Mi4 LTE bands - Xiaomi Mi 4

Hello, I am looking for some help regarding 4G support on the Mi4. The FDD LTE version of Mi4 is listed as supporting the following:
4G: FDD-LTE : BAND1/BAND3(2100/1800MHz)
TDD-LTE : BAND41 2496-2690MHz
2G: GSM 850/900/1800/1900MHz
3G: WCDMA 850 / 900 / 1900 / 2100MHz
I have seen posts about the WCDMA version, but does anyone know what chip the LTE Mi4 has?
Does the fact that it supports some FDD LTE bands mean software can be used to unlocked it for other FDD LTE bands, such as 800 and 2600?
Does the fact that it covers the 2600 band under TDD LTE mean software can be used to unlock FDD LTE on that band?

[Q]. Need to know Model vs 3g bands used

I have been looking in many different places and could not get a decisive result towards which E8 model has which frequecy bands, especially concerning the 3G bands.
I hope one could give us a conclusive answer to this.
I myself have an M8sw chinese dual sim E8, and I still cant tell this answer wether I have
850, 1900, 2100 or
900, 1900, 2100 or
850, 900, 2100 or
850, 900, 1900, 2100
And I could not find one conclusive answer to this.
Please if someone can link each model to its bands, I would be extremely greatful.

Ian, I guess tou are the one, when it comes to E8. Thanks.
Just one more question. How did you figure it out?
You speek Chinese? The site has no English version. I thought I could use it for reference, but unfortunately I coudlnt due to language barrier.
Use Google translate, man...

Radio / Bands support in Europe?

hey guys,
i can't really find any information if the Mi4C will work out of the box in europe. i'm in austria on a drei (three) network.
i've read stuff about LTE/4G not being supported in europe but thats dismissable for me. but will normal phonecalls and connectivity up to hsdpa+ work in europe?
thanks in advance
According to gsmarena

So check your bands with this
Three (3) only works with bands 2600 and 1900 so they'll both work in the Mi4C. The only band that won't work is the 20 (800 mHz)
I posted some guides on how to unlock LTE bands in here: http://forum.xda-developers.com/mi-4c/general/unlocking-lte-bands-t3215763
Hopefully those instructions work for someone to unlock B20. Let me know if it works!

[Question] Moto G 3rd Gen International Network Compatability

Hi all, I'm considering buying an unlocked GSM Moto G 3rd Gen, and I am trying to figure out how it will work outside the US with other network operators. The 2 areas I am interested in are Hong Kong and Ecuador.
The network specs for the Moto G 3rd Gen are:
Code:
Technology GSM / CDMA / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900
CDMA 800 / 1900 - XT1548
3G bands HSDPA 900 / 2100 - XT1541
HSDPA 850 / 1700(AWS) / 1900 / 2100 - XT1540
HSDPA 850 / 1700 / 1900 - XT1548
4G bands LTE band 1(2100), 3(1800), 7(2600), 8(900), 20(800) - XT1541
LTE band 2(1900), 4(1700/2100), 5(850), 7(2600), 17(700) - XT1540
LTE band 2(1900), 4(1700/2100), 5(850), 12(700), 17(700), 25(1900), 26(850), 41(2500) - XT1548
Speed HSPA 42.2/5.76 Mbps, LTE Cat4 150/50 Mbps
GPRS Yes
EDGE Yes
GSM information from: http://www.worldtimezone.com/gsm.html
China, Hong Kong (SAR):
Code:
900 1800
3G 2100 CSL Ltd; 3G 2100 HKT; 3G 900/2100 Hutchison; 3G 2100 SmarTone;
4G LTE HKT 1800/2600Mhz; 4G LTE Hutchison 1800/2600Mhz; 4G LTE SmarTone 1800Mhz;
Ecuador:
Code:
1900 850
3G 850 Claro; 3G 2100 MOVISTAR;
4G LTE CNT Mobile 1700Mhz;
My conclusion from the data above is:
Voice/SMS/2G Data - Supported in both HK and Ecuador because the Moto G supports all 850, 900, 1800, and 1900
3G Data - Supported in both HK and Ecuador on all carriers since all frequencies for the carriers are present in the phone specs for 3G
4G LTE - Supported in both HK and Ecuador on all carriers because all frequencies listed by the carriers are present in the 4G LTE list
Could someone eyeball these specs and let me know if I'm drawing the correct conclusions or if I'm actually misunderstanding how the bands work?
Any help is greatly appreciated, thanks!
Edit: I was double checking the bands listed on gsmarena, which claims both Hong Kong and Ecuador have UMTS 3G bands. The Moto G specs say HSDPA for all the 3G bands. Does the phone need to have UMTS listed for it to work or are they compatible for 3G?

