Im actually okay with that....when will the 3gb version be available?
I want to buy Xiami Mi4c. I live in INDIA.
Does anyone know if this device will be launched in INDIA or not ? Any info on this will be appreciated.
Also my colleague is travelling to China, so will it be a good idea to get the phone from China ? Will it have international warranty ?
Any support for 4g in the uk?
Anyone tried buying from the actual mi site and getting delivered to a chinese shipping address?
All those resellers have a significant mark up and/or limited color choice.
I thought I might get someone I know who speaks chinese to do it, I cant see much downside but ... you never know.
I think the phone would be the same right? Its not like theres an english version.

Efox is good
Also cect-shop, but i would go with efox

The Chinese version should be no google play included. You can get your device rooted and download a "谷歌安装器" app to install google play services. That's how chinese users install google play services.

Yes, it supports bands 3 and 7 but not 20 (so no dice on Vodafone)
4g support
on ibuygou they state on the product page that the phone supports both 4g networks (FDD and TDD)
Does anyone know whether it's supports both lte-FDD and lte-TDD?
I know it's dual sim, but do not know whether there is only 1 version of the phone that supports both 4g standards or that there is a specific version of the phone for FDD and a specific version of the phone for TDD.

Ah thank you. I cannot read chinese so I couldn't figure that out from the product page.
In that case it's a really nice phone. Snapdragon 808, FDD and TDD.
Any of these companies have warehouses in Europe to save on custom charges and a better returns service if needed?
Here in Italy I know at least two well estabilished web-stores that import China devices (not only Xiaomi) and sell them with a "proprietary" warranty service.
They are TopResellerStore.it and SmartyLife.net, while both have excellent feedbacks I personally purchased from the former with good satisfaction.
Hope this helps.

According to the official specs from Asus, the Zenfone 3 Ultra supports LTE bands 1/3/5/7/8/18/19/20/26/28. However, they also state "ASUS phone 4G/LTE band compatibility varies by region. Please check compatibility with local carriers If intending to use your ASUS phone outside the original purchase region".
According to Gearbest's page for this phone, it supports LTE bands 1/2/3/4/5/7/8/12/17/18/19/20/26/28/29/30.
Is Gearbest getting their version of the phone from a non-standard region, or is their info page incorrect?

You should reply and have them test it on tmobile and or Att.
I can't wait for this phone to work in the US. I'll have a blast learning development on it.
The company OnePlus should finally take care of the full support of VoLTE and WiFiCall at the three major German providers (Telekom, Vodafone, o2). So far even the flagships do not support any of these technologies, although on the hardware side all prerequisites exist and the technology is also advertised in Germany in the hardware specifications.
Explanation
OnePlus has developed the OnePlus 6, a very competitive product that does not support the simplest communication technologies, at least in Germany.
These would be VoLTE and WiFiCall. In India, these technologies are supported. In Germany, with identical hardware, but not. This is due to the reluctance of Oneplus to implement the techniques correctly and completely.
Important are the mentioned technologies for users with little to no reception in the 2G and / or 3G network. Telephone calls could be transmitted over the LTE network, or WLAN. However, this is not possible because of OnePlus itself.
Inquiries concerning this problem are answered via ChatBot, with the immediate answer that there is no agreement with e.g. the telecom would exist.

It does not work. Over 500 supporters who tested and reported it is not working. As the text says: the technical infrastructure is there, but does not work.
Dont working for me with Telekom.
Even if both, the device and the carrier, support VoLTE or VoWIFI, it doesn't necessarily work. Usually a carrier firmware is needed. Some carriers offer VoLTE only to phones sold by them. For example, I'm in UK and on EE. Beside my OnePlus 6 I have an unlocked Galaxy S8. In order to have VoLTE on my S8 I had to flash an EE branded firmware.
All in all, this petition should include those carriers too and not just OnePlus.

Its not like that anymore. Xiaomi is not even sold officially by Telekom, o2 or Vodafone in Germany and still they have these features.
Oneplus just needs to implement it, but they don't.

maybe everyone should check these paths with a (root) file explorer:
data/vendor/radio/modem_config/mcfg_sw/
firmware/image/modem_pr
read file "mbn_sw.txt" it's a kind of listing for the deeper paths.
in my opinion you could check if your COUNTRY/CARRIER combo is the lucky one....just check the china path... VOLTE voila!
.../generic/eu.. does have data for "ee" "elisa" "telefoni" "h3g" "telia"....but not for every country...
could anyone in here confirm that O2 / UK give your OP6 VOLTE super powers? anyone from great britain here....

