Nexus 5 LTE Band support

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.

[Q] What are the Droid phones sold as internationally

Hiya Everyone
Sorry for the question. In the UK we don't have the "Droid" brand name - no Verizon Wireless here.
Just wondering if they are marketed under another name in the rest of the world?
We have the Moto X & G over here, and like many others I am sure would like to look out for its arrival.
Thanking you all in anticipation.

AFAIK they are not sold as anything...VZW has the exclusive rights to sell Droid branded phones...
there is talk of a non-Droid variant of this phone that apparently passed through the FCC here in the states that would bring it to other carriers...that would be the device you would be looking for...but who knows how long (if ever) it will take to release...
apparently you can also have VZW unlock the phone so it can be used on GSM networks...might be something to look into...
this phone is quite the conundrum in that sense...when it launches, on paper it will be THE most decked out phone specs wise on the planet...yet it will be available (officially) through one carrier, in one country...VZW either has pics of Moto naked, or they really make a lot of money together

I think the one you're referring to is the "Moto X Play", which is a re-brand of the Droid Turbo, supposedly. When it passed through the FCC it had the LTE bands for T-Mobile and AT&T, which may be compatible outside the US.. I don't really know enough about the GSM side of things to be sure on that, though.

Fingers crossed cos it sounds like a Nexus killer

Droid always stays on US territory.
There's rumours about a At&t and Tmobile version.
i Recommend did what i did last year, i checked the specs of Droid maxx, i saw the bands were compatible with my country (mexico), and i saw all LTE verizon phones were unlocked and voila! i bought it and i was a happy droid maxx user on mexico even with LTE, everything worked perfectly.
this year its gonna be the same.
i recommend you to do the same.

Exactly what I'm wondering, I would be an N6 buyer but I've already had the big phones and I've come to the conclusion that at around 5 inch or a little more the extra size becomes more hassle to me than its worth. Not saying anything against these plus sized phones but they are not for me. I travel a lot though and I want a completely unlocked and unbranded phone. I'm hoping this one will see the light of day as an international version, if it does and its on kit kat I'm in.

At the moment I am seriously considering buying this LTE version if the bands are compatible and getting it shipped to the UK.
I too feel that the size of the Galaxy Note 3 / 4 is big enough.
Sent from my SM-N9005 using Tapatalk

I may have this completely wrong, if so, I will take any amendments in good nature!
Been following the Turbo for a while along with the N6 (which is just too big for me) to replace my N5.
Have investigated the issue of getting it unlocked (am with 3 on One Plan and no intention of leaving any time soon!) and shipped here and what bands it would use etc and this is what I have found (corrections welcome):
As far as I can see, in the UK, we use the following....
GSM
3 use bands 800 & 1800
EE use 1800 & 2600
O2 use 800
Vodafone use 800
LTE
3 use 20 & 3
EE use 3 & 7
O2 use 20
Vodafone use 20
The Verizon Droid Turbo has the following:
CDMA/EVDO Rev A (850, 1900 MHz)
LTE Cat 4 (Bands 2, 3, 4, 7, 13)
Carrier Aggregation (B4+13)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
UMTS/HSPA+ (850, 900, 1900, 2100 MHz)
So as far as I can see, it will work on on both 3G & 4G over here in the UK? If someone more knowledgeable could answer for certain, that would be a great help.

Hi Jason56d, If the phone is unlocked it may work, but we cannot guarantee that all services will be compatible.

[Q] Does Pure Edition support Fido/Rogers 3G/LTE bands?

I'm thinking of getting the pure in the US and using it up in Canada. Wondering if it'll work. I've heard mixed things about the LTE bands and some saying that 3G won't work at all.
Much obliged.

Telus sells the XT1097, your looking at the XT1095 out the US just don't pick the AT&T model as it has a locked boot loader that seems cant be unlocked at all..... The Telus model, supposed to have the quickest updates... well thats a lie.... there is no update as of today... and no indication of when either...

I was able to buy a XT1095. I still haven't received it but now all I can think about is "What if I need to use the warranty for some reason?". Did anyone in Canada have to go through that?

I asked a similar question (but for Telus) on howard forums. This is the response i received o0vL
"Moto X - Pure Edition (GSM Unlocked with T-Mo SIM - XT1095):

4G LTE (2, 3, 4, 5, 7, 17)
Telus Moto X Specs
4G LTE: (Bands 2, 3, 4, 5, 7,17, 29)
4G (HSPA): 2100MHz (Band I) / 1900MHz (Band II) / 1700MHz (Band IV) / 850MHz (Band V) / 900MHz (Band VIII)
Seems like the Pure Edition is missing band 29, where its available on the Telus version. Not sure if it will affect the LTE connection"

On another thread on this site, someone mentioned that the hardware is the exact same on the canadian model as it is on the pure edition model, the only difference is the firmware. So it seems to me that a radio flash might be required in order to receive the proper bands. I'd love confirmation on this, as I plan on using motomaker in the US to build my phone.

You can't actually change the modem files, you must you the original meant for the phone. The XT1095 supports all of the 2G,3G and 4G bands that Rogers/Bell/Telus/Fido/Virgin/Koodo/Wind/Mobilicity use in Canada. You don't need to do anything but insert your nano sim and possibly program the APN to get network data.

