So, I bought my Mi 11 on a contract from some website I've never heard of and it was cheap. It's legit, but it's a US (IMEI number is region '05') phone flashed with a UK firmware. Are different regions of the Mi 11 built for different frequencies or do all Snapdragon chips support different countries?
Only because I've noticed it says I have like 3 bars of 4G signal but my mobile data just doesn't work and never loads. Like would I be missing on some 5g goodness too?
Also would there be anything I'm missing out on if the phone is in a different region?
Thank you!
I think the Mi 11 generally supports all bands. Perhaps the frequency selection is limited by the firmware. I haven't heard of any special UK firmware. There are 7 different ROMs. Actually even 8. The Vodafone ROM does not appear here. The last two letters after the number are decisive. Post it to you.
Just try the global stable. Maybe then your problem will be solved.
You could try to use the selection network options from testing mode.
Try using that method : https://itsitadda.com/how-to-use-more-than-20-network-types-in-your-miui-android-phones/
I have 5g but you have to remember that it depends on the provider and the 5g band the provider offers. My phone gets 5g with attnt and T-Mobile at least in the USA .

Hi!
So I've bought a Samsung S9 Duos recently and to be honest, although I like the phone and have been on a Samsung streak for the past few years, I'm getting seriously tired of their country dependant shenanigans. Because I live in Canada, when I buy a Global phone there's a bunch of stuff that either doesn't work or does only partially. And because the Canadian model is a SD proc, not an Exynos, it's an absolute nightmare to switch CSCs and get everything working right...
I hesitated long and hard to get a P20 pro, but the fact it wasn't available anywhere in Canada made me nervous. But my carrier (Rogers) recently announced it so, being really tired of this Samsung ****e, I'm considering returning the S9 and getting the P20 pro (even if it doesn't have a lot of stuff I like such as the headphone jack, SD card and wireless charging).
TL;DR
My question is, if I get an international (dual SIM) model of the P20 pro, is it going to be different than the Canadian one? Is there an equivalent of CSC codes with Samsung that I have to worry about, or can I assume it will be the same phone and I just need to activate it to get carrier specifics?
Thanks
I'm not an expert, but before I bought my P20 Pro, I made sure that it worked with the AT&T's network frequency bands. Each network has different bands and if the phone doesn't support the band, it won't connect.

Thanks for the input. I checked the bands for sure, and they are covered since it will be sold on my carrier soon. I guess what I meant is more the model itself, if there are variants per country or if we (Canada) are getting the same global version.
You see I come from a Samsung user's background and they have these silly country codes that dictate what you can use and where. I'm not sure it's related, but I found that even if on paper all LTE bands are covered with my S9, it still has shoddy reception compared to a Canadian S7. I could try to flash my CSC code to the phone, but a) it's complicated and risks bricking the phone and b) since the Canadian model is NOT the same as the global one, my CSC cannot be applied to this phone no matter how hard I try...

FunkyHuawei offers a rebranding tool, which changes the region of the ROM. I used it because I bought mine from a Chinese e-commerce website. I rebranded to European region.
I couldn't find anything about International or Global versions of the phone. I know they are region locked, but the rebranding tool will fix that. You can also flash a firmware from FunkHuawei or use HuRUpdater tool from TWRP custom recovery.
I have used both tools, and had 100% success.

Cool thanks, I'll see how this could help me out. I'm giving my S9 one last chance but short of that, I'll cough up another $1000 for this phone; I just don't want to end up in the same trap!
I didn't do my homework good enough and found out the uncompatibility (can't use mobile data, only voice/text) after I got the phone. I think I will need to flush the phone with a different ROM.
Does anyone know which ROM I should use, so that the phone will end up working with T-Mobile data network?
Thanks.
David
Are you sure?
I don't have this phone but I've had this issue with Xiaomi phones in the past, it turned out to be the APN settings.
I think it wasn't able to get the APN settings from the network, I found something online about my provider and it gave me 3G after I put it in. Then I found another APN for my provider and I got LTE working too.
k20 pro doesnt have bands 2 and 4
the newly released mi 9t pro (which is same as k20 pro) has bands 2 and 4.
i am not sure if Xiaomi has locked the bands on k20 pro with software or it's a hardware thing. if you can , return the phone

T-Mobile tech person was trying to walk me through to set APN. That didn't help. Eventually he asked for IMEI number and checked compatibility, which came back as only compatible with 2G for phone calls and texts.
Any moment 9T Pro firmware will be released, because the phone was released today so just way for it i think.

does the mi 9t pro firmware unlock the bands on the phone ?