Just checked on mine (German). In this file there are these paths yes, but in my version there is "china" alsways the "volte" term in the path.
With all eu carriers there is no term "volte" in the path... might not play a role, but at least it's a difference in the wording....

I've managed to get vowifi and volte working with the VoEnabler module for magisk. Everything works surprisingly, but for some reason my phone won't recognise incoming phone numbers properly when on these services, resulting in unknown/private number.
I have a feeling its something to do with the radio modem files that you've linked, but no luck so far. If I manage to get it working I'll follow up.
It's annoying as Huawei and xiaomi phones have over 100 entries in their mbn_sw.txt file, whereas oneplus has only a dozen or so... Ive come to the conclusion that, in the UK anyway, the phone manufacture has more to do with this than the carrier..
Sorry for the formatting, at work on mobile
I'm sure the question will get brought up......
The answer is yes! This phone works perfect on Verizon. Lte , calls, mms all work flawlessly. You must already have a active micro SIM and just swap it from previous phone to the NEX
This is only for the s (sd845 processor) variant that supports the bands of cdma and lte.

I think VOLTE is like T-Mobile's band 12, 700Mhz concrete break through band. The phone has to be authorized by the provider for the service to work.

I can't remember if the Service Dialer code *#*#4636#*#* works on the NEX.
If it's capable,you should be able to see if the toggles for VoLTE & Vo WI-FI are accessible (not greyed-out).
Just curious,as neither are available on the NEXs' cousin,the Find X.

3 questions
1. Is your Vivo Nex the 8gb ram version or the 6gb ram version? I heard that one of the two models do not work well with Verizon, so i want to know the model you use on Verizon if what i heard is true.
2. Did you buy the Chinese version or the India version of the Vivo Nex?
3. Where is a good place to buy a Vivo Nex? Is it possible to have the website where you got your Vivo Nex if you got yours online?
Ran into this info unrelated to your VOLTE problem but it deserves a read. Looks like IMS, which can be added in the APN settings, has to do with VOIP.
The settings location is APN TYPE located in your APN file @settings\Mobile Network\Access Point Name.

Hi guys,
I received an offer to order a Chinese Oneplus 8 and 8 pro however I am wondering if I can use the 5G here in the UAE.
Our networks support 5G, however, I need to know if the Chinese version OnePlus 8 5G will work.
Is there any bands like LTE that we can check. Or the 5G in Chinese version will only work in Mainland of China?
Thanks guys
hi dear, if you are referring to the ones sold on noon by callmate, they are definitely rebranded chinese variants, and you can check the 5g bands from oneplus spec sheets
https://www.oneplus.com/cn/8/specs?from=8
https://www.oneplus.com/ae/8/specs?from=8
i see that on https://halberdbastion.com/intelligence/countries-nations/united-arab-emirates both of your du and etisalat should work on 5g at n78, and looking at the above spec sheets, n78 is supported on both ae and cn models, so i guess yes it should work.
I might be wrong, so take it with a grain of salt

WOW! You got what I am thinking. Yes, I am planning to order from Callmate. However I am think if I should buy it this early. Oneplus 8 and pro is now flooded with screen issues in Oneplus forum. What do you think? I am thinking of buying OP 8, Mi note 10 pro or Realme x2 pro. Mi 10 price is crazy high here also so it is not on the option. Last option for me is iphone SE 2020.

Not to start a new thread, so trying to post the question here.
I got a Chinese Oneplus 8 Pro from an online sight who have stated that they've flashed it with the Global Oxygen ROM.
Thing is, while the sites state the 5G Bands that the phone supports, 5G does not want to work out of the box in my country (Saudi Arabia) even though my Huawei P40 Pro used to show 5G at home.
I've read somewhere that someone has purchased a similar phone and has managed to connect his phone to laptop and do a couple of things and get 5G to work.
Could anyone possibly point me in that direction? I have honestly searched for a few days but yet to find a way of activating 5G here.
Cheers in advance.

Hey thanks for your work on it. I've found that QPST up to 2.7.480 does not support the 8 (No Phone, but device manager sees it properly. I've also tested QPST with my OP6 and it's fine). Which version of QPST did you use?

in carrier_policy.xml you can change policy to enable 5G, modify 4G CA Combinations and enable/disable single band support certain PLMN.
Amazing, I can confirm that 2.7.460 works, but 480 does not. That said, can modifying carrier_policy.xml result in enabling bands that NV has locked? I assumed that adding bands required modifying the nv section?
Edit: Enabled additional bands via lte_bands section, but it didn't work (downgraded to 3G instead, no LTE bands shows up)
