[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
Curious to see some comments from anyone with Mi Max 3 on T-Mobile or AT&T - are you able to get a stable LTE connection? Overlapping bands are only B4 and B5, so it may not work well everywhere in US. Some speed test results and general comments on LTE connection would be appreciated.
[Xiaomi Mi Max 3 Questions & Answers] omniphil:
I am still awaiting my unit to show up, its been "in transit" for 2 weeks now. I have AT&T and am also curious about this.

I have used many overseas phones in the past and even without LTE I never really had any issues with speed. HSPA+ always seemed to get the job done fine.

LTE in USA

There's another thread on the board where a fellow in NJ is using the Mi Max 3 on T-Mobile and keeping Band 4 LTE almost all the time. I'm on T-Mobile as well and I'm seriously considering the device.

I am curious, though, if the Global version will have support for additional bands?
[Xiaomi Mi Max 3 Questions & Answers] spire-hunter:
I got this phone last week and am on Tmobile. I'm getting 50mbps down with no drops yet. I love it. The only problem I had at first was with calling, but after enabling voLTE by typing *#*#86583#*#* into the dialer, problem solved.
[Xiaomi Mi Max 3 Questions & Answers] misterk267:

On T-Moblie

I am in TX using T-Mobile and the connectivity was horrible regardless. Even had T-Mobile store try to help.

Anyway, I followed the Xiaomi advice to revert to the China ROM (the "Global" Versions are BS and have this connectivity issue from some suppliers).

I need to flash the ROM tonight since I wiped EVERYTHING after fighting with it all night.

Apparently wiping "System" in a Xiaomi might be a very bad thing. I'll find out. I used TWRP BTW.

what is "super fast"? what bands are you connecting to and what speeds? Is the connection stable, or are there drop-offs?
[Xiaomi Mi Max 3 Questions & Answers] cmarkortiz:
No drop offs and lte speed is fast loads everything instantly. (Not advanced techie so I don't run speed test and antu and all that stuff) just speaking in regular terms. I'm assuming I'm connected to band 4 for TMobile as phone shows lte in status bar.
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
Antutu benchmarks have nothing to do with internet connection quality or speed. Do you feel you need to be an advanced techie to type speedtest.net URL in your browser or install any of the Play Store speed test apps? I'm really not sure what "regular terms" mean in this context.... You also said because you see LTE icon in status bar of your phone you assume it is connected to B4. T-Mobile USA supports FDD-LTE bands B2,B4,B5,B12 and B17 (FCC roaming support requirement), so B4 and B5 are both overlapping bands with what Mi Max 3 supports. Being connected to either would show LTE icon in the status bar of your phone - why do you assume it's specifically B4?

Not responding anymore to a negative comment, have a great day
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
It is absolutely your right to not contribute and to not respond to any questions, but I take issue with you calling my comment "negative". You said some things I did not understand, we were having a discussion,so I was merely asking for clarification how you arrived to your conclusions. If somebody shows a screenshot, or says they installed a networking app, like LTE Discovery, which shows their phone is connected to B4 - that's a helpful comment. However, when you say you "assume" you are connected to B4, when there are several compatible bands available - it's a legitimate question to ask what that assumption is based on.
[Xiaomi Mi Max 3 Questions & Answers] Ald47:
Absolutely horrible!!! Now that I've got the Chinese ROM installed, the signal is perfect!

With the fake ROM I could connect 1/40 times.

Now it's every time.

Also, did you notice random contacts didn't come over with the Google sync???
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
Got my Mi Max 3 today, 6GB/128GB version. First impressions - very solid device. Stock Chinese rom. LTE connection to B4 is very stable on T-Mobile USA. Getting 10-15mbps down in work area, which is the same as with T-Mo branded devices, no drop-offs. I'll admit the only partial LTE compatibility was a concern, but the connection seems to be rock solid and T-Mobile has good B4 presence everywhere in my city. Getting Google apps to work on it was a bit of a pain, but once you do it once - you dont have to do it again, and you know how to anyway.

Immediately requested bootloader unlock through Mi Unlock tool, because of rumored delays in mi account unlock authorization - the tool told me to wait 720 hours, which is 30 days.... It's probably not gonna be anywhere near that long , but still very annoying because once you unlock bootloader - your device does factory reset and you lose everything you've installed/set up. Can't invest time into configuring your phone until going through that forced factory reset.

Considering on suggesting this to a relative who would upgrade from the Sony Z Ultra that had 6.4 inch screen.
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
I bought it from eBay. The seller I got it from is currently stocked out, but there are many more. Just search eBay. Dont know what your relatives preferences are, but people usually care about a lot more than screen size.

