VOLTE should work out of the box.

4G is technically LTE. The Xiaomi firmware doesn't seem to have an LTE icon, at least not that I have seen. 4G and 4G+ are LTE and LTE-A.

thanks for the info

After the *#*#86583#*#, try going into Mobile & Networks, and select your SIM card. There should be a VoLTE enabled option now. This option didn't show up for me until I did that and then I had to turn it on.
There's now a tiny VoLTE icon in the notification bar and when I'm on a call, it stays there.

Try code *#*#869434*#*# to disable VoWIFI check. And check if it working on T-Mobile.
I don't have Tmobile to check it.

No, VoWifi doesn't work on t mobile

What ROM's have people tried for WiFi Calling? Does the OP refer to T-Mobile in the UK/EU or USA? The Global Stable seems to have some less features compared to the Chinese Stable. I had Advanced Messaging working in the default text app when I was on Chinese Stable by doing nothing but it does not seem to work on the Global Stable.

got volte working on tmobile US just not wifi calling but its fine

Which ROM is your device using? I really want to flash my green one back to the Chinese Stable. Global Stable just isn't as good in my opinion.

Eu global the lastest one 10.2.2.0

Ever find a solution to this? I am on MIUI Global 10.3 (Stable) and am able to turn off Mobile data( T Mobile is my carrier in U.S.) and with my WiFi on the device i can still make and receive phone calls. In this configuration i obviously still see my WiFi symbol in the Notification bar as well as the VoLTE symbol. Don't know if this will help you at all, but it is some stuff i have noticed recently when i was trying to figure out why T-Mobile apps dont work on my Mi Mix 3.
With WiFi turned off and Mobile Data turned on i am able to make phone calls(obviously) with VoLTE and am able to see the LTE+ symbol in the Notification bar as well.
If i go to About Phone --> Tap "Internal Storage" 4 time(brings you to the Testing Menu) and looking into the Phone Info i see the following...
Set Preferred Network Type: LTE/TD-SCDMA/UMTS
Mobile Radio Power: On
VoLTE Provisioned: Off
Video Calling Provisioned: Off
WiFi Calling Provisioned: Off
EAB/Presence Provisioned: Off
When i bring this menu up on my previous phone(LG G7 ThinQ) i see that the Preferred Network type was different...so i changed my Mi Mix 3 just to match to see how it would change
My LG G7(without a SIM inserted) shows the following
Set Preferred Network Type: LTE/UMTS auto (PRL)
Mobile Radio Power: On
VoLTE Provisioned: On
Video Calling Provisioned: On
WiFi Calling Provisioned: On
EAB/Presence Provisioned: Off
Changing the network type on my Mi Mix 3 didnt do much, however when i changed it LTE/CDMA/UMTS auto(PRL) the VoLTE Provisioned and Video Calling Provisioned both switched to "On".
I dont quite understand this so for the most part i have just left it to match my LG's setting since i can change the network type back to LTE/UMTS auto(PRL) after and the settings stay set to "On"
Made a few test phone calls after with WiFi on and off, everything seems to work just fine regardless of what the phone displays.

Put the device in airplane mode, then turn on WiFi. Can you make calls? I can't! Turning on WiFi and enabling WiFi Calling doesn't mean the calls are going over WiFi. Especially if you are still seeing VoLTE or any time of mobile network connection.
Edit: Go down to the very bottom, hit more, hit IMS status, and see what it says.

Yeah I looked at the IMIS before, voice over wifi has always(I assume) said not unavailable

No access to the IMS settimgs is more than likely why we can't get it working. We cam't see the settings to even compare them to what they should be.

I am on MIUI Global 10.3 (Stable) / Chinese Device / T-Mobile Germany.
VoWiFi as well as VoLTE are working on my device, however you need root access to enable the VoWiFi profile.
Once it is working you will see the WiFi calling icon in the status bar.
I was following this guide to enable WiFi calling on the Mi Mix 3:
https://forum.xda-developers.com/poco-f1/how-to/guide-activate-vowifi-wlan-call-t3871263
I don't know if the mentioned profile will work in other countries as well but maybe someone with more insight can shed some light into this.
I remember that VoLTE was working out of the box, you just have to disable the carrier check with the USSD code to make it available in settings.
VoWiFi can be enabled via USSD code as well, however even after changing the setting to enabled and preferred WiFi calling it does not register without the profile change.
VoLTE: *#*#86583#*#*
VoWiFi: *#*#869434#*#*
I had to redo the profile change after each upgrade with TWRP, since the firmware partitions get updated as well.
I hope this will help. :fingers-crossed:

I have Mix 3 with U.S T-Mobile service. After disabling the VoWiFi check with *#*#869434#*#*, the option for WiFi calling check box appears under the T-Mobile SIM section, but WiFi calling is not working when tested under airplane mode with WiFi enabled.

