Xiaomi Redmi Note 4X - Not working on FDD 900 MHZ - Xiaomi Redmi Note 4 Questions & Answers

Hello,
I have some questions regarding Xiaomi Redmi note 4,
I live in Peru and bought the mobile phone through tinydeal webpage. I specified that I want a mobile phone FDD LTE 3G 1900 mhz and 4G 900 mza (Band 8).
Unfortunately I received a product without band8, so I think I received the xiaomi redmi note 4X. The cellphone has 3Gb RAM, 32 GB ROM, Snapdragon
the mobilephone box does not have info regarding internet bands, my question is, how to identify the correct model with FDD 3G 1900 and 4G 900 mhz?
Do you know what can I do to confirm if my mobile phone has 4G in 900 mhz? I asked directly to Xiaomi official and they could not confirm and suggested to ask directly to the customer, unfortunately the customer did not provide the info.
Do you know if mobile phones are like laptops where you can see RAM, ROM, internet bands?
Thank you ,
Pierre

BUY Oneplus 2 $459 64 GB from Oppomart - Works Tmobile LTE

After seeing it one oppomart for 459, i found 3 listings on ebay for $435 16 GB or $459 64 GB from oppomart that ship from china. i just ordered mine. I also chatted with tmobile, and they said the phone will support tmobile lte and hspa+ bands.
16 GB:
Mod edit: Links Removed
64 GB:
Yeah, just realized that. I canceled it and reorder from oppomart for $459 for the 64 GB black edition
Ordered the 64 GB from oppomart with a glass protector. shipping was $30 for 7 days, so total with everything was $496!
U do know there 16gb and only 3gb ram
Yeah, just realized that. I canceled it and reorder from oppomart for $459 for the 64 GB black edition
Yup I ordered mine yesterday
Comes with crappy Hydrogen OS though, doesn't it? You might end up waiting weeks or even months before someone gets a US OnePlus 2 and creates a flashable Oxygen ROM from it, so why not just wait to get an invite and save some money in the process?

It works on T-Mobile for sure?
That's what T-Mobile rep said. I chatted with one online and gave them the bands to confirm

Would you mind sharing it ?
I am stuck with Hydrogen OS
It does not work on tmobile LTE. It will work on 2g and 3g.
Who knows for sure? Is Oppomart shipping the international version
with OxygenOs 2 and LTE compatibility?

yeah it won't work on T-Mobile LTE, their bands are 4 and 12, the oppo opt LTE bands are 1,3,7 (china version.
there seems to be a USA version of opt which supports bands: 1/2/4/5/7/8/12/17
There seems to be 3 versions (that I have seen so far), China, USA, and rest of world.
however it still needs to be confirmed if the hardware is the same between all versions, like the opo and just needs a utility to unlock additional bands.
Problem solved!!! I got this official answer from OppoMart suppport team:
"hello,
yes, the phone from us comes with oxygen os 2.0 and google play store installed,
and support GSM: 850/900/1800/1900MHz , WCDMA: Bands: 850/900/1900/2100MHz,
LTE FDD: Bands: 2100/1800/2600MHz., which can be used in your country.
Please feel free to contact us if you have any question.
Thank you and regards.

So here you have it. This is an intenational device like the one sold in Europe and the USA.

NO it is not the international version, it is the china version. Which only supports three FDD LTE bands 1,3,7
Band 1: 2100MHz
Band 3: 1800MHz
Band 7: 2600MHz
That's just a china version with Oxygen OS installed. You will still not be able to use it on LTE in USA.
My guess is they get china versions, open them up and install Oxygen OS and then sell them.
btw there is a difference between the version sold in USA and Europe as well.
I got better price for this product, pm me if you want to get it cheaper, with free shipping...thanks.

