Hi, I recently bought a new mainboard for my mi 9 se from aliexpress, it is china version so some network bands are missing.
I have not problems, all works fine, but mobile data 4g max speed is 30Mbps, my old mainboard with the same operator was 200Mbps fast...
I installed MIUI 12.5.1 global.
The modem for china version could be different?
Thanks

Hello, I heard a rumour to use the new mi mix 2s in the USA you need to buy the 8gb ram/256 model?
Anyone know if that is true. I would prefer to use the lower versions of the mi mix 2s on T-Mobile in the USA but worried it won't work.

I doubt that's true. The bands are the same and the Mix2 works on both gsm and cdma (Verizon) lte. Since the new T-Mobile bands (band 60?) aren't widely deployed, I don't think you'll have a problem.

You should be fine...like the post above stated, the main T-Mobile frequencies are present. However, you will be missing band 66 and 71, the latter of which is becoming more and more important (the state of Wyoming, for instance, is almost exclusively band 71 on T-Mobile). Unfortunately it may take a while for Xiaomi or similar phones to support band 71 as it's been really slow in getting manufacturers to adopt this band, excepting Samsung, LG, and Moto. But in any case, all variants of the Xiaomi Mi Mix 2S do have the vast majority of T-Mobile's network covered vis-a-vis LTE banding.
It looks like all global versions of the Mi Mix 2S are compatible with T-Mobile LTE. But only the 256GB version of the Mi Mix 2S is compatible with Verizon. So if you're only worried about T-Mobile you should be fine.
I'm also in the same doubt..
Here in France we get the new b28 lte band, which is perfectly supported in the mi mix 2 whatever version, but in the 2s, it seems to be only supported on the 256 go/international version which is very very expensive!
But on some merchant (gearbest, aliexpress, etc...) the description of 64go global version say b28 lte band compatible...
Both 256go and 64go get the same cpu, snapdragon 845, and then the same lte modem...
So is there a chance to get a 64go global version compatible with this lte band, or could it possible to unlock the missing band with some tweaks???
In my location considering the li ited amount amount of 4G Bands the Mi Max 3 handles? I don't mind using ATT or T-Mobile but I am less then confident relying on their sale person's answers.
Thanks!

I use Cricket which is part of AT&T...so for 3G and LTE, both signals is quite spot on. I just got mly Mix Max 3 yesterday and i switch my sim from another Xiaomi device to give you an idea that Xiaomi Phones can handle that company, but you can go to Tmobile and have them test it out.

Global, but have tried Chinese Rom.. there is no difference.
Celmapper uses data collected by volunteers using the cellmapper apps for Android and IOS. It will show you LTE and GSM bands used in areas where volunteers have collected data. https://www.cellmapper.net/Index

I have exactly the same question:
According to official Mi Max 3 website:
LTE band support: B1, B3, B4, B5, B7, B8, B20
I just bought a Global version model: M1804E4A:
The user guide indicates band support: 1/3/7/8/20/34/38/40 (Bands 4 & 5 are missing !!??)
WIthout Bands 4 & 5 - I'm guessing I can't get onto AT&T and TMobile ?
ALso is there a code dialler to check what LTE band is being support by model: M1804E4A?
For folks using mi max 3 in USA successfully - may I know what is your model number?
Thanks !!
HI,
I operate a Note Pro 5 in the UK on the plusnet network which uses the following bands / frequency's. I use the global ROM
800MHz band, the 1800MHz band, the 2100MHz band
Iam not having much luck with the 4G speed / connection. Iam wondering if that's because the handset does not work with these bands. No point reformatting my phone only to find out if the phone does not work with these bands !!!
Thanks
Mathew
It should work fine, as they use EEs network. I use virgin mobile that also uses EEs network and its fine. Have you tried amending the APN settings?

Yes you are correct Virgin and Plusnet both run off EE but its not that simple.
EE only allow some bands to be avalible for resale the ones I have listed are what Plusnet use.
You have pointed out something I should have done!!!! I have removed the APN and started from scratch I will try this for a few days and see what happens.

So from what I've read plusnet don't seem to offer the 800mhz frequency (EE/virgin do), but if your Redmi Note 5 is the global version it will work with all UK 4G bands (including 800 or band 20 if its available from your provider). Usually band 20/800mhz travels further and so tends to be used more in rural areas to help improve coverage. Were you connecting to 4g OK before or have you just changed to plusnet or just got your RN5?

Yes I thought that but have had conformation directly from Plusnet that they do use the 800mhz range
@MathewRB
Global version of Redmi Note 5 supports all frequences You mentioned. The only problem is that it doesn"t support carrier agregation (LTE+) which can lead to slow data acces when the transmitter which Your"s phone is connected to is clogged

Thats a good bit of information looks like Iam finding more and more of reason (excuse) to upgrade to the 7 Note Pro. But when is the 8Note Pro due to come out any idea?
in my country we have 2 versions of note 8
one is made in india and the other is made in china
and we have a local 4G provider which offer just LTE data network ( no calling or messaging )
the chinese version recognize this network and data over 4G works normally but the Indian version doesn't
the Indian version doesn't even see network even if we flashed it with global chinese rom
any suggestions?
Thank you
Hi
I bought a 11x from India and I trying to use it in the UK. The coverage is very poor due to the bands being use by India rom. Do you think there is a way to improve it.

The bands are picked by your sim card not the phone. If I stick in my AT&t sim it always uses band 4 for LTE. I have the Poco F3 global edition working in America and I have the international Samsung S10 lite working same thing band 4.
Then using the same sim .. in s21 and m11x why do I get two different data speed. My understanding was Mi11 was using a different band to s21.
