Need help figuring this one out. I just got last week while visiting Illinois a P30 Pro L04 that is from Telcel Mexico. Got it from a coworker that lives in Mexico. It is unlocked and I am using in T-mobile ever since. I live in Puerto Rico where Tmobile has Band 4-66-71 for LTE. My previous phone is an Note 9 that I love and still think is better in some ways that the P30 specially in the software side. The cameras in the P30 are spectacular and step way above the Note 9. Long story short my P30 won't connect to band 66, only band 4. It is supposedly supported but it doesn't connect to it. I put my sim card back in the Note 9 and it does connect to band 66 as it used to. So it is definitively the P30 Pro problem. Does anyone know a way to verify what Bands are supported on the phone and see if it Telcel that blocked the band 66. Or maybe the P30 does NOT support band 66 as claimed? Does anyone has a L04 and can connect to band 66? I am new to Huawei phones and don't know what tool are available to verify this things.
I think you might be seeing 66 on your note, but it still really 4. (4 is a sub frequency of 66)
The 66 you're referring to will specify AWS-3. An app like network cell info on the play store should specify - though will likely only work on the Note assuming it's the snapdragon variant.

Do you care to elaborate a little more so I can fully understand. Yes my note 9 is the snapdragon variant from Tmobile. I am using the Network Cell Info Lite App and it does show connections to LTE bands 2, 4, 66 and 71 on the note. depending on the place I am around my apt or outside. The P30 Pro only show connections to LTE bands 2 and 4 connections. I understand that bands 66 and 4 are related as they are the same frequencies , but still band 66 should give me better speeds and better connection as shall be not as congested., more blocks, etc. The Network Cell Info (at least the lite version) does not give me anything about the AWS of the band.
So my questions for you or anyone else are:
Are you saying that band 66 won't show on the P30 Pro even if it is connected to it?
Do you know of an engineering menu to really verify that the phone support band 66?
One of my main interest and one that may help a lot of people is to establish if the phone really support band 66 as claimed for this variant?
and if it does, does Telcel disable that support?
if they did, maybe with a generic firmware modem we can get it back?
Thanks in advance

I do not currently have a P30 Pro, so can't speak definitively. (Sold my L29 and have an L04 on the way) I asked about the snapdragon variant because these devices are generally the only that will properly break out band information for you to look at.
The answer to your question is a bit convoluted due to the fact that band 66 includes band 4. These are the AWS bands - band 2 is PCS, 3 DCS, etc. Some devices may tell you that you're connected to 66, but you are in fact connected to 4. (see here for a better definition: https://www.phonescoop.com/glossary/term.php?gid=570 ) If you look closely here, you will see that band 4 and 66 include the same frequencies, but 4 is specific to blocks A-F and 66 includes blocks A-J. Say, you're connected to block C, your phone could be telling you that you're connected to 4 or 66 - both would be correct, its just how the manufacturer has told the software to relay this information.
What you're wanting to validate is that you're connected to the "new/faster" part of band 66, which will be displayed as AWS3 for AT&T. On the RAW tab within network cell information (on your note) it should have the band info and then corresponding block information. If your Note is reading 66 (AWS13) this will probably show as band 4 on your P30 Pro, as it is technically .. band 4. If you are seeing 66 (AWS3) this means you are genuinely connected to the part of 66 you're after. If you see this on your Note and your P30 Pro is still showing band 4, I would suspect that your theory regarding P30 Pro band 66 support is correct. (aka.. not functioning)
Hope this helps.

Yes it helps a ton. I had to buy the full version of the Network Cell info to get the AWS information, not showing the Lite version.
The note 9 is reading band 66 (AWS13) in Tmobile. With the same simcard and location the P30 reads Band 4(AWS1). So I can't really say if the P30 Pro it is not connecting to band 66. I guess will be good if you give me a follow up once you get your P30 Pro L04 and you happen to be in an area with "real" band 66 support.
Thanks because I am sure this info is good for those that has this variant, or those that want to get one especially if its going to factor into their decision.

For sure. I also bought the L04 variant for B66, so I'm hopeful that this band is indeed active. I will let you know what I find out.
Let me know if you run across AWS3 to validate too.
I've had my L04 P30 pro all over Chicago and St Louis the past few days (in areas I know have b66 coverage) and have yet to see the device pickup it up once.
My only thoughts are that the device only activates b66 once properly provisioned by Telus on their networks, or that AT&T will only tell certain devices to grab the band that they know have proper hardware for. (Internal database of devices, etc) I'm genuinely curious if any Tmobile people are able to pickup the band; generally Tmobile is more lax about these requirements.
Either way, b66 isn't supported on AT&T on my particular L04.