What I gather is that even the Global OP2 does not support 4G in the USA on the major networks which mainly use band 2,4,12/17 (AT&T/TM)
OnePlus 2 Europe/Asia model supports the list of FDD-LTE and TDD-LTE bands:
1 (2100 MHz)
3 (1800 MHz)
5 (850 MHz)
7 (2600 MHz)
8 (900 MHz)
20 (800 MHz)
38 (TD 2600 MHz)
39 (TD 1900 MHz)
40 (TD 2300 MHz)
41 (TD 2500 MHz)
OnePlus 2 North American model supports the list of FDD-LTE bands:
1 (2100 MHz)
2 (1900 MHz)
4 (1700 MHz AWS)
5 (850 MHz)
7 (2600 MHz)
8 (900 MHz)
12 / 17 (700 MHz)
Hopefully they all are hardware identical and a sodtware fix can unlock all bands

kudos for finding the time to put list up all the different supported bands. hopefully its the same situation as the OPO and we can unlock the other bands.
We went through this last year with oneplus putting people off buying a Chinese version, all sorts of discussions went on about separate hardware on different production lines, in the end the only difference was the rom and cyanogenmod logo.
I ordered mine from China last year and its still going great , and i´ve just ordered my two from oppmart.

Where to buy global/international version?

Hello all,
I just saw the review of this phone @gsmarena.com (SD version) and it called my attention because of the supported frequencies (850,1900 2G/3G and B2/B4 LTE). This is the only Xiaomi phone with support for the carriers in my country. I have looked online but all the stores only have the phone with unsupported frequencies, similar to those of the MTK version.
Does anyone know where to but this phone with global band support? Thanks.

But i think you will not be able to flash all that custom Roms Herr...cuz this is the Kate Version not kenzo...thats why ill order the standard Version i think..
Thanks, that's what I was looking for. Is this site trustworthy?
How do you identify what variant of the phone are they selling? Anyways, the one there is the only one with LTE support for my county.
My other option is the ZUK Z2, but have read very mixed reviews, thus I'm leaning towards RN3.

Hello,
I'm a bit confused about frequency support, as information across sites is not consistent.
From what I' ve read in the forums, there are 2 models:
- Kate, LTE B20 support
- Kenzo, no LTE B20 support.
Most sites sell a version that has no B2, B4 and B20 support, and that would be Kenzo, right?
Some other site lists one with B2, B4 and B20 support, that would be Kate.
But then there's another one that has B2 and B4 support but no B20. Which one is this? Are there different different versions of Kenzo? Is the site spcs incorrect?
Here are the sites and variants:
* B2, B4 AND B20 Support, Kate

Goldway has update his item description, now it claims to support B20.

I think that Prime ver means for all of them 3GbRam/32Rom.
Right now what I check is weight, 167 gr mean kate aka Special Edition
Regardss.
Pd. Careful since maybe cases are bit "tightly" (2extra millimeters)
Another supplier. Ships form an EU Warehouse. Support said, if all goes well, they will have stock next week

My suggestion where get it
I bought from HotMID(dot)com for Xiaomi devices and verified them physically and on mi(dot)com/verify.
Well, I finally made a decision and boght the one from geekbuying.com, which would be Kate.
From whats I've read in the forums, is supported by CM, which is what I would use. I've never used MIUI before, I'll give that a try frist.
My phone should arrive in about a month...

I ordered Mine too from geekbuying but kenzo, I don't need Band 20 but I like flashing and development. I already got the MiPad2 and used it with AOSP for a while(Stock Android) but then they released MIUI 8...And yea I still use MIUI and I love it, I recommend to install the Rom from xiaomi.eu it's globalized and has some other nice optimazions ull love it! Let us know when urs arrived.?
Naily
I received my Kate yesterday evening. So far I like it, MIUI is strage, needs some getting used to. Seems like the ROM is the factory one and has not been tampered with by the seller. I got a notification about OTA Update and it installed without a problem. I'll install the developer ROM today if I got the time and apply for bootloader unlock.

Does Redmi Note 4 SD work in US?

