OK, so far we have some info on the D820 (via the FCC) and D821 (via the leaked service manual).
D820: LTE bands 2/4/5/17/25/26/41
D821: LTE B1, B3, B5, B7, B8, B20
D821 looks like a good match for European, African and most Asian LTE bands, and D820 looks like a match for American & South American LTE bands. China does not appear to be well covered by either model, so there may be a third model if the Nexus 5 is released there.
--------------------------------------
UK:
D820: No carriers
D821: EE (3, 7, 20) 3, (3, 20), O2 (20), Vodafone (7, 20)
US:
D820: Sprint (25, 26, 41), AT&T (2, 4, 5, 17), T-Mobile (4)
D821: No carriers
Philippines
D820: Smart Communication (5)
D821: Smart Communication (1, 3, 5)
--------------------------------------
Please post below with which model is supported by which carriers in your country, and I'll add it to the post.
--------------------------------------
Two models, two spec revisions (with inexplicably lost bands), or the same model with bands 'locked off' for different region (is there a regulatory precedent for this, e.g. WiFi channel 14)? My guess is that the hardware is the same and the bands are locked off somewhere in the firmware, but maybe someone familiar with the chipsets can chime in as to their capabilities?

Its possible that the bands are modem locked. ie with n4 lte band 4. We really won't be able to tell until we get our hands on one.
So officially now, no Verizon love at all.
Sprint supported. Hell yeah.

Where is the official proof no Verizon support?
Sprint uses bands 25, 26, and 41 for U.S. version.
AT&T uses bands 4, and 17 on Nexus 5.
T-Mobile has just band 4 from the looks of it.

Sorry, I shouldn't say official. It hasn't been announced but the bands listed above do not include Verizon's LTE network. Apparently it supports band 4 wich Verizon is supposed to roll out in the future but everyone else is supported in the US. Even US Cellular just no Verizon from the looks of it.
Ugh thanks. F Verizon. Haha

So there is still a glimmer of hope haha, but knowing Verizon (angry Gnex owner here) and not carrying the Nexus 4, I would not be surprised if they don't support the N5.

I don't know why they just don't do like the Nexus 7 2013 and just put the Verizon bands in there. Verizon won't be happy but with N7 owners, they were able to activate a SIM in another device, then put it in the N7 for service. They just couldn't activate the SIM in the N7.
Verizon is a pain. My GNex is feeling the pain of Verizon but still overall a great device with tons of dev support.
I do remember there being some issues with the GNex release about signal strength and had a technical support nightmare. Plus the problem of Google releasing CDMA source code in AOSP. Not sure how Sprint does it.
Even if Verizon LTE isn't supported now, would it still work for voice service (3G speeds)?
There is mention of the Radio having an adjustable tuner. Perhaps it can tune in to Verizon LTE unofficially.
Verizon uses LTE 13 currently but plans on expanding to 4.
Having Verizon LTE support is still moot if the CDMA voice fall back isn't there. This after all a phone and Verizon doesn't have vo/lte. This makes the the situation with the new N7 different.

In my opinion D820 will also have "Band 3" support.
It's the most used band in the world. And it will be very stupid to sell a Nexus 7 2013 US edition with Band 3 support...and a Nexus 5 without it.
Since, the Nexus is a phone it's more required when travelling than an LTE tablet.
Also, people told me that the FFC doesn't need to approve that Band so we still have no info about this.

I've just dug in Google for a few minutes, and I can't find any info supporting this...the FCC seeks approval on all bands under its perview, to ensure there's no disruption to other frequencies. The fact its a 'world' band is immaterial for release in the US..it would still receive testing/verification.
I am a bit disappointed by the two models, would have preferred a single model that supports all the bands listed (don't know if that is technically possible yet). I travel a lot to the UK and it would have been nice to have LTE while there.

The contest wasn't that the D821 would not support band 3 (as you say, the manual clearly states it), but that the D820 would (the FCC filing made no mention of band 3 being among the supported LTE bands).
The FCC website is inaccessible for the moment due to American governmental sillyness, so it's not possible to see if the D820's details have been updated.

