Hi,
I have 2 SIM cards in the Mi A2 (private / business). After work I deactivate the sim 2. Now it is so that the speakerphone in the car radio (Mercedes) after a change from LTE to H or E indicates no signal.
The A2 is normally connected to the radio but the reception indicator on the radio shows no reception and does not let me call.
However, if both sim cards are active it works.
Oneplus had the same problem with the 6er at the beginning (but was then fixed).
Has anyone else this problem?
Kind regards, Sascha
Is the Mi A2 connected to the car by rSAP protocol (with disabling the A2's own gsm-connection) or is the Handsfree protocol used ? I'm asking because I plan to buy the A2, need the rSAP-Protocol, but no one could tell me wether this protocol is implemented in the Mi A2's Stock Rom.
No solution yet but I think it has someting to do with the rSAP protocol.

Hi,
I open a thread here because I have a really strange problem.
I currently have a Xiaomi Mi5 (MIUI 9 Global 8.3.8 | Béta) and a mobile plan with a French provider. VoLTE is enabled for the provider side and I have the VoLTE icon at the top of my screen after reboting my phone. When I call a French mobile phone (regardless the provider), the call is successfull in VoLTE (I am able to surf during calling). Unfortunately, when I try to call a French landline number (no matters which is the provider), the call is not connected and I obtain the message "Call ended". When disabling the VoLTE, my phone is in LTE, switch in 3G when calling and everything works well.
I have a friend who has a Mi Mix 2 with the same provider than me and VoLTE works well for all numbers he tries to call. I tried to put his SIM card in my phone and the same issue appears. It's my phone fault.
Do you have an idea of what could happen?
Thanks in advance
Hi,
I made a full wipe and I flashed the latest stable ROM via fastboot (MIUI Global 9.2 | Stable 9.22.1.0 (NAAMIEK)) and I have still the same issue.
Does anybody has an idea?
Thanks
As far as I know, both called and receiver must have VoLTE enabled. Your phone's behavior seems quite normal to me...
By the way, what happens if you put your sim in his phone?

I'm currently using the MIX 2S with MIUI 10 in combination with O2 / Eplus. The provider does defiantly support the WIFI Call, but MIX 2S does not support it.
What's about MI 9. Does it support in combination with the actual MIUI ROM the WIFI Calls?
Yes, using it with Telekom Germany (D1).
Just enter *#*#869434#*#* in dialer and enable it in phone settings.
Thank you. It's the same approach for Mix 2s, but it' not working with O2/Eplus even if the provider does support the feature. So I assume Wifi-Call wil also not work on Mi 9 with O2/Eplus.
wifi calls working great with SFR (france)
WiFi-Calls on Mix 2S and O2/Eplus are working also great with LineageOS 16.0 too, which is available for MIx 2s. But it's not working with MIUI.
I'm sure it is the same situation for MI9 WiFi Calling. Or have somebody managed to enable MI9 (MIUI) Wifi-Calling with O2/Eplus?
Wifi calling on o2 Germany works after you enter *#*#869434#*#* in the dialer and then check sim settings and enable there. However it is quite spotty, sometimes it does not register after connecting to WiFi or loses the connection after some time, but it definitely works, I performed several calls in flight mode and only WiFi enabled.
Hello!
I hope someone can help me with this "little" problem that I'm experimenting with my Xiaomi mi 9T Pro running MIUI Global 10.3.3.0 (Stock) I checked everything before buying and the phone is fully compatible with my carrier (I'm from Venezuela), however, I noticed that when the phone is on 4G it switches to 3G/H/H+ in order to make/receive calls (which is pretty normal since my carrier does not support VoLTE). The problem comes when there is an incoming call, it should switch automatically to 3G/H/H+ BUT it does not happen all the time, in fact, I can say that it only happens 25% of the time when I was testing, of course, when it does not happen there is no way to receive the incoming call.
So far I tried:
- Forcing the phone to stay on 3G (everything works great)
- Testing the different network options (it switches from 4G to 3G but not always and it should)
- Switching from SIM slot 1 to slot 2
- At the moment the preferred network type LTE/TD-SCDMA/UMTS
Could it be a software issue? or could it be related to my carrier? I haven't tried using a SIM card from another carrier.
After all, I bought a PHONE that does not behave like an actual phone all the time, so, I hope someone can help me with this.
Thanks in advance.
Note: I noticed that I might be posted on the wrong section, I'm sorry for that.

Thank you, I almost thought I was the only one.
I bought my Xiaomi mi 9T Pro running MIUI Global 10.3.3.0 (Stock) a week ago and I have the same symptoms like you.
Im on A1 Network in Austria running default network settings and I realized after hours I couldn't make calls (and obviously did't receive any).
This is the first phone I had this network problems, and I am on A1 network for 20 years with different phones....
I hope someone can share some light why this happens and what are the best settings for European (Austrian) A1 network.
Trying to switch to LTE/UMTS, but that setting is always reset to the default above after reboot.
As its also my work phone it would be very bad not recognizing for hours that I'm not reachable...
Thank you !
A1 supports VoLTE, try to enable it on your phone, I have no issues running a dual SIM config with A1 and 3 .....