I would like to know if Redmi Note 4 can be used with US carriers? I am moving there and was planning to buy a phone
Redmi Note 4 Supported Bands:
2G bands GSM 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 3(1800), 5(850), 40(2300)
US Supported Bands:
2G capabilities GSM 850, GSM 1900
3G capabilities UMTS 850, UMTS 1900, UMTS 1700, UMTS 2100
4G capabilities LTE 700, LTE 800, LTE 1700, LTE 1900, LTE 2100, LTE WCS 2300 (30), LTE 2500
Doesn't look like it but I wanted to know, since some users have claimed that they are able to use 3G despite the band being unsupported.
Get the ZTE Axon 7, Supports USA bands. I wish I did. To answer the original question. The note 4x works on at&t in the US, only one band. Band 5, sucks. So its not as fast as it could go but it at least works slow.
I have a Redmi Note 4X international edition and I'm running on the T-Mobile network. I'm in Utah. I couldn't give you the detailed channel info but you can always check the site http://willmyphonework.net/ it's a pretty good site to check phones against networks. That's what I did before I purchased my phone.

Don't know. I don't have a data plan.
I'm using the Redmi Note 4 global edition on T-Mobile and I get LTE on band 4.

Where did you buy it?
Is the LTE just as good as any other phone or is it ****tier in some way?
I don't understand why more people don't use them here if they work just as good, since it's clearly the best phone out there under 200 bucks, as far as I can tell.
I ordered a global version, but I still don't have any confidence that it's gonna work based on what little information I can find on the internet.
I'm on T-mobile US, using a Redmi Note 4 Global, and I've had no issues with it. Good LTE speeds, but I can't get VoLTE to work though.
Screenshot of my speeds here: http://imgur.com/h7So6Sj
yeah, I've been looking at apps like LTE Discovery the last couple days, and it looks like there's plenty of Band 4 in town where I'm at, so I guess that's good. Usually the places I go when I go out of town have no lte anyway so I doubt I'll be missing much.
I don't mind not having VoLTE since I use like 10 minutes of voice calls a month and I don't think my current phone uses it anyway.

What are the Model #'s for Snapdragon 625 [Note 4] & [Note 4x]?

Good day, everyone
TL;DR - WTK Model Numbers for Snapdragon 625 [Note 4] & [Note 4x]
So far;
2016100 = Redmi Note 4 4Gb/64G (credit: @sachin n)
2016101 = Redmi Note 4X 3Gb/32G (credit: @Delkapone)
2016102 =Redmi Note 4 3GB/32GB (credit: @krasCGQ)
I am about to finalise the purchase of a Xiaomi Redmi Note 4 OR 4X.
I am trying to find ONLY the MODEL NUMBERS for;
Xiaomi Redmi Note 4 - 4gb RAM, 64gb storage (Snapdragon 625 Variant; might be 2016100 or 2016102, need confirmed)
Xiaomi Redmi Note 4X - 4gb RAM, 64gb storage (Snapdragon 625 Variant)
Some threads have said the SD 625's of both the 4 and 4x and identical, yet others go on to state physical differences in feature/hardware placements.
I just want to ensure that I get the Snapdragon 625 version, I do not want to end up wit a device that has the Mediatek CPU.
P.S.
Please don't turn the question into an argument for the Mediatek Variant and/or the 3GB models and your experience with them, I've already decided on the Snapdragon 624 4gb/64gb and I'm just trying to ensure I get the correct product.
I understand that the model numbers may vary slightly, possibly dependent on region and storage configuration.
I've looked for the questions/answers in the forum and others as well and can't seem to get a straight idea.
Thank you everyone, any relevant constructive help will be greatly appreciated.

Double post, sorry :c
SD 625 is octa-core while Mediatak Helios X20 is deca-core. Some shop list it, I think it's a good indicator to buy the right version.
And I also read something about that the differnt SD 625 versions have difference only in supported network frequency.