I put a mi 9t pro ROM, MIUI Global 10.3.3.1 Stable 10.3.3.0 (PFKEUXM) on my K20 pro.
It boots up fine and runs fine, except, I can still not connect T-Mobile beyond 2G. When using a China Mobile SIM card (which connects to AT&T network), the status page shows HSPA,
So this seems to be a bad news, that bands 2 and 4, which are supported by Mi 9T Pro, seem to be hardware locked, that using a Mi 9t pro EU ROM does not unlock them.
Anyone has any other suggestions?
Thanks.
That is correct, hardware bands are locked into the chip and cannot be unlocked. Return the phone or sell it, if it really doesn't support the bands you require.
Btw. in which country are you? T-Mobile operates in many countries and with many different bands. Typically you should get 3G, unless you are in the US I think.
Yes, US. This phone supports Band 5 and I see Band 5 is on the T-Mobile support band list. But further check shows that T-Mobile uses band 5 for extremely limited use.
Oh well. Will look into selling it used.
Never purchased a non-US compatible device and had a question:
The China variant seems to have most T-Mobile bands (both do not have B71) as the global variant WITH THE EXCEPTION OF B66. Does anyone know whether this will be an issue?
Any help would be greatly appreciated.
i get my china variant Mi 11 Ultra on Monday, im on T-mobile and i live in NYC. i can report back to you then.

Lucky you! Yes please let me know how the reception turns out. I don't really care about 5G since it's not that widespread, but wondering how 4G LTE will be like.
If you have any opinions on the China variant as you begin to use it, please post as well! Also considering it since there is a cheaper variant (8G+256GB).
Any updates how CN version working in NY with T-Mobile?
interesting to see speed test on 4G. Is actually supporting one 5G band.

when i ran speed test i get 10Mbps here in Queens at my house. but the real test for me will be at my job, since i dont get any WiFi there.
I also did a factory reset (a habit i always do) and playstore disappeared, i looked on youtube for easy video to re-install. This is my 1st Xiaomi phone, so im getting use to MIUI. but hardware, much better than my Note 20 Ultra. the display is better and the frame rate i see it faster on mi 11. I plan to flash global ROM, but stuck waiting 168 hours for unlock to go thru. this is only my 2nd day with the mi 11 and i like it already. going out later to take some pics.
Don't buy China version because it doesn't support well Carrier Aggregation combinations used by TMUS so you don't get good speed from network. Also it missing B71 and B66 bands - common in US networks. 5G only works with n41 SA when available theory.
Here is list of supported bands and Carrier Aggregation combinations: https://cacombos.com/device/M2102K1C

Disappointed to hear you are only getting 10Mbps in a city like Queens. Do update is on what your down speed is like at work!
Thank you and good luck with flashing to global!
Is there somewhere I can view a map of which T-Mobile bands are used throughout the US?

I've used Chinese version phones without B66 for years, with t-mobile / google fi. Never had any issue with it. My wife uses an iPhone US version, I have stronger signal than her sometimes.

yes. the coverage in those areas are bad either with the US iphone or Chinese android phones with tmobile, imho. i only travelled to those places so i am not authoritive on this assessment.

Wow why the difference? What kind of speeds were you getting with other phones at home? Was it about the same?
My mi11 in China can work 280Mbps by 5G. Although the band is a little less, it is not affected in China
Is it a software thing that makes the band selection different between the two variants?
Is it possible to flash Global modem to China version to get the Global bands? or is there a physical difference?
OR
Does anyone think Xiaomi will come out with a 512gb global version in the future?
The different bands are hardware, there's nothing you can do about it.
Also, no, 100% they won't release any global 512gb version in the future.
Years ago there were some Qualcomm tools called QPST Tool and QXDM tool or something like that. I read they were used to "unlock" additional bands... But like I said, that was years ago, so no idea if it would work on the Mi 11 Ultra. Probably not.