Usually, Verizon phones require CDMA for Voice and Text. I'm not sure if this phone supports Voice/Text over LTE or even if Verizon's LTE supports that yet. But if LTE Voice/Text is not supported then the device would be Data-Only, no calls or texts

VoLTE is supposed to be coming soon, I don't know if that includes texts. It should work with the Verizon messaging app, as it sends text over WiFi on devices that have it.
I really hope someone can get it working 100% on Verizon, I've got a Moto X and I don't want to upgrade my phone to something >5" but still want a really good specced phone when I do upgrade.

I should clarify that by messaging I meant SMS. which will use CDMA. I glanced at the white paper for this phone and so no mention of CDMA so I'm willing to bet this phone will only work for AT&T and T-Mobile in the U.S. There is hope for a Z3w Compact since there is going to be a Z3 verizon compatible version. but we'll have to wait and see
And the original Moto-X is still a damn good phone, I wouldn't swap it out yet for probably another 6 months to a year at least

Yeah, I knew you meant SMS. There is an SMS app from Verizon called Messaging (I believe) that allows you to send SMS over data connections (well, its meant for WiFi but it should work over LTE.) With VoLTE coming soon, it might just work all over LTE but I'm not sure. It would be a bit annoying to have to use Verizon's messaging app but if it works that would be a nice upgrade path if I decide to upgrade soon. I'm also looking at the Galaxy Alpha. If I don't though, I would be more than okay sticking with the Moto X for a few more years.
As a follow up to my original post, I heard there may be a version available for Verizon in the US. Does anyone know if this is accurate? Thx

MetroPCS's original network was CDMA, but since the T-Mobile purchase if it uses a SIM it should work because that should use T-Mobile's towers but I can't say with 100% confidence, I'm a T-Mobile user
Question is - VoLTE isn't something that can be 'hacked', correct? If it were enabled on the Z3v, for example - it wouldn't just be a matter of extracting some files from there and voila, right?
Verizon VoLTE is not going to help. For now, it only applies when both parties to a conversation have it and are both on 4G. That's no substitute for CDMA calling.

Thanks for clarifying that it's a technology that requires the participation of both parties (though I guess that wouldn't be true of landline phones). Any mobile VoIP out there that doesn't suck these days?
They don't use it for land line calls. As it's currently implemented it only comes into play when two cell phones can both use it.
VZW employees I spoke with said they've been told not to oversell it because the benefits aren't really experienced that often.
I've activated on Verizon
My Z3c has successfully connected to Verizon's LTE network, once the other radios are disabled in the phone info screen (IOW the phone is in 'LTE Only' mode).
However, while it connects to Band 4 without issue, it doesn't see Band 13 at all, even though my other phone, a 2013 Moto X, sees it just fine. Is there any reason to think that Band 13 is disabled in the phone by default? Or is Band 13 varied enough that the phone only supports some specific part of it? Or is the Band 13 support just a typo in the specs? Note, this is the D5803 model, bought directly from the Sony Store here, not the D5833 model which lacks a bunch of radios.
---------- Post added at 03:42 PM ---------- Previous post was at 02:58 PM ----------
Never mind. After power cycling the cell radio, using the LTE Discovery app, I did, in fact, manage to connect to Band 13 as well. The signal on both is reported as being much weaker than on my Moto X, interestingly enough. Moreover, it switches to Band 4 after a few seconds, I suspect because Band 4 is a lot faster.

Hey, I'm looking to make the same move and wondering
1) How many months/days have you been using your Z3c on Verizon?
2) Did you activate on a new line or replace phone on active line? Any look-for's?
3) Are you using Hangouts for Google Voice? Any drawbacks compared with previous calling/texting experience?
*4) Are you able to add the Advanced Calling 1.0 feature for VoLTE?
Thanks!
I bought a Xiaomi Mi Note LTE (Dual Sim) from China recently but cannot use LTE 4G in the UK.