Samsung Galaxy S8 Compare Network Frequencies and Data Type

I’ve been looking into buying an S8 and the fact that each carrier has its own Galaxy S8 variant made me do some research to make sure I pick the correct phone variant.
I wanted to share this with you guys to hopefully have an aggregated listed to help make someone’s life easier when it comes to deciding: is this frequency supported by this model of S8 or will I purchase the phone and end up on certain bands or frequencies only!
Note: The source of this information is Samsung corporate websites only. No third party website was used. And all credits go to Samsung for properly listing their specs. I just aggregated them in one place to be able to compare them.
Please note the US/North American carrier unlocked model will be released later in May.

Thanks for sharing... and it's neat to compared..
i was looking to buy a International version for tmobile, and most of the comments across multiple forums are B12 support is not there for Tmobile..
but the specs says it supported all of Tmobile bands, should anyone has good experience on this..
the specs mentioned is almost matched with most of the sites i referred, hopefully exynos version support tmobile bands..
Commodore Thanks for the info especially the important reference I've been scouring the internet trying to find the one that fits my needs. Any way is there any frequencies for the US unlocked version? Thanks

US unlocked or carrier free version has model number SM-G950UZKAXAA.
It's listed on bestbuy's site but the network specs don't look reliable, for example the lte bands and the lte frequencies don't match up. I will wait until this phone model gets listed on Samsung's support website and go with those specs. They might drag it out until the end of the month to sell as many carrier S8's as possible. Carrier free is probably not on top of their priority list. But since it's on top of my list, I will wait until the end of May and not limit myself to one carrier specially since this phone is so expensive. (And so cute too ...)

It's from a new MVNO using Verizon's network, hasn't launched to subscribers. Probably why you can't find it and why I am having problems getting premium care from samsung too. Lol

Ok thanks for the update . So the new mvno probably hasn't even started listing the phone on their site. Something like Credo Mobile perhaps.
TDD LTE bands B38, B39, B40, and B41 on SM-G950U
Commodore 64 said:
US unlocked or carrier free version has model number SM-G950UZKAXAA.
It's listed on bestbuy's site but the network specs don't look reliable, for example the lte bands and the lte frequencies don't match up. I will wait until this phone model gets listed on Samsung's support website and go with those specs.

Samsung's website for the SM-G950U: https://www.samsung.com/us/mobile/phones/galaxy-s/galaxy-s8-64gb--unlocked--sm-g950uzkaxaa
The webpage lists the FDD LTE bands in the specs, but it does not list any TDD LTE band at all!
I bought an SM-G950U from best buy a few days ago, but given the issue of reliability of specs that you mention, I want to find out (before the return deadline) if the TDD LTE bands listed in the first post are really supported on the SM-G950U.
So, how can I reliably confirm that the SM-G950U supports the TDD LTE bands B38(2600), B39(1900), B40(2300), and B41(2500)?
Solved, using dial code *#2263#
Danny Noman found the solution: Dial code *#2263# lists all active LTE bands on the phone, and on my SM-G950U1 galaxy S8, it shows TDD LTE bands 38, 39, 40, and 41.

Can i buy Chinese OP7 and flash Global ROM?

tittle says it all
is there differences in band support? Im from brazil
I bought my 5T and flashed it from H2OS to OOS using local upgrade, no problem.
Seems OP7 supports all frequency bands in Brazil. But you should check with your carrier before getting it.