At least in different place in Puerto Rico it is the same, only band 4. I shall be in Chicago area also probably in like a month and in Mexico. Will take my note 9 with me to make sure I am in AWS 3 to see if I get band 66. if not then something is right with the phones having band 66 blocked.
Thanks for the update

Where can I buy a international note 5 for germany?
Thanks
seems its available in singapore, anyknows where it can be bought online
Yes, it is available in Singapore... I bought mine in a samsung-shop on saturday. Not sure about online ordering.
Maybe you can try here...
http://www.expansys.com.sg/mobile-phones/brand/samsung/
check ur PM
Does anyone know which Version Supports german language and celluar bands?
Hey, I have not looked at asian note 5 yet, I will do so soon.
For Europe, you need gsm and lte 3, 7, and 20 (1800, 2600, 800 MHz) [no26-800MHz # no20-800MHz! ...]
To use US phones for Europe, this is what i have come up with.
http://imgur.com/1yPhyFQ
I based that on what I found for SM-N920 A/V/P (AT&T, Verizon, Sprint), German/UK LTE network requirements, and the Galaxy S6 (SM-G920 A/V/P/F, F=Europe/Int). I guess the Note 5 is pretty much a S6 with larger screen and pen, so network capabilities should not differ too much between the S6 and the Note 5, hopefully.
I will get a AT&T device soon, hopefully only bootloader unlocked and just KNOX (don't care too much about warranty for US phone since I import it...). AT&T should work for most of Europe, or respectively for LTE 3, 7, and 20....
I see what I can find for the Asian Note 5 ('s) and msg back
EDIT:
Haven't found much info on the SM-N920S / SM-N920K (Korea, Asia?), but based on the SM-G920S/K or Galaxy S6, versus the SM-G920F Europe, there are some minor differences, but I think these should work just fine in Europe as well... http://www.mobosdata.com/samsung-galaxy-s6-sm-g920f (k, s).
g/l
Ill also need to import one, since it wont come here to brazil...needs to be lte band 7...id like to buy it today if possible...
How you can use a Galaxy Note 5 from U.S in Europe? is the region block...
the at&t one, unlock via website, not straight forward potentially, but seems possible espc as non-customer - https://www.att.com/deviceunlock/
but what bothers me is this: http://forum.xda-developers.com/note5/general/verizon-att-samsung-note-5-knox-root-t3183641 - i guess will hold off the note 5 at&t for now, same with verizon, and sprint might not have full lte capabilities.
i might get the surface phone lol (if i can get full access to registry and group policies and have some way of turning all the phoning home off)...
Man, why you speack about Note with carriers?
On eBay there are a lot model FACTORY UNLOCKED, are they good? they have the region block if i buy them and i use in Italy?
I have the singapore one.
And it works just fine here in the netherlands.
At my home I don't have 4G.
Outside there is no problem.
I think the singapore one misses the 800 band.
4G is working only in the big cities here for now with this note 5.
Later this year the phone company release another bands.
800Mhz is to 1800 and 2600MHz LTE - loosely compared - as 5GHz Wifi is to 2.4GHz -- higher transfer speeds at the higher frequencies but shorter range and less signal through obstancles, generally speaking.
Would explain why inside you would not get a great LTE signal, if the 800MHz band is missing.... imho
You are right.
But the seller told me the 800 is there.
And now I know there is not a 800.
But here in the netherlands the provider also uses the 1800,but only in the big cities.
That's why the phone picks up 4G when I am outside.
yh, most european countries use all 800, 1800, and 2600, depending on region/area/whatnot...
just saying, without 800 capability, and when you happen to have 800 mast outside your area, you might not get signal, especially inside... ofc you can still have lte via 1800 and 2600, provided you are close enough and have a mast nearby, more likely in the cities (lots of data over short ranges)
Still I am happy with the note 5.
I am not saying anything about that
Apart from the obvious things everyone knows about vs the Note 4, it's a great looking piece of kit!
Also, Seller MIGHT have said 800 is there, as in 800MHz B26, but what you'd need in Europe is 800MHz-B20...
I saw it on ebay.
It's 800 B26.
My mistake.
I don't bother.
I read about Samsung region block and we can't put a different SIM respect the SIM of the contry model. Don't you have problem?
Does anyone have an SM-N920I?
It probably has more / less bands than you think. What's posted online doesn't actually reflect much about the actual phone. Does anyone have an SM-N920I?
In your dialer could you please type *#2263# and naivate to Band Selection. Post here what's in WCDMA and LTE.
On the S6 SM-G920I:
WCDMA: 2100, 900, 1700, 850, 1900
LTE: 1,2,3,4,5,7,8,12,13,17,18,19,20,25,26,28,29,40
on my N920I I have the following:
WCDMA: 2100, 900, 850, 1900
LTE: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 21, 25, 26, 28, 29, 30, 38, 39, 40, 41
Let me know if you want something else too.
I bought this device to use on AT&T in the USA. So far it is working perfectly.
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'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.