It turned out that Mi Note LTE (Dual Sim) support LTE B3 and B7 (The international version supports B1 and B3)
But my carrier Vodafone UK rolled out LTE throughout the courtry with band 20 (800Mhz) but LTE Band 7 is only available for 3 cities at the moment. ( Only EE and Three support B3/B7, which is the reason I cannot see 'Vodafone 4G' and 'O2 4G' but 'EE 4G' and 'Three 4G' in the network list. source, source, source)
So I tried the guides: here, here, here and here to unlock B20 on my phone. (Many thank to @BlackSoulxxx, @fffft, @olokos, @devilsshadow and @Albirew)
I went through all the steps and set the value into 6828 (and even 6829) permanently but still cannot see 'Vodafone UK 4G' or 'O2 UK 4G' on the network list.
I googled a lot but still couldn't find the solution.
I found others who have Xiaomi Mi Note or Redmi have the same problem and want to unlock different LTE bands. But some of them stuck in the middle of the steps especially the prerequisites and couldn't go through. Maybe unlocking other LTE bands is working for them. So I decided to write the step by step guide and hopefully throw out a brick to attract a jade.
The lawyers made us do it.
We have to post an obligatory warning.
We don't think that this mod will cause you any problems. But we can't guarantee that. I never tried it on devices other than Mi Note LTE (dual sim).
You assume all risks if you proceed, including the risk that your phone might object, meltdown, brick or void your warranty.
Let's start
1. Root your device.
2. enable diag mode by entering *#*#717717#*#* on the dialer and download the driver from here (thank @m11kkaa).
Once diag mode enabled, you can see the Device Manager from PC like this:
then right click the first 'MI NOTE LTE' and install the driver you just downloaded
you will see this if successful
3. Download and install QPST
4. Download and install QXDM
5. Open the "QPST Configuration" program, you should see below straightaway:
You couldn't see this until you finished step 2 successfully
6. Now select the QPST Start Clients > Software download > Backup > Start. Wait until the status says 'memory backup completed'. This saves a backup copy of your phone's stock NV memory to your computer in case you need it later.
7. Leave QPST open and navigate to the C:\Program Files (x86)\Qualcomm\QXDM\Bin folder. And right click on QXDM.exe > run as administrator.
8. Go to options -> communications
Target port -> select COM6, then OK
9. select Nv Browser from view
10. select LTE from Category Filter, then you can see 06828 and 06829
11. click on line 06828 (lte_bc_config); click the Read button, save somewhere the original value in case something goes wrong (inside notepad or anything), the original value on my device is 2061584302148
12. Let's talk more about the value, source
in my case, the value for 06828 is 2061584302148, using Calculator (programmer mode) to change it to binary value is
11110000000000000000000000000000001000100
from right to left, the 3rd, 7th, 38, 39, 40,41 bit are 1, which means band 3/7/38/39/40/41 are enabled
I want to enable band 20 so change the 20th bit to 1
11110000000000000000010000000000001000100
the corresponding Dec value is 2061584826436
13. click on line 06828 (lte_bc_config); click the Read button, replace Input value with 2061584826436 (please don't be an idiot and don't edit the empty one with "ext" in the name) and click on Write button
OK THAT IS IT. Restarted Mi Note, and then see if the value set permanently.
BUT LTE BAND 20 IS STILL NOT UNLOCKED.
I changed the value to 2061584826368 which is
11110000000000000000010000000000000000000
Disable B3 and B7 to see if the value is working, It worked, I cannot see EE 4G and Three 4G any more.
let me know if anyone unlocks other bands
ps: don't forget to disable diag mode by entering *#*#717717#*#* on the dialer.
DID I MISS ANYTHING?!
and thanks in advance for any idea.
Thanks @BlackSoulxxx, @fffft, @olokos, @devilsshadow,
@Albirew and @m11kkaa anyway even if I couldn't unlock Mi Note, I had a lot fun playing it.

