Hello friends,
I have an FDD-LTE MI4 and I live in Brazil.
I realized that the MI4 only works in the bands 1 and 3 of LTE, whereas in Brazil using the band 7, is there any way to unlock the other bands in MI4? I saw that this procedure is possible in other cells, but found nothing about the MI4.
I await response, and now thanks.

Pity no one has idea about this one. More xiaomi are vailable now throw sellers but it seems the LTE bands will not satisfy much countries.
I am in France and as you, if I buy I will not benefit from LTE...
I heard non-mtk models do support other bands but are locked because of licenses, don't know if true
Hello I'm French and in my country the carrier use the B1 B7 and B20 to connect to network.
But all the xiaomi not use the B20 radion
I see it's possible to unlock B20 for smartphone use Qualcom soc ?
I don't know if is possible to unlock the B20 for the Xiaomi Mi4c ? It use a Qualcom 808 soc.
Please help me for use the B20 in the Xiaomi Mi4c

Unfortunately you can't unlock band 20 at the moment, in fact you might not ever be able to unlock the band. So if it's crucial for you to have band 20, buy a different phone.
However, it's a really nice phone, if if you don't necessarily need the specific band, then this phone is a good buy I believe.
ok thank's a lot
@ggkameleon,
I don't have this phone (yet ) But, my Telco uses Band 20 too.
What I intend to do is use my sim for phone calls/TXT's and get a 'Pay As You Go' LTE sim for Net access.
If you see the most good chines provider don't use B20 Mezu Xiaomi Lenovo why ? And other use it but it's not the more good smartphone or huawei use it but the price are expensive. When you see the last Xiaomi Redmi 3 Redmi note 3 and now MI5 very good smartphone and not expensive.
Hi din't know what is it a 'pay as you go' ?
But if your telco use b20 you can't have 4g lte in b20 ! But if use with b20 the band b7 or b3 the phone connect to b3 or b7 if ist possible or connect to wcdma in 3g network !
But i can't know why meizu pro 5 use the same soc exynos than galaxy s6 and the galaxy s6 work in b20 ! It's not possible to unlock b20 in meizu?

He meant he'll use a second, prepaid sim to get LTE from another provider who uses a different band. Although it's been said that using the dual sim function on this phone reduces battery life quite a bit.
Yes, if you don't have the correct 4G bands, but do have the 3G or 2G bands, your phone will be fully functional, just not have the best speed possible.
It's not just a matter of having the same soc, it's a combination of soc, radio and firmware. In some phones a workaround can be found to unlock the radio, others not.

Ah ! Ok but if they are a provider don't use B20 go it ! Don't use two provider ? Ok it's not possible to unlock.
Me in my country (France) They are 4 provider Free use 2600 for 4g, but it's a new provider and they are not many radio in 4g and even less 3g I test it's not possible. Bouygues use for 4g 1800 2600 and a little 800 it's the best for chinese smartphones but where I leave there are not radio Orange use for 4g 800 2600 and in radio there are two band in city but in campaign only 800 Sfr use 800 2600 and use a lot of 800 and it's actually my provider. I speak with users of chinese phone the best are Bouygues or Orange because the one don't use many 800 and the second if don't possible to use 800 the phone go to H+ (wdcma 900) and the speed of 4g 800 it's the almost the same of H+ wcdma 900 !?
If I buy a Xiaomi or Meizu I do change my provider but the smartphone do use the 3G Wdcma 900 ! I believe do use it.
The problem now it's Xiaomi block the boot loader of the new phones ? I see the new Redmi note 3 Pro it's a more good quality but It's more complicated to change language and don't use B20 ! I'm disappointed.... I stay to see what Xiaomi make for international customers.

Ok i understand
Yes it's not a good idea to use 2 different provider one don't use b20 and one use it !
Because if you have a provider don't use b20 go for this provider Because you paid 2 provider ! It's just if you are in contract you can make this option but it's more expensive.
In France all provider use b20 ! Only one don't use but there are not enought radio.
Thank you for your message I understand it's to complicated to unlock band and it's possible to use only in 3g.
Yes, too complicated or simply not possible with the hardware. Whatever the case, 3G can be more than sufficient.. I have never done anything with my phone that required more speed than 3G.
However, the phone does have a lot of other LTE bands, be sure to double check if there's not one that matches, it was the case for me.
1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)
https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe according to this, there should be enough in france that match to provide normal LTE operation.
Free Mobile is fine for Mi4c you know
I have LTE in outdoor in all Paris (indoor i'm always on wifi)
Thank you for your support and link
Actually my provider are Sfr (because I have a promotion for one year 10€ calls/sms unlimited ans 20go of data) and I do not want to break this wonderful contract
This provider use fifty/fifty FDD B20 800mhz/B7 2600mhz and UMTS B8 900mhz/B1 2100mhz
That good for Xiaomi Meizu FDD-LTD except FDD B20 800mhz
But there are a new problem with Chinese smartphones the Boatloder are lock now
I use Apple phones after Samsung with 3gs 4s and 5s but now the price of their phones are to much and not as high as the difference of Use Android phones ! It's stupid now to buy a smartphone than 800/1000$ it's not possible to my heart and my wife said go out of home if you buy it !!! Paid us a travel and buy another phones. she's right you know.
I like Xiaomi phones and I stay for the mi5......

Wat about other bands ?
i used also my Mi4c with 2 SIM cards (one private with Free operator and the second one with SFR for pro usage). No real problem with 800mhz band used by the two operators.
Ok thank you

The problem will be in a zone where the SFR antenna will deliver 4G only on the unsupported band, you will have only 3G.
That'all. So, it's up tio you to test in the main zone you are, what bands are used by SFR.

Yeah i read all that ...i was hopiing
thx tho....i can still use band 7 here LTE is doing great ...band 4 would be nice for full coverage especially inside building and metro ...
I bought Xiaomi mi4 64 gb from china last year. To my surprise only 2g network was connected and no 3g and LTE. I don't have much idea about it. I live in India, forget 4g, if there is any method through which I can connect my phone to 3g band I'll be grateful. If someone can explain me how to unlock all 3g bands and that will possibly connect the 3g band of India, it will be of great help. I have already used the phone in 2g network for a year and it's pain in the @ss. I found recently that by unlocking it is possible to use global bands. PLEASE HELP!!!!! THANK YOU!!!
Did you buy TD-LTE version? FDD-LTE is used in most countries.
Most probably YES
Probably Yes. Otherwise the problem of network might not be there.

Have been using Redmi series of phones for a while. My son plans to be in US for 13 months. Indian Note7 pro only is compatible with two LTE Bands in US that too only from T Mobile and with one LTE Band of AT&T.
https://www.kimovil.com/en/frequency-checker/US/redmi-note-7-pro is the link I used to check compatibility.
Even Mi A3 Indian version got only 2 LTE Bands, same as Note 7 pro.
Wonder if anyone knows if there are other LTE bands enabled, but not listed? Also, if there is any mod by which you can enable other LTE Bands like B2 and B4?
Any info will be really helpful.
use QXDM tool to unlock bands