Even if adding bands would be a thing...how many more does one even need? Basically all bands are there (except 66 which is prolly a us band).
It's cheaper for them to make one phone from a production standpoint than make ones with different bands for every market they plan to sell it in
I am gonna buy a Xiaomi Mi 10 Pro 512gb 12gb ram version, however there's no person ... "I just talked to our technicians, and maximum probable it's going to now not work and if it does then you will ...

hey there fellow XDA Members and Mi11 Ultra Owners!
Any downsides of buying the CN Version of this Phone over the Global/EU Version?
i've got the MiMix2s and have there the issue that it got some new Baseband FW someday that now produces issues in the EU Network... also other Phones from xiaomi had this issues that the CN Versions where somewhat troublesome
I bought the china version and when it comes to google integration, it's very limited what you have.
your apps and messages won't automatically sync, there is always the chinese apps that you can removed, but the AI stays there.. I installed the global version and it's like a normal google phone, everything will be download it to your Mi Ultra 11, no need to download each app individually, . If I was you, i would spend the little extra money it cost fot the global version and get it.
Just get the CN phone and flash the EU Rom.
Honestly I recommend buying the global version as internet bands differ from the Chinese version at hardware level, so no firmware can change that. Many people didn't find this an issue anyway,but I would recommend you to stay on global

I've not seen any changes to radio bands in any specs. I would have thought that they would not change the modems hardware antennas for different regions? If you have some specs showing the different bands can you let me see them or a link, I'm really interested if they have.

AFAIK bands are identical this year.
5G works here with CN model so I'm good.
Bands are different, sure you have 5g but you may miss something on some specific carrier
As far as I know, the hardware is identical
You can Check your location and carriers on kimovil.com
I posted a website where you can actually see the bands used by both versions,they are different, also on these pages in the thread "where to buy the mi 11 ultra" it's been posted many times, it's where I heard of it

But the hardware can select the bands from the modems configuration per sim and network location required to the maximum bands built to be used per model. See all the mi 11 ultra configurations in the screenshots taken from mine.
Mine is not rooted, but it would be good to see the modem config from a global hardware sold phone and a Chinese hardware sold phone both using the same ROM to see if there are any difference's in bands using the Qualcomm modern config app. I would be happy to be proved wrong but I bet both have the same bands, just applied different.
No rom or firmware can change the bands sorry
This is my first post so forgive any stupid errors or remarks ! I bought a Mi 11 Ultra with the CN Rom. I'm waiting for the bootloader to unlock and I was going to install the EU Rom. But I have been using it after taking off the bloatware and to be honest it's behaving and works well. The 5g speeds are good and it seems to change between 4g and 5g smoothly when moving about. I've attached a screenshot of a speed test done sitting in a coffee shop on Tottenham Court Rd London. No over heating and camera works well. So I'm seriously considering leaving it locked and using the CN Rom.
But willing to hear why that's a stupid idea!
Thanks

The CN ROM works well if you're patient and don't mind debloating and tuning it to ensure all Google apps work as it should since it does require some tweaking. For example, I remember my Google Pay didn't initially work.
I remember getting 150Mbps on LTE+ with EE in London Bridge station over a month ago which was fantastic although I heard the EU Weekly runs a bit more efficient with the memory management and process allocation. What eventually sold me was the fact that it was based on CN Weekly betas, and those occasionally get camera improvements first before stable across all regions.

I purchased the China version as well, maily because it is a lot cheaper than the global variant. I then wait a week, unlock my bootloader and flash the Xiaomi.eu rom with full Google integration. You see, the Xiaomi.eu rom takes the roms from China and removes all the Chinese bloat and script and then adds in full Google functionality. It's truly the best of both worlds.