Hello,
I need to unlock just one band on my Redmi Note, band 20. I don't have a Mi Note, I have the cheaper more affordable option the Redmi Note 4G.
However, I know this trick will work on it, it's a similar Snapdragon chipset, I just haven't tried it yet, as I'd love some advice before diving in.
Currently, my phone has:
FDD-LTE (1800/2100MHz) & TDD-LTE (2600MHz)
So basically, that's band
2100Mhz - Band 1
1800Mhz - Band 3
2600Mhz - Band 7
I'm on Three UK, which only has 2 bands on it's current spectrum,
Band 3 and Band 20, which of course is 800 and is NOT unlocked by this phone.
Is it possible to unlock Band 20, without losing other bands. I only need Band 3, and Band 20, and I'll have full 4G support.
10000000000000000000000000000000000000101
Yikes, this is my binary. Which is more confusing than ever. I get that it's little endian, so that means left to right, 101 that's 1 and 3. I'm confused though why Band 7 hasn't got a bit and what the very last bit refers to in my case.
---------- Post added at 01:41 PM ---------- Previous post was at 01:33 PM ----------
OK. I think I've found my mistake. Apparently, it supports Band 3 and Band 40. So maybe not Band 7 after all. This would make sense.
Band 1
Band 3
Band 40
I'll work it out for sure now

Balls
10000000000000000000000000000000000000101
There's 41 characters there. That's now messed up my head because surely that means it supports Band 1 and 3 and 41, not 40. I'll continue to work on this.
---------- Post added at 02:00 PM ---------- Previous post was at 01:50 PM ----------
Nope. I was right. I downloaded LTE Band Calculator off the Play Store, and 1 3 and 41 = 1099511627781, the number in my NV RAM.
What the hell is going on!!? I've read this phone supports 1, 3, 7, then it was 1, 3, 38, then 1, 3, 40... Now my NVRAM tells me it's 1, 3, 41.
Christ almighty. Apparently, band 41 is accessible from devices with Band 38 unlocked, but that doesn't make sense because India is running on Band 40.
Seriously, getting, pissed, off.
OK. An update.
I set my value to 10000000000000000000010000000000000000101 which is 1099512152069. This is Band 1, 3 20, and.... 41, which was apparently unlocked before. Not convinced though.
So far, can't tell whether it's actually done anything. EE 4G is still there, which makes sense because they have strong 4G in the UK. O2 which has piss poor 4G in the UK, only use Band 20, so seeing that as an option in the Network selection list would be a perfect way to check how valid this experiment is. I'm currently in Wilmslow in which O2 suggests I should have strong coverage, but nothing showing up yet, only EE.
However, I'm in a building, and it's a big building, and signal varies. Really, the best time to know is outside. Perhaps I will get O2 showing up with 4G in the network selection as an option.
The saga continues

Hah, another update. OpenSignal map, which uses data collected from actual devices shows that O2's 4G data is piss poor in Wilmslow (despite their claims). I'll wait then, and report back with further results
what is the device code? mine HM Note 1S CU KHKCNBL.
Bad news, looks like you can't unlock band 20 OnePlus One users found this out. Perhaps you can't unlock band 20.

You did a great job on this tutorial with a load of screens.
Have you considered there may be hardware limitation concerning LTE20 ?

