad "batch". My screen was also really yellow compared to my other phones.In field test mode, my XSMax was showing a constant, stronger signal than my wife's 7plus. And there was at least one location in town where I used to have no service with my own 7plus, but had a signal with the XSMax. Which is why I really don't think a bad antenna design is the problem here.

What network are you? Mine is T-Mobile and no band 71 yet.
Tmobile here too, no yellow screenI'm starting to think I was lucky enough to receive one from a bad "batch". My screen was also really yellow compared to my other phones.

Re: yellow screen. Maybe a stupid question, but did you make sure to turn off True Tone?
A bad batch would not have anything to do with that! It might be just one faulty component manufactured by one of the suppliers. Why would they need an FCC certification report?! Apple has had it many times before. We’re not talking about a complete redesign here.If it were a batch issue, we would know. Any change to the radio components requires a new FCC certification report.
In the unlikely event Apple acknowledges a hardware issue, it will still take a long time for a redesign.
same carrier? Which one?So I got to test my XS Max against my father's Qualcomm iPhone X.
Surprisingly the XS Max was getting 2 bars LTE when the QC iPhone X would only get 4G. Speeds were also markedly better on the XS Max.
I actually think Apple has done a better job this year than they did before. The new intel modems are MUCH better than the old iPhones. Even the Qualcomm versions seem to perform wore. This is all relative to wifi and internet. I have not tested phone call reception on both phones.
That’s interesting. Connected to same server?Did a test today where I literally stood next to my friend who also has a XS Max 256GB (even same color) on AT&T (same carrier) and did several speed tests (we had the exact same number of bars...and did it without cases to control for signal variability). He got 25mbps download every time and I got 3mbps every time. I also max out at 3mpbs download for LTE every single time I run a speed test no matter the location or level of signal.
Yes...I just posted screenshots above.That’s interesting. Connected to same server?
Different plans? Post vs prepaid?Yes...I just posted screenshots above.

But not necessarily the same band.Yes...I just posted screenshots above.
How do I test/see that?But not necessarily the same band.
You need to go into field test mode on both phones. I don't remember where it shows what band you are using.How do I test/see that?
Is there a guide to do it on iOS 12?You need to go into field test mode on both phones. I don't remember where it shows what band you are using.

Yes. http://osxdaily.com/2018/05/02/use-field-test-mode-iphone-x-ios/
Also make sure you reboot phone after done using it, or it will keep running in the background.
Also, you can check what bands are available in your area, by selecting location and carrier.

In my city, all the towers on verizon are using bands 4 and 13, with only one of their towers using bands 2,4 and 13. Those are all the older LTE bands, and probably why I haven't seen much of an issue in my city.