Thank you for responding.
I do know the SD625 is an octa-core vs the deca-core of the Mediatek version.
I've already decided on the SD 625.
The problem I am having is that I was told in passing that the NOTE 4 SD625 (4GB/64GB) is identical to the NOTE 4X SD625 (4GB/64GB).
I am just trying to find a way or confirm if there are physical differences or not.
They are identical, the only difference is that the 4x doesn't have b20(800 MHz) band...But some shops
report It in the specification, I think it's an error...
I don't remember where i red this, but another difference is in the Quality of construction that in 4x is lower than 4 ( I don't know if it's true)
The Redmi Note4x is the global (or international) version. It has 4g lte radio bands that will work on either AT&T or T-Mobile in the U.S. The Redmi Note 4 will not work on any 4g lte band in the U.S. It will work on 3g band 1900 which is supported by AT&T and T-Moibile but you can forget about 4g lte in the U.S. with this version. The 4X was released about 10 months after the 4 version was and there are some hardware differences because of that (different brand sensors and camera's) but don't confuse the the different SOC options (MTK or Snap) with one version or the other. You can find both of those SOC options on either version. Even though there are some brand differences in the internal hardware the X of the 4X version is simply meant to signify that it is a global use phone with additional radio bands that the 4 version does not have. BTW, the IR blaster is not in the same position so if you are buying a case or other accessories, buy the case that is specifically for the 4 or the 4X version.
This comparison chart came directly from Xiaomi....
The Differences
Redmi Note 4
Bluetooth 4.1
Network Bands
4G FDD-LTE B3 / B5
4G TDD-LTE B40
3G WCDM 850 / 900 / 1900 / 2100MHz
Redmi Note 4x
Bluetooth 4.2
Network Bands
4G FDD-LTE B1 / B3 / B5 / B7
4G TDD-LTE B38 / B39 / B40 / B41 ( 2555-2655MHz)
TD-SCDMA B34 / B39
3G WCDMA B1 / B2 / B5 / B8 (850 / 900 / 1900 / 2100MHz)
CDMA2000 / 1X BC0
2G GSM B2 / B3 / B5 / B8 (850 / 900 / 1800 / 1900MHz)
The Note 4 is made in India and the Note 4x is made in China. The differences in bands on the chart above reflects the needed bands to work in China. Since they posted this chart they have also added lte bands that work in the U.S. (band 4 and whatever AT&T uses) but did not update the chart to reflect that. All newer Note 4X's are global 4G capable though.

Bands of Honor 9 (Europe)

Hi, i'm about to buy the Honor 9, but I have a problem. I will buy it in Amazon (Europe) and ship it to my country (Argentina) that uses this bands:
2G (EDGE, GSM/GPRS): Bands 850 / 1900 MHz
3G (HSPA+, UMTS/WCDMA): Bands 850 / 1900 MHz
4G (LTE): Bands 4 (AWS o 1700) / 7 (2600) / 28 (APT o 700*)
(the most important band is the B4 AWS, the others are not that important)
And I searched on google and I found differences, some places say it has the b4 band(frequencycheck.com,phonedb.net), others say no (gsmarena)
Amazon says its the model 51091SNW, but assume is the STF-L09 version
So I need your help, if anyone of you has bought this phone in Europe and wants to confirm if it has the band that I need, I would be grateful. Otherwise, I'll have to choose another phone because a phone without 4g nowadays it's not good
Thanks in Advance!!!
I checked the price comparison I usually use and which is usually pretty well informed (this is their English page, the company behind it is originally from Austria):
Frequency bands: GSM (850/​900/​1800/​1900), UMTS (850/​900/​1900/​2100), LTE (B1/​B3/​B5/​B7/​B8/​B20)
https://skinflint.co.uk/a1638115.html
Same info from my go-to review site (translated from a German review):
Networking: 802.11 a/b/g/n/ac (a/b/g/n/ac), Bluetooth 4.2, GSM 850/​900/​1800/​1900, UMTS B1/B2/B5/B8, LTE B1/B3/B5/B7/B8/B20, Dual SIM, LTE, GPS

Both is for the STF-L09, which is sold throughout Europe, so I guess it doesn't matter that both have their info from devices from Germany...
It seems to lack Band 4, and according to gsm arena it does so for all Honor 9 models available