My last couple of posts seems to possibly clear this up. It's very possible that Qualcomm haven't enabled Band 20 in the modem.
I wonder though, if we flashed a modem for a different device, whether we could unlock band 20....... food for thought isn't it?
---------- Post added at 04:06 PM ---------- Previous post was at 04:02 PM ----------
From the Zenfone 5 with the same chipset, again no band 20:
GSM: Band 2/3/5/8
WCDMA: Band 1/2/5/8
TD-SCDMA: Band 34/39
FDD-LTE: Band 1/3/7
TD-LTE: Band 38/39/40/41
From the Lenovo 856:
(4G): FDD - LTE: B1 (2100 MHZ) / B3 (1800 MHZ)
However, contradicting all that, from Moto G 4G, which uses the same chipset:
US Model: Bands 2, 4, 5, 17 (1900, 1700, 850, 700 MHz)
European model: Bands 1, 3, 7, 8, 20 (800, 900, 1800, 2100, 2600 MHz)
So from a purely hardware perspective, it looks as though it's very possible to do this. I wonder if flashing a Moto G 4G Modem would unlock Band 20....
---------- Post added at 04:10 PM ---------- Previous post was at 04:06 PM ----------
Some China mobile. Same chipset:
FDD-LTE BAND 1/3/7/20; TDD-LTE BAND 41
Again.... Band 20.
It's possible, we need to flash a Moto G 4G Modem though.... now, talking about it is easy, but how we do it, without killing our devices, that's where it becomes fun, because I doubt we can just flash the baseband and assume it'll work. That's got lost IMEI written all over it.
Thanks for all your hard work AMD details how to. I'm able to add those band to my Redmi NOTE 4g but unfortunately, nothing works. I believed it's the hardware limitation. My Redmi Note 4g only supports FDD-LTE band 1, 3, 41. I needed band 2, 4 to beable to work with my US network.
Luckyly, I'm fortunate to purchase a HK model of Xiaomi Redmi NOTE 4G. this one ssupported FDD-LTE band 1, 2, 3, 4, 7! I can now use my US tmobile LTE network without any problems!
The questions I have now is:
is there any way to extract the modem that I have in the HK model Xiaomoi Redmi NOTE 4G and make a flashable zip file to flash it in my China Model Redmi NOTE 4G using CWM recovery? I would LOVE to help those people who bought the China model of Redmi NOTE 4G that couldn't use the LTE in the States. Anyone knows how to make a flashable zip with my modem in it?

Thanks for all your replies guys.
I remember last time I flashed this kind of thing is when I was still in uni and flashed BIOS on motherboard......over 15 years ago......
Flashing the modern or baseband sounds promising but dangerous as well.

It's the same phone with the same chip and everything. It's not from a different phone with the same chip I'm talking about in my case…
China model of Redmi NOTE 4G is widely available on the net (FDD-LTE band 1, 3, TD-LTE band 41). And it's the ONLY model that people can buy at the moment. So people who bought that were pretty much stuck with HSPA+.
So. If any XDAer out there know how to transfer my HK model (FDD-LTE band 1, 2, 3, 4, 7) modem or baseband to the China model will be much appreciate! It's almost impossible to purchase the HK if u r not living in HK.

I loved the Mi NOTE! I like the design dual glass and OIS camera. I'm hoping to purchase the Mi NOTE PRO when it come out next month. But having incompatibillties LTE band is the only problem keeping me back. I've been with Xiaomi phone since Mi2s. Now I'm using the HK model Redmi NOTE 4G because it's the ONLY Xiaomi phone right now that is 100% working with US LTE networks.
Xiaomi's 1st Global Mi phone code named "i" will be announce on the 23rd this month in India. Rumors said Xiaomi called this model the "Global Mi Phone" was because of the 4G LTE it supported. So if the Mi NOTE PRO has the same band as the regular Mi NOTE, guess my next Xiaomi phone will be the "i"…
Isn't it a case of Global Rom vs China ROM? The Global ROM flashes the global modem although, I've got a global ROM and i had 1, 3 and 41 myself.