Hi! It feels better knowing that I'm not alone.
The fact is that I can actually make calls (it take from 3 to 5 seconds switching from 4G to 3G/H), the problem comes when there is an incoming call, sometimes it works (it switches to 3G/H and when the call is ended, it switches back to 4G) but most it does not. I just tried LTE/UMTS and it does work but not for long, I can see that it happens and sometimes it does not. I found a "solution" which involves forcing to 3G/H but it's not the point, there should be a real solution. At this moment, I haven't found a correct network configuration, all the ones that I've tried just have worked for me for some time, and then the problem is back without even rebooting the phone. Could it be caused by a faulty SIM or it's just a network/carrier issue? I don't want to think that it's a hardware issue.

Whats your ROM Version ?
I alreaddy tried to enable VoLTE, I can switch it on and the VoLTE Symbol appears.
The problem is - I have no caller ID. I don't even see the phone number when someone calls me ("unbekannter Anrufer" - "unknown caller")
That's not conveniant, so as soon as I switched OFF VoLTE caller recognition was enabled again.
Is VoWIFI working at you with A1 ? I can enable it but I don't get the symbot at home in my WIFI network.
So for now I see two options:
- the correct (stable) network configuration for Austria that persist in the phone configuration
- enabling VoLTE but with a solution for a working caller ID
I finally got found the solution
Problem is the notification settings.
This was somehow reset after the update to mui 11.
To fix the issue:
1. Go to settings
2. Click notification
3. Click the notification badges (3rd icon)
4. Find the "phone" icon
5. Enable the show notification
6. Exit to settings and test
Having same problem
Can someone help me I am from Malta and have Xiaomi mi9t pro and from last night stopped receiving calls and incoming . Tried with sim 1 and it worked but it happened again . I tried the notification settings but still the same problem .
I had trouble not receiving calls also...
After looking here, and also on YouTube, I started going through my phone again. I too was not getting my calls a lot, but I have only had my phone maybe 2 weeks, so there's not much on it yet. One thing I am always adding is themes. The theme feature is it's own pre installed app as I'm sure we've all seen. Different one's have been doing/blocking certain features at times on my phone. My husband's calls were being sent to voicemail, and some other important calls. I noticed the other day when I tried a new theme it locked me out of my phone with no preface to get back to the lock screen. I had to take a picture and select send to get back to the lock screen. Remembering this, I decided to go back to the original developer theme for the phone. My phone now rings. Original developer mode also controls the call feature, not just the theme, which I did not know or read until now. Going back to it I believe kind of reset my configuration. I would say give this a try for sure. Hope it helps someone else I love my phone and didn't want to lose it. FYI, I am on TMobile network in the USA.
Hi!
I have a very similar problem on a xiaomi redmi note 8t. I tried various settings, but failed. This is annoying because the phone is relatively new. I think it is a hardware problem.

I have the same issue here in same phone but on EU MIUI 12.0.3.0 .. with the same symptoms u described .. i suspected in sim card and i replaced it with a new one and the issue still there .. did u find a solution for this issue?
I'm not sure if this is the same issue as what's described by OP, but it's somewhat similar (not receiving calls). Sometimes my colleagues will call me on Whatsapp and state that they're unable to reach me via the cellular network. This is what fixed it for me:
Settings - SIM cards & mobile networks - Select your sim card - turn off 'use volte (use volte to improve the quality of voice calls)'

Hi ,
Since 4 Weeks im the owner of an Mi11 .
Unfortunately I have to say that I am very disappointed with this Device .
My Problems are :
- very poor WLAN Receive Power ( maybe the Antenna ) , i change my AVM Fritzbox against an new one , but still the same Problems . Mesh Thettering / Switching dont work perfectely . With my Company Phone , an Iphone 11 the Mesh Roaming works like charm and it receives in my kitchen 560 MB/s with the 5GHz WLAN.
My Mi11 drops down in Kitchen, wich is 3 meters away from the Fritzbox to 10MB/s or it loose the Connection completely . The Mesh roaming dont work too.
Till the Mi11 change to my Repeater the Bandwith goes down to 5 MB/s the maybe it switches to the Repeater who can deliver again 500 MB/s .
- Poor Mobile Network Power . I loose the Connection on Calls on Places where i can take Calls with my old Huawei Phone.
Am I the only one with these problems or do others feel the same way?
Thanks
Michael
I don't have such WiFi issues
and regarding mobile data, are you using the same operator and SIM card as in huawei?
Ok , Hmm . I use the same SIM as under the Huawei Handy .
for wifi -> i have the same, disabling WPA3 helped a little on my fritzbox but not in total
mobile --> the same, i have my company pixel 5 next to my mi 11, both have deutsche telekom sim, pixel is having a much better signal and also gets higher download speeds
Clear system cache, network reset, clear sim card tool kit data, check Access Point Names, replace sim card.
Also, try to adjust the incoming signal throught the hidden menu of which your sim approves.
I dont have these problems with my mi 11.
I have my Mi11, since the beginning of last month, and i must say i never experienced bad wifi/cellular connection. So i suggest you make a network/factory reset..

I think Xiaomi's European models have problems in all areas that the Chinese models don't. My CN model has fantastic WiFi values with both the original and the Xiaomi.exiaomi.eu ROM. I also have the Fritzbox as a router.
