I do have a chinese version of Mi 11 Ultra . Even though before i bought the phone i read all the 4G and 5G bands are supported for UK , it looks like 4G connection is very weak on Giffgaff network , which basically runs on O2 architecture.
As the bands are 100% supported , is there any way i would get normal data speeds ? Dont even dare to think at 5G . I would be happy with 4G+ . With Giffgaff only get 3mb/s speed while tested ID mobile and have 18mb/s .
So will the global or EEA rom fix this problem ? Can this be fixed by software or not ? I am confused and not sure what to do, try to sell it of keep it . Thanks in advance .
With the GG SIM in another phone side by side what do you get?
( In my village we can only get O2. So we are with sky. I'm lucky if i get 5mb here. O2 / sky have no CA / 4g+ in my area. That said , a few miles away I can pull 400mb 5G. )
I just did it now on a different phone which is nowhere near the quality of Mi 11 Ultra and i just got 19.6 mb/s on giffgaff network . Same network , same location . Mi 11 ultra gets close to 4 mb/s while old Huawei phone gets 19.6 mb/s .

My bootloader is not unlocked so i guess i cant install global yet . Currently on Chinese 12.5.2 ROM .
So far no one has installed global and confirmed if 4G+ is now working where it wasn't on the CN version.
I'm tempted to try it but then I read about rollback protection and so many issues, can I downgrade from 12.5.2 EU Stable to 12.0.1 Global?

Try putting the sim. In slot 2 and run another test
The problem here is that chinese device haven't channel aggregation unlocked for european providers..
Might be worth a try flashing Global firmware to know if modem.img part could unlock it.

Hi all,
I just bought Mi8 China Set. the problem is my telco support 4g+ and in my place have coverage of 4g+ but when i put my sim on my mi8, there is no 4g+. only got 4g.

I'm using stock rom 10.1.2.0 global on unlocked bootloader
Using miui 10.3 xiaomi.eu 8.12.27 also no works.

I recently read about this on the MIUI forums. Apparently, the phone does support 4g+ but xiaomi has intentionally disabled it.
I don't have 4g+ in my country so It's not a big deal to me but you can go find it in the forums and vote for xiaomi to enable it.

MIUI is a mess because they have region-based settings and features.
Some things work for some countries while they don't for other countries. It's messed up. Xiaomi needs to fix their ideology on what MIUI should be.
This phone is probably the last time Xiaomi is seeing my money simply because of their dumb android skin...

Mi8 chinese has b20 too, the real problem of this device is carrier aggregation. It aggregates some bands that don't guarantee lte+ in all country
Hi Everyone.
I'm on a new Xiaomi mi 9 for 2 weeks, but slow download speeds in 4G/LTE mode is killing me.
Speedtest gives me 1.2MB/sec
On my old Oneplus 5T, i got results from 5 to 8 MB/sec.
I searched a bit on the net but couldn;t find this issue for Mi 9. Anyone arround here had this issue ?
P.S.: i have Band20 working on my phone.

See what bands your carrier supports and compare it to your mi 9's bands
Also, what ROM are you using?

Seems that Vodafone romania is using band 1, 3, 20 (2100,1800,800). As i see in LTE Discovery, all 3 bands are used sometimes.
When i bought the phone it was on stock MIUI 10 and the problem was present. After a few days i got announced that MIUI 11 is available and i upgraded to that. Unfortunately nothing has resolved. So i decided to try the MIUI EU stable 11.0.4 rom. But download speeds are the same across all roms.
It is strange, cos i don't see anyone having these issues.
Here-s a screenshot:
Interested in UK users experiences with getting network features working fully.
Does WiFi calling, volte , visual voicemail, 4G+ and 5G, GPay et al work for you?
What ROM? What carrier?
Did you have to disable carrier checks? Or did it work out the box?
Also non region specific stuff too I guess , android auto experience etc etc.
I'm on a contract with EE.
VOLTE, WiFi calling, 4G+, 5G and Google Pay all working without any issues straight out the box. I don't use Android auto so I can't comment on that I'm afraid. CN ROM currently on MIUI 12.5 stable.
Great stuff. Thanks for the reply.
Where did you buy from ?

I bought mine from TradingShenzhen here: https://tradingshenzhen.com/en/mi-1...omi-mi-11-ultra-12gb256gb-ultimate-of-android
I didn't have to pay any import tax or custom fees. You can also buy from Wondamobile which they say won't incur any import charges either: https://www.wondamobile.com/xiaomi-mi-11-ultra-5g-12gb-ram-256gb-dual-sim-unlocked.html
Yeah, I have used Wonda a few times. Going to go with TS this time to see how it goes.
Hopefully sell my old Note 20U soon.

I'm now in 12.5.2 EU rom, and on Vodafone UK.
Still no 4G+/CA. 5G does work but nPerf states it's 4G. VoLTE, VoWiFi, GPay all fine.
Be interested to know if anyone gets CA working on Vodafone UK with the Global or EEA rom. May have to wait to see what version is released in the UK.
Yip. I have ordered today from TS.
I have a EE work SIM, but use Sky personality. Will be interesting if all works with them as they are quite restrictive on device support.
I don't get 4G+ CA anywhere locally anyway, but bizarrely get 5G at the end of my harbour pier .
Will have to see if it's worth flashing global ROM next month after the UK release. Everything points to the CN being more than usable after tweaking though.
I was on Chinese stock, now global. Sky and EE work fine on both, I use them too.
Global obviously does have full Google services, not the mini pack that was on the Chinese but for some reason they use Google's phone, contacts and text app, so no native call recording. Global is still on original firmware where before flashing I had 12.5 which was a delight, hopefully 12.5 will hit the Global soon.
I will go Xiaomi EU ROM if and when a twrp is released or the fastboot bricking issue has been well resolved. I used EU version on my 10 ultra and it is a dam good ROM.
Brilliant.
@Sathelp
Does volte and WiFi calling work on SKY on CN ? ( Whilst I wait on bl unlock for Global )
Thanks

I did tested download speeds on chinese version of Mi 11 Ultra and guess what ? I am getting only 3.66 mb/s on GG network that runs on O2 architecture if im not mistaking .
Before i bought the phone i verified all the network bands and it should be compatible with all Uk carriers on 4 and 5G .
May it be some setting or something ? I tried 2 different speed test services .

Were you getting 4G+ before, and now not, maybe?
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

let them save a few bucks. Then they will fill the forum with questions and complaints. People like to discuss. However more activity is good for the forum.

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.