nope. flashing the global rom will not change the modem of the phone. my HK model of Redmi NOTE 4G came with HK version of MIUI V5, then updated to Global version of MIUI 6 and now i'm using the Chinese version developer rom. and my 4G works on all 3 roms.
if that's the case, it might be the LTE antenna were different.....but we needs some expert to confirm this.
I'm not even aware there was a Global version and a HK version
Xiaomi Redmi Note 4G LTE band unlock - Tutorial
Thank you very much for this wonderful detailed explaination, @GeorgeZZzz. Unlocking addtitional bands worked like a charm. Sadly as with each of you, there was no success on finding any LTE connection on band 20. I'm curious how bands 2, 4, 7 or 17 will work during my planned summer vacation in the US. Since after reading several of the previous unlock threads I fear it's all antenna related and not so much a snapdragon/software unlock issue. If that's truely the case we won't have any luck.
However during my unlock session in QXDM I had an interesting find:
Only an idea, but maybe the bands are additionally hardcoded into the firmware?
Anyways, it's nice playing around and thanks once again @GeorgeZZzz for making it easier with your "tutorial". :good:
I'm looking at buying this phone - my carrier Koodo (canada) has band 4 for LTE. I understand that this phone doesn't support this bankd for LTE. Anyway to unlock this band?
I've been reading this - http://en.miui.com/thread-311977-1-1.html
has anyone successfully got this to work with Koodo LTE?
Try asking here: http://forum.xda-developers.com/mi-5/how-to/mi5-mi-max-unlocked-bands-successfully-t3420808
Doing just a quick research I found out that Koodo is using Telus and Bell network. Telus is using band 5 for LTE, band that is supported by Xiaomi MI5. Take it with a pinch of salt tho. If you want to ask Koodo directly, my advice is not to ask someone in a showroom. I don't know how it's in Canada, but here in UK these guys have absolutely no idea what they are talking about. Call customer support and ask to be redirected to technical department. There you have big chances to talk with an actual engineer. Good luck.
where in CA? The Telus' side has LTE band 5 (most places), 7 (city centres), and 40 (???) deployed; Bell's side has band 7 ('ronto) and some band 5 deployed.
I guess this thread is in the wrong section - should have been in the q&a section.
Any mods kindly move it to the q&a section ...
In Calgary, CA. Does anyone use Mi5 in this part of canada and get LTE with Koodo?
I just got my Mi5 a few weeks ago - using it on Koodo in the Vancouver area. Enabled LTE and it is working, however the speeds are not much better than HSPA+. My girlfriend gets significantly better speeds on Telus with her iPhone 6. I keep meaning to steal her SIM and test both in my phone at the same time to see if it is the phone or the network, but I haven't yet.
I would post screenshots but apparently I need 10 posts before outside links will work. try putting https:// in front of the below text

Mine is connecting to Band 5 on LTE though - not band 4. From some comments in the other thread, this may be why my speeds are slower??
Telus band 5 seems to be exclusive to BC/ Westside for now. Not sure if they expanded but I have never connected to it from the East end (Waterloo -> Toronto -> Ottawa).
https://en.wikipedia.org/wiki/Telus_Mobility#Radio_frequency_summary
What I do know is that I only get band 7 LTE in most of Toronto and Waterloo. It isn't that great however compared to band 4 coverage wise. Not the end of the world as it would just roll back to HSPA+ time to time.

The difference in speed should be because of Band 5 vs 4, my iPhone 6 connects to band 4 and I get around 80mbps+ down. My Mi 5 however gets around 40mbps connected to band 7.

Ayy another C-Townie.
Yes, Koodo's LTE band 5 covers the entire city. However, speed isn't that great since it has a max of 37.5Mbps. I usually get ~12Mbps.
The 150Mbps band 7 covers the inner city (up to Sarcee x John Laurie in the NW), but the max speed I could get is around 55Mbps.
Band 40 is a crapshoot and doesn't seem to have any deployment patterns to it, and it's slow as balls.
Hi all, i'm planning to get the Tencent version for 540$ (8/128gb to be specific) but i'm worried about the compatibility of the phone with LTE bands in Germany. If anyone have an answer, please share with me.
Thanks.
Check which bands your carrier uses and then check against the bands supported by the phone. You can get the LTE Discovery app and check which band you're currently using also.
How I can add LTE Band 20 to firmware?

If we are speaking about the 128GB/8GB version it's compatible as long as you dont need band 20 - e.g. if you are living in the city. The 512GB/12GB version also has LTE band 20. But both phones can be used in Germany.