International Galaxy Note 5 N920i on US AT&T - Updates?

Hi,
If I was to pick up an international Note 5 (N920i) for use in the USA on AT&T, how would updates work? The theories I have is that either:
The device will never get updates
Samsung will release updates directly to the device
I will have to use custom ROMs for updates
Given that I will root the device (thus the reason for buying the international model), I'm assuming #3 will be the correct path. However, I understand I could run a modified kernel with the stock ROM to allow that, and there only seems to be one ROM outside of the carrier (AT&T/T-Mobile) threads. Could I use an AT&T carrier ROM?
I'm just trying to understand all my options if I walk down this path.
Thanks in advance.

So, if I was running a custom kernel for root, I would basically revert the kernel to stock, run the OTA or via Smart Switch, and then re-root. Sounds easy enough. Any idea what the timing is like for updates on international versions as compared to the US variants?

One other question, are you using it on AT&T in the US? The N920i says it's compatibility is:
COMPATIBILITY:
2.5G (EDGE, GSM/GPRS ) MHz:850, 900, 1800, 1900
3.5G (HSPA+, UMTS/WCDMA ) MHz:850, 900, 1900, 2100
4G (LTE ) Bands:1, 2, 3, 4, 5, 7, 8, 12, 17, 18, 19, 26, 28, 40
But Droid Life indicates that AT&T also uses a 1700Mhz LTE frequency, which I thought was only T-mobile: http://www.droid-life.com/2015/02/0...sm-cdma-wcdma-lte-verizon-att-sprint-tmobile/
Looking at the wiki: https://en.wikipedia.org/wiki/Cellular_frequencies it seems that there is a seperate 1700 mhz 3G and 4G. Does that compatibility chart above indicate that since it has Band 4, it has 1700mhz 4G?
Any thoughts?

And from another perspective, I consistently connect to AT&T LTE bands 2 and 17 using the n920c (which differs from the "i" in supporting band 20 and not 28 - neither of which involves at&t.)
The only frequency from AT&T that the 'c' and 'i' models does NOT support is band 30. At the present time, I think there are only two AT&T phones supporting that band (n920a and the at&t edge+)

When have you ever known at&t to be forthcoming with information?
Here's an FCC filing for the n920A showing band 30 support (as well as all the other bands supported for use in the US):
https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=2679337
(The n920a may supported other bands/frequencies, but the FCC filing won't show anything that isn't tested to work in the US.)

What I just found that's VERY interesting is that the n920i has FCC filings (FCC ID: A3LSMN920I) and the AT&T variant is obviously there (with FCC ID A3LSMN920A)
However, there's no sign of an FCC ID of A3LSMN920C. That would mean that my phone, the n920c, is illegal to use or sell in the USA. oops.
That makes things interesting, doesn't it?

I've been using the N920i on AT&T now for about two weeks and my speeds are excellent.
I tested LTE the other night on the speedtest app and had 50 Mbps download, fastest I've ever tested in my area (that even includes AT&T branded phones).
So no complaints here...

I concur with HNIC215. Had my phone about 4 weeks.

After realizing that this n920c is illegal in the US, I'm in the process of sending it back to amazon (and having it replaced with an 'i' model.)

Is there something about it not being cleared by the FCC that really bothers you or is it more of a just because kind of deal?

It relates to what I do for a living... I have a significant amount of contact with the FCC. It probably would never be noticed, but if it was, I'd be out of a job and possibly fined as well. The risk is too high when I'd be perfectly legal with the 'i' model.
Being that neither band 20 nor 28 is used in the US, the radio difference won't impact usage for me.

Makes sense to me, better safe than sorry when it comes to your job.

Has anyone tried enabling bands with QPST?

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.
One side note & a positive one at that:
My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.
IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.

i have MI MIX in hand.
I think we need MIX Diag Driver to make it recognize from pc. MI5 Diag drivers are not the same

I may have that 'xtra' mix in a few weeks, will PM you if it pans out and we can see about a software hack to open up other bands.

I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?

I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.
Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!

Good luck Ken, I hope you are able to crack this bad boy.

first of all I do not have the MIX/any Xiaomi device...but you could try starting here (though think you may have already or have plodded down the path much more already) good luck!

Is that band 4 only on LTE? I've seen many spec sheets and the carrier I'm on only has band 4 for 3g.

this is what I have gathered from various sources (so yes Band 4 is both LTE and 3g)
Tmobile
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
Lower 700 MHz band 12
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
ATT
AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands
LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz),
Band 4(1700/2100Mhz)
LTE B29 (700)
LTE B30 (2300 WCS)

That still doesn't mean the WCDMA Band 4 is enabled. It's possible to have LTE band 4 and not have WCDMA Band 4.

Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

Sorry to hear that the band could not be tapped into...
yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...
I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)
so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)
so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

can you make a detailed guide with all steps and stuff to enable desidered band ? If not works is the same ...

I would love to, it's the first thought I had when both starting a new guide and when I finished getting the phone to look for band 12.
I'm currently _buried_ in a project for work right now (it's taking my nights and a lot of sleep from me ha), so nothing soon. But it's on my list of first contributions I'd like to make to this awesome community!

Would you be able to try Band 20 ?
Thanks

So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.