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),

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).

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.

can you make a detailed guide with all steps and stuff to enable desidered band ? If not works is the same ...
would like to see if LTE Band 20 can be unlocked

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.
Wanted to post that on Verizon and Samsung website the LTE bands supported on the device doesn't not include bands 12 and 71 that T mobile uses. Well i have used it on T-Mobile and it connected to band 12 which leaves me to believe the Verizon edition supports all bands like a unlock model would. Single and bands 2 4 and 66 worked great and are the main ones used in my part but 12 is around also and connects. Don't have any area where there is band 71 so cannot test that but like i said probably does just wanted to pass the info.

Hey bud
I just started using the Samsung galaxy s10 5g verizon variant with tmobile and had band 71 in the band selection app but today I checked and the highest band it has now is 66. Why did band 71 disappear from the lte band list?
Would you know about that?
Thanks
Nevermind, figured it out.
I'm looking to replace an Honor 8 with a Mi 9. The phone looks great, but I was wondering if anyone was using it on T-Mobile in the US? It has most of the LTE bands, but doesn't have 66/71, so I was wondering how well I could expect it to work?
And how is Xiaomi about rolling out updates? Huawei released monthly updates for six months, then would slowly release last month's security update every 3-6 months before stopping at the 2 year mark. If I buy the Global version will OTAs become available based on IMEI? Or is there something region specific?
My Mi 9 just came in yesterday, and I'm on T-Mobile in the USA. I can confirm that volte and wifi calling works if you follow https://forum.xda-developers.com/Mi-9/how-to/wifi-calling-volte-mi-9-t3917887
Band 66 and 71 are both a big deal. Where I currently live there will be no band 66 or 71 anytime soon, so I didn't mind buying a phone without these bands. The phone before my Mi 9 didn't have band 66 or 71 either. That said, there are some parts of the country where band 71 deployment is happening rapidly. I don't travel often so it's not a big deal. If I did travel often I would definitely want band 71.
Now If I paid $600 or more for the phone I would expect the phone to have band 66 or 71...
I'm on Mint Mobile which uses the T-Mobile network. Reception is great where I live (Chicago) but if you need bands 66 and 71 I think you would need to look for a phone that is specifically made for use in North America. Most global unlocked phones don't support those bands.
I am with MetroPCS, live in Indianapolis and my speed and reception is all over the place. I have the unlimited data plan but I am not sure if I am being throttled or not. I've literally run a speed test back to back in the same location and I will get two very different download speeds. I am not sure if it is the phone or network.
For instance, I have 3/5 bars but my most recent download speed is 4.83 mbps. Unfortunately, I have no way of comparing this with another phone bc my previous phone was a s6+ and I think the radio was going out. However, I can confirm that VOLTE and wifi calling work.
I really wish this phone had band 66 and 71, but I knew it didn't have them when I bought this phone.

Looks pretty good, but no wireless charging, no IP rating, and the color balance between the 4 camera lenses is WAY off. Hopefully ZTE will fix that with an update.
Seems weird they sell this phone in the US while not really supporting US bands.

I have T-Mobile. Not limited on 4G-LTE whatsoever. But yeah, only 1 5G band supported. No 5G in my area anyway so I don't care about that. AT&T will also work just fine.

?? It's lacking b66 and b71. 71 might not be that important unless you are out in the country, but 66 is aws and is super important these days.
While I'm not that familiar with att, it's still missing 2 out of 5 bands

You're confused. It works on 5 out of 9 ATT 4G-LTE bands (all of the major ones), and it works on 4 out of 6 T-Mobile 4G-LTE bands (all the major ones).