[Xiaomi Mi Max 3 Questions & Answers] adibeckett:
Hmm, both of those phone don't have Band 4.

Are any of you worried about the lack of Band 12 or other TMobile LTE bands? I think I read somewhere that in the future they may phase out Band 4 so everyone can be on Band 12. Hopefully that won't be for a long while.
[Xiaomi Mi Max 3 Questions & Answers] nijel8:
You should be worry if the main US LTE bands 12 and 17 are missing and LTE is important for you.

But IMO you shouldn't... Using first Max for over 2 years on ATT network HSPA only all over US I haven't missed LTE speeds once. HSPA is fast enough for almost anything these days...
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
Disagree with everything you said. First of all, B12 and B17 are NOT main bands on any network. In fact, in most areas, including mine, the signal on B12 is rather weak, so whenever my other device connects to B12 against my will - I get very slow speeds and try to reconnect to another band. So I see lack of support of B12 is an advantage.

Second, I've used devices, such as Huawei MediaPad X2, which were HSPA+ only in US and HSPA+ is most certainly NOT enough for half the stuff people do. No proper multimedia watching in high resolutions, no TV streaming, no remote desktop, no network gaming etc. works with HSPA+. That 5-6Mbps down and 1Mbps or so up you get in most places is insufficient in today's digital world. T-Mobile is also slowly retiring its HSPA+ infrastructure, so soon HSPA+ won't even exist. You need LTE, period.
[Xiaomi Mi Max 3 Questions & Answers] Ald47:
You're right about the bands. I'm on band 4 almost exclusively in Houston. Not sure what band I'm using on calls, but I do see it switching to 3G.
[Xiaomi Mi Max 3 Questions & Answers] nijel8:
I guess everybody on the net is wrong then... Wikipedia, forums, specialized sites etc listing 12 and 17(if 12 not present on device) as ATT main LTE bands and 12 as T-Mobile main band. The fact you stated about slow 12 band speed on T-Mobile just confirms it's the main band -> crowdy -> slow. 4 wasn't even there couple of years ago, many old devices on thair network doesn't even support band 4 hence less monkeys on the tree, better speeds.

Disagreing with the rest of it is completely normal... It's an opinion, not a fact...

Houston, TX

First off, Lots of guys from Houston here. I am also in Houston, TX (Katy to be more precise). I got mine around August 21st, 6GB/128GB Black version. It arrived with the fake ROM and I immediately flashed the Xiaomi.eu ROM. But I am currently running MIUI Pro 8.9.6 and it's excellent. I cannot speak the same for the LTE speeds because I am using Ultra Mobile (Don't judge Me :D ) .

As they have 3rd or 4th access to T-Mobile towers, I get quite very slow LTE speeds. But when you are paying $17/month for 4GB data, unlimited talk text, unlimited international to 80+ countries, $10 International Roaming credit, and $2.50 to call every other international country, one cannot complain about LTE speeds.

But overall, I am quite pleased with the phone. I too would love to see pics of the Blue Mi Max 3. Cheers Guys.

[Xiaomi Mi Max 3 Questions & Answers] Damionix:
You Don't Have To

I don't think you need to switch unless you really want to. I have always preferred the Chinese ROMS as they are always more feature rich. But I prefer the forks of them like Xiaomi.eu, and in my case MIUI Pro.

I prefer MIUI Pro since it is so so so feature rich, and the battery and performance is always stellar.
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
I'm a network and software engineer, among other things...What I told you about B12 and B17 not being main bands is NOT an opinion - it's a fact, and it comes from fairly detailed knowledge of GSM networks setup in US. Both, AT&T & T-Mobile have B2 as the main LTE band. The segment of 700Mhz (B12) T-Mobile owns is not even suitable to be a main band, for technical reasons I won't go into. All I'll say is 700Mhz spectrum doesn't even properly support carrier aggregation or MIMO.

"everybody on the net" is a figment of your imagination - I've never seen anyone claim that B12 and B17 are main LTE bands for US carriers. Most people dont even understand what main band is, so they don't comment, and those who do would never say B12 and B17 are main bands - that's very wrong. The fact, that you used deeply flawed logic of how saturated a band is to "determine" it's the main band shows how little you know about networking, US carrier infrastructure and LTE technology.

If you want to rely on and cite "sources" like phonearena, and some random user (not at&t tech, not forum admin) on at&t forums, who says "My current understanding of the LTE bands is as follows", and who probably knows even less than you - go right ahead. If you on the other hand, are interested in the actual, real information about how US GSM carriers have built out their networks, what bands they use for what and why - you can PM me and I will spare a few minutes for you. I'm not, however debating this anymore in the public thread, because this is off topic and has gone long enough. I created the thread to discuss MI Max 3 in US, and we're going to keep it that way.

