b20? - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I looked at EU sellers and all mi 9t are k20, not k20 pro. So I looked at Chinese sellers, but no k20 pro I found supports band 20? Is that correct? Will there be mi 9t pro or something? If so - when?

The K20 and K20 Pro, so far, have only officially been released in China so only have Chinese bands and so don't have band 20. The Mi 9T is the international version of the K20 and had extra bands opened up. So far the Mi 9T Pro is only a rumour, but seems likely, though some rumours say it will be released only in Russia. There are also rumours that the K20 Pro will be released as the POCO F2, but this is less likely. Whatever happens, nobody knows when a international Pro version is going to appear.
If you want the Pro version and need band 20, then you'll need to wait and see. However, do a bit of research and see if you can live without band 20. For example, in the UK, it would be possible to use it on the EE network mostly and suffer only in rural or heavily built areas. But all other UK networks rely more heavily on band 20 and so would not be possible to use the phone.

Chinese version does not support band 20

Will K20 Pro work in NZ?

I'm a bit confused, they are going on about the 9t Pro coming out for Global market, but on Aliexpress there is a K20 Pro with 'Global Rom'.
If i was to buy one of these would it not work in New Zealand? I'm really keen on getting this phone but not sure what to buy.
According to this, it works perfectly with my provider 2Degrees

The K20 Pro does not have global network bands. Where it's sold with a global ROM, these are unofficial global ROMs, they do not and cannot add extra lte bands.
The Mi 9T, as well as coming with an official global ROM also had a few extra lte bands unlocked. The Mi 9T Pro will do the same, when it eventually arrives.
Looking at your carrier, it uses bands 3, 7 and 28 (maybe 40 too, but could have been a different NZ carrier). The K20 Pro is missing band 28.
Band 28 is a relatively low frequency band, these can travel further and penetrate obstacles better, before losing significant signal strength and quality. Quite often the low frequency bands are used in rural areas, where masts are spread widely, or major city centres that are very heavily built up.
NZ is a very sparsely populated country, so it's possible band 28 is heavily relied on outside of the town's and cities. But this is only my slightly educated guess. I would suggest doing some more homework on how much of the 2Degree network relies on band 28.
I imagine in and around towns and cities you'll have very little issues, but that's a small percent of the country.
Assuming the Mi 9T Pro will have the same bands as the Mi 9T, then it will come with band 28

It says that 2degrees doesn't use B28, only other carriers in NZ. So that would mean its safe to assume it would work?
Thanks

I checked on Wikipedia, however I was looking at the bands for Spark by mistake. 2Degrees uses 3, 8 and 28.
https://en.wikipedia.org/wiki/List_of_LTE_networks?wprov=sfla1
Band 8 is on the K20 Pro and is also a low frequency band. So it could well be that it will work OK. However it is showing that band 8 was added to the 2Degrees network only last year, so might still be wise to see if you can find out how widespread band 8 is used on their network.
Edit:
A bit more reading. The 2Degree website FAQs confirms it uses the above 3 bands. Band 8 was previously used for their 2G network, but was freed up when they turned off 2G, which allowed them to use it for LTE. Maybe that will mean it's use is widespread.
I'm not sure about nz but it works perfectly fine here in Australia. The only band we use in Aus that it's missing is B20 which is very common. But fortunately if you're with Telstra in Aus they don't have any areas that only run on B20 so there's always something for me to connect to. I also live in a rural area.
So my advice is to check different areas all over nz to see what they support. I used a site called cellmapper to do this https://www.cellmapper.net

Not sure about NZ, but in Australia it works. I'm with ALDI mobile which I guess is Telstra.

I've gone ahead and purchased it as of an hour ago excited to get my hands on it, this makes me even more confident as your bands are the same pretty much. Can't wait!

Australia use band 28, not 20.
Global version and chinese version are using same 4G bands so there won't be any problems.

Xiaomi redmi k20 pro UK networks

So I've just bought thr 256gb/8gb variant and it did say on the website that it is compatible in the UK, I'm on EE and that is a supposed supported network, just wondering if they're are any people in the UK on here who gave bought the k20 pro variant and not the mi variant and how the network coverage has been? Any feedback will be great

I'm in South Wales with the K20 pro model and have had no issue at all!
I travel a lot with work and it's fine.
EE doesn't use the band's that are missing between the K20 pro and 9t pro so you'll be fine :good:

There's only 2 way intra band CA on k20 pro (band 40 + band 40) , even if its there in India, no significant increase would be obtained.

No 4G reception on Vodafone UK

Hi everyone. Hope someone can help, I have a redmi k20pro and cannot seem to get a 4G data signal. I put my wife's o2 sim into the phone and it gets 4G straight away, then when I put my sim back in it gets 4G for awhile then dissapears again. Can anyone maybe help or know what may be wrong ? Thanks in advance

800mhz and 2600mhz seemingly ?
Then that's the problem, K20 Pro doesn't have the important LTE bands for Europe especially B20 and B28, Perhaps O2 have a band which K20 Pro has. You were better buying Mi 9T pro and not K20 pro which has the European bands

I can manually go in and select Vodafone 4G UK and it works then will eventually revert back to H+
Then maybe the signal is weak?

EE is your best bet, all bands are covered in the K20 Pro.
Vodafone and 3 should be OK, they both use B20, which is missing, but they both also use other bands extensively too. It does sound like you're unlucky and in a weak signal area.
O2 will give worst coverage, as they used to only use B20. They've added other bands in major towns and cities so will get some coverage now, but you'll not get 4G once you go semi-rural and beyond.
Can confirm EE works really well, I get 4g pretty much everywhere, Voda uses band 20 so for sure you will have issues
this is because Vodafone UK mostly relies on Band 20 which the K20 Pro does not support. For the best 4G reception go with EE as they mainly use B3 and B7

Can Redmi K20 pro flash Xiaomi 9T pro's software thus unlocking LTE bands?

I am think about buying Redmi K30 pro and use it in the US. I was told I should wait for the international version because of LTE bands. But I am thinking if this kind of unlocking mechanism can be done on the predecessor, I don't have to wait. Thanks!!!
It's not possible to unlock LTE bands on K20 Pro like it's not possible to do it in any newer phone.
