I have an issue with every build I've tried of MIUI 8 (Stable versions), but not with the developer versions of MIUI 9.
The phone will not connect to UMTS/3G networks with either sim. LTE works fine, and there's no GSM where I live so I can't test that.
It will connect for a moment when first booting up the phone, then immediately disconnect and stay disconnected. It can't find 3G networks when searching either.
Again, this doesn't happen on MIUI 9 builds, but I figure this big of a bug, they would never release it as stable. Can anyone else let me know if they've had this problem?
Hello, I`m having same issue, here in this way. In town there are many repeaters. Here is no problem, in germany many 4G-Networks are working in band 20 (800 mhz). In areas, where no 4G/lte is possible, the mi mix2 (china stable miui8 and china dev miui9) the mix2 can not connect to 3G/UMTS. A smartphone Redmi note 4 with this SIMCard connects to 3G/UMTS and gets connection data to HSDPA+. The mi mix icon diasappears and there is a "emergency" Icon. Then the mi mix2 connect only to GSM and after 1-2 minutes get Data to EDGE. But at this place it is possible to connect to 3G. I rebooted the device many times, changes sim to other slot. Tried China dev and stable. Last test with XIAOMI.EU and EPICROM for MIX2 are sad. Same issue
Many MIX2-User have this effect. I have this effect on Sim-Cards from provider Telefonica/O2. I have tried 3 Sim-cards from provider O2. No 3G - Connect.
In germanys-forums the is a hint to define "force 3G-Connects". Some user writes, that they do not have this effect with this definition.
Does have XIAOMI a 3G-Bug with new MIMIX2??

If you're on MIUI 9 beta, you already have the radio I'm talking about.

okay, it doenst fixed that
The default Setting for this SIM is: LTE/TD-SCDMA/WCDMA... this is almost wrong, because we havent TD-SCDMA in Germany, i ve switched to LTE/UMTS RPL ...this seems to work better with my o2 card.
Sometimes the connection breaks down from LTE or LTE+ to H+ ...but after the break down, i have no data connection. If i activate flight mode and re enable data, i also get H+ but for now with data connecting. This is very frustrating
Also that my Settings to LTE/UMTS are removed after a reboot or i switch to the second sim. Any suggestions to fix it permanent to LTE/UMTS ?
Did anyone tried MI MIX 2 Global - Version?´ Bug exists still there?
I am on 9.1
I set it on LTE/TD-SCDMA/GSM. I live in Germany too and have a O2 card.
GSM is slower than UMTS cause it's older. But it works without problems.
Now I trying with LTE/TD-SCDMA/UMTS. I have to say that I have some problems too.

we dont have TD-SCDMA in Germany so, this setting is false... TD-SCDMA is a chinese or asian network standard

yep, this seems to works best and also breaks down to gsm if there is no other network available... but...
sim 1 + data card : o2
sim 2 as voice card: D1
if i make a call with sim 1 / D1 my first sim as data sim loose the data connection, even it is connected to a lte network...strange thing today i had a conf call over sim2 for about 4 hours, while this time i didnt recieve any mail or whatsapp.
but if i set sim 2 / D1 as data card and make a voice call, this card wont loose data....strange, maybe a o2 issue?
edit: made a test with D1 as data and if make a call with the o2 card, also d1 loose data instant
I have a new (2.nd) MI MIX 2. And: I have the same Problem. O2 is switching vom GSM/EDGE to UMTS an gets no Connect. Then only "EMRGENCY CALLs". And then GSM again. o2 is provider. roaming is on.
With second SIM (Vodafone) there is no problem. Is there a fix for that problem? One member wrote there is a new "radio". Where to find it?
Same SIM (o2) in a REDMI NOTE 4 (LTE Band 20 800 MHZ) is "ok". It is an MI MIX 2 - Problem!
I have the MIUI 9 Global.
MI MIX2 with O2 and no LTE and no 3G/UMTS??? Joke?

change network to LTE/UMTS PRL ...then it should work better PRL = prefered roaming list; go to settings -> about phone -> tap several times on the info about internal storage -> the network app will appear, now you can change network settings... until next boot, then you have to set it again
maybe mix 2 has a problem with national roaming?! cause o2 uses national roaming -> their own network and the network from e-plus
Yes, the MIX 2 does have issues with switching to anything other than LTE. Even when it says it switched to H or H+ there is actually no reception at all and it takes a few minutes for it to recover. Really annoying, hopefully the engineers fix this issue as soon as possible. Pretty inexcusable bug for such a device.
Hello, Switching to " LTE/UMTS PRL" has the effect, only UMTS/3G-Connections are possible. No LTE/4G. Provider: German O2.
XIAOMI might have to fix this bug.
Q: Has anyone took a Message to [email protected] ?? http://en.miui.com/forum.php?mod=bugfeedback&fid=5&page=1

LTE/UMTS PRL fixed that for me totaly ... i dont had any issues since them! I am also getting LTE and LTE-A with o2 and i am travelling a lot due to my job in germany.
i think its also problem with o2 and national roaming. if you search for this problem in google, you will find the same issue reports from other devices within in the o2 network. I did never had the same problems with my other D1 card in the same device.
LTE/UMTS does not work for me.
Since yesterday I use LTE/TD-SCDMA/UMTS and it works fine.
Provider: O2 Germany
It looks like 3G/HSPA doesn't work when roaming (possibly local roaming too). LTE works fine. In the UK I can get internet all the time regardless of connection type. I travelled abroad and only LTE worked using my UK SIM. This also happens on AOSP based ROMs since I'm using Resurrection Remix and still experienced the issue.

Yes, this is clearly a firmware-level issue. They need to fix their modem.
Hi, I have Redmi Note 5 Pro 6/64 china version flashed to global version. I saw on youtube that this phone is capable of VoLTE, native Video Call and VoWifi. My network provider is also capable of VoLTE and VoWifi. I was wondering what MIUI version supports video calling from native dialer app, I'm currently on MIUI 11.0.5 and the video call icon is not appearing in the dialer app, and lastly I am not getting the update for MIUI version 12.
I think it depends on the carrier, I am Using Jio (India) and getting native Video Call but not getting VoWifi
really weird cause Video call is supported by the carrier but native video dialer not appearing, i got me a Redmi Note 9 Pro 5G / Mi 10i and still it does not show, although I'm using china rom this time
Hi all,
yesterday I wanted to activate my ESim on my HW3 Pro. All fine. Got coverage. BUT: unable to use the coverage as calls (in and out) are not supported by Swisscom. Calling them I learned that Huawei is banned from Swisscoms network due to the dispute between Google and Huawei it seems.. incredible.. Any other operators in Europe act the same??