I'm up in New England on AT&T, currently running Xiaomi.EU (8.9.13). Cell signal has certainly been challenging and it seems to have issues switching towers when driving around at times. If I go into an area with no signal sometimes it is hard for it to pick it back up. Putting it in Airplane mode temporarily seems to fix it. But cell signal in general on this phone in the US just isn't 100% reliable in my area.

Some Notes....

Android Auto only appears to work on the Xiaomi.EU roms. (Chinese roms seemed more stable, but I need Android Auto functionality)

Any of the "Global" roms left me with no working cell signal at all at my house. I would avoid those all together.

I don't seem to be able get any video calling apps to work correctly, the person on the other end says the Mic cuts in and out)

Audio calls appear to work just fine.

I had to switch back to my Mi Mix (The Mi Mix is working flawlessly on AT&T) for the time being as the video calling is something I use daily unfortunately. I am really hoping that some future rom releases get things more ironed out, but I am really concerned about the radio firmware and the reliability of the network connections. These phones are clearly not designed for the US market and we know this going in and we take a risk, unfortunately this time around it looks like I lost. At least for now...

[Xiaomi Mi Max 3 Questions & Answers] opasha:

[Xiaomi Mi Max 3 Questions & Answers] omer919:
Let me ask this first, have you installed xiaomi.eu 8.8.30 in the past? If so you have ARB

I suggest clean installing the rom from 8.9.13 china beta FASTBOOT. I am on clean 8.9.13 and I have LTE+ all the time and no signal issues at all.

if you have ARB: you cant just fastboot to 8.9.13 again. so flash 9.6.12.0 first and then 8.9.13 and after that xiaomi.eu 8.9.13

if you dont have ARB: clean install 8.8.9 from fastboot and then install xiaomi.eu 8.8.9 (NO ARB)
[Xiaomi Mi Max 3 Questions & Answers] omniphil:
I have not installed 8.8.30. I started with 8.8.9 China, which then i upgraded to 8.9.6 China, Which i believe tells me I have ARB.

[Xiaomi Mi Max 3 Questions & Answers] omer919:
ARB is on your hardware

when you installed china 8.9.6 you got ARB

wipe every partition on your twrp, clean flash 9.6.12.0 from fastboot, wipe every partition on your twrp, clean flash 8.9.13 from fastboot, and then install xiaomi.eu 8.9.13 using my guide on the forums, dont forget to format userdata in twrp, change data partition to f2fs after flashign xiaomi.eu (before first boot, after installaion)

sent back

sent the 6gb 128 mi max3 back, I could not get the VOLTE to work, on T-Mobile, was the main reason,

but

compared to my 2 year old zte zmax pro, I have 2 [MENTION=8006379]Z981[/MENTION] and one @z982 from cricket

so the actual phone is about the size of my zte with the case on but substantially thinner, that was good. screen was amazing.

but

the speed of opening and closing stuff was adequate but when I realized it had a 63osomething vs the galaxy havein an 8something I felt like wtf did I just spend 400 on I would have paid more for a better processor and compared it to my zte it was only slightly faster and slower by far compared to the s9 Galaxy, I was upset it was already slow.

a few bugs here and there,, like no moviepass app support

phone when you have 2 sims keep asking what sim to use when I set it many times in preferences and changed the setting looking for soultions

air launcher kept having issues and odd stuff would happen with my home screen like the Wi-Fi button not working then getting 4 alerts about Wi-Fitrying to be turned on by air launcher.

kept getting alerts about data usage, and reset various data settings about 10 times trying to make it go away,

tried to turn on volte by type in the code 3 times and nothing happens, so I went into the phone drill downs to look if it was active , no. and not changeable with any of the buttons ,

its hard to go from my zte with zero problems that's just slow, to a slightly faster phone that looks amazing but has a bunch of small issues and wont let me surf when im on a call, or run down new map directions when im talking. im not spending $1000 on a galaxy so what do you think is the next option for a bigger than 6.5" Phablet with good bezel ratio?
[Xiaomi Mi Max 3 Questions & Answers] Apo11on:
Too many random, abrupt thoughts for 1 post. Hard to see any actual issues reported. Some of the things you call "bugs", like "no moviepass app support" have nothing to do with Max 3 - an app has to support the device, not the other way around. I have next to zero issues on my Max 3 in US, so all your "small issues" must be specific to your own setup, what you install and how you configure the phone.
