i reply in english because for forum rules the answer can be erase for be in other language lol. yes i can... i search a lot and i buy mine on amazon, i asked to the seller and he said it works on all except 4G band. anyway in my area don't have 4g so.. no problem with that if you want to buy on Chinese page you can enter here http://www.kimovil.com/es/donde-comprar-xiaomi-redmi-3s-3gb-32-gb and you can se the web sites where the phone its sold with that band enabled. i hope you understand my bad english xD

I am from Mexico and bought my phone at geekbuying webpage.
[HK Stock][Official International Version][Package B]XIAOMI Redmi 3S 5.0inch HD 4G LTE MIUI 7 Qualcomm Snapdragon 430 Octa Core 3GB 32GB Smartphone
This International Version Works perfectly with 4G LTE Band 4. (Telcel Mexico)
Movistar in Mexico Uses the LTE Band 2 and the phone will only work with 3g. (H+)
Hope this helps.

Seems like the international version of Redmi 3s has additional FDD LTE bands (4G: FDD LTE B1/3/4/5/7/8/20 (2100/1800/1700/850/2600/900/800MHz)). I am wondering if we can unlock the additional bands in our Redmi 3s Chinese version because I also need band 4 in order to have LTE signal.

I was trying to unlock Band 2 on my phone, but could not unlock the bootloader.
After being granted permission from Xiaomi to unlock bootloader, I get the "Couldn't Verify Device" Error at 50%. Seems this is something xiaomi needs to fix.

VoLTE in German Vodafone network. Anyone got it working?

Hi everyone,
I'm using the Redmi 3S internatinal with band 20 (800 Mhz) LTE. Now I switched to Vodafone, becouse they support VoLTE. But Unfortunately, I don't get it working - even on MIUI stable, it's not working...
What I did:
- Installed the latest global firmware (v0.51)
- edited all apn's after each other and then together to support "chap"
- advanced LTE services are enabled...
Has anyone been able to use VoLTE with Vodafone?
Officially the R3S is not supported by Vodafone...
Thanks everyone!

You got it working? I have the same problem, on Telekom. I tried several roms that should support VoLTE, but does not work...
You have more infos? Thanks!

4G+/LTE+ or LTE Advanced

Hi all. I open this thread because I have a Redmi Note 7 which in Xiaomi Spain (the website) stated that it had 4G +. I've been testing for months and only have 4G + with the b3 and b1 bands. Does anyone know if this problem can be solved? I am in Spain where there is 4G + with 1800 + 800 and other bands and I am not able to connect to them.

You're using stock or custom ROM? If custom ROM then it is probably a bug.
Here's a screenshot of my phone running Bootleggers ROM with 4G+ enabled https://imgur.com/gallery/GLZ8Go7

TicWatch Pro 4G LTE do not works with Bulgarian operators anymore

Hi to all!
Few days ago I found my TWP 4G can not connect to A1 network anymore.
Do someone have an idea what changed? Is the problem in the A1 provider or the problem is in some TWP update?
I am tempted to install custom rom to the watch, but if the problem is in A1, it will be waste of time.
Regards!