Vowifi works fine on MTS (Russia). All you need:
1. Activate vowifi service from the operator
2. Disable service check by command: *#*#869434#*#*
3. Create folder into: /system_root/system/priv-app/MBNLoader
4. Copy into this folder APK: MBNLoader.apk (View attachment MBNLoader.apk
5. Give right privileges: -rw-r--r--
6. Reboot phone
7. Install from play market QuickshortcutMaker: https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut
8. Open it and go to tab apps
9. Find Modem Config
10. Open it (tap) and you will see a lot of MCFG Modem configs.
11. Try one by one to start vowifi working
12. Enjoy!

volte and 4g icons in status bar

Hello guys,
Now from what i know about this phone it is dual 4G and i have it enabled in developer options.
I also have volte service activated from operators on both sims, but only one sim displays the volte option and 4G icon in status bar. I have tried switching the sims and then volte/4G icon appears only for sim 2.
According to Network cell info software i have 4G/4G+ on both sims and Data Network is lte for both, so in theory both sims have volte and 4G enabled, but it displays only for one operator.
My question here is if anyone has volte/4G icons for both sims in status bar and if you can share a snip as proof.
Thanks.

Only works in Sim 2 for me, see attached screenshot.

At least you have 4G for both. Mine only shows 4G on the active data sim only.
Would appreciate if anyone posts a snip with both 4G/volte for both sims. i have a ticket opened at Huawei and want to give them an example that on how it should display.

I will show you tomorrow with 2 simms from Orange and Digi Romania.
Take in consideration that here Vodafone has VoLTE without showing a VoLTE icon on any phone. On Vodafone I can not switch off the VoLTE because is no slider/option on network menu. They activate VoLTE from their server so if I want to deactivate it I have to call them. You can verify if you are in the same situation as follow:
- keep data mobile on this sim (no WiFi).
- Network 4G
- initiate a phone call
If remains in 4G means you have VoLte activated but no icon (carrier option). If commute in 3G means you don't have VoLte activated
I will change the Vodafone Sim with Digi one to see 2 icons.
LE: Orange Romania + Digi Romania

Hi,
Ok, I can understand the volte icon is carrier dependent on Vodafone, but what about the 4G icon? For me it only shows 4G icon on the sim where I have data active only. Check attached pics.
And yes, I know about the test you mentioned and yes, it stays as 4G during a call. I know I have the option active(since for vowifi I get icons on both Orange and Vodafone) and I checked with Network Cell Info program and it says Voice Network is lte on both sims.

You have to use Tweaker for Huawei.
View attachment 5015499View attachment 5015501
Apply and restart.
LE You can ask also here: https://forum.softpedia.com/topic/1148606-huawei-mate-30mate-30-pro/

Thx for the tweak tip.
@Sathelp : did you use the tweaker to get the 4G icons on both sims? Or maybe you see both because the phone is 5G model..

No, I hacked to get the VoLTE working (search for my thread) but the 4g is standard, sim one is Sky (O2) and sim 2 is EE (UK) . I have reasonable signal levels.

And with that app what that you get?
Can I make VoLTE calls or enable the VoLTE icon in the Mate 30 Pro's internal menu?

Follow the discution from the beginning. In this case, you can enable the network icon on the second Sim.

To be honest it asks me for root also to enable 4G icon on second sim. No idea why it works for you.

It asks because some functions need that. Not this one. It is better to try it. It is easy to do it.

I found the setting to display the 4G icon on both sims with SetEdit:
isShowNetworkType to be changed to 1

Sure. The same thing, different app. No root needed?

No 5g icon

I have a strange issue, the phone is connected to 5g network but the icon is still 4g, can anyone confirm this? I am not sure if is a theme issue or something else

Looks like your network doesn't send UpperLayerIndicator so that is reason why 5G icon doesn't appear to status bar. Maybe 5G is not officially opened?

I do have the same issue and I was able to contact level-3 support of my operator. Can you provide more information about that? @lovers74 : where is this screen coming from? @olkitu : Thanks for this information "UpperLayerIndicator " seems to be the keyword!

I used an app called Quickshortcutmaker, and searched for 5g.

It is officially opened, and working correctly and on other devices such as Huawei or Samsung I can see the icon.

UpperLayerIndicator is in SIB2 signaling message to tell UE (example phone) this LTE tower have 5G support. Otherwise UE shows 4G icon.
Some UE like Huawei and Samsung shows 5G icon when connected to NR even network doesn't have UpperLayerIndicator in SIB2.
And most of devices show 5G icon without 5G NR... "Fake 5G"

It's N78 5G? On a S20 Ultra you see 5G but it's greyed out, because it's only 5G in downlink.

Samsung shows 5G when network send UpperLayerIndicator message and then change 5G icon color when connected to 5G layer. You can use example CellMapper app to see if 5G State Connected or not.
n78 is not only downlink, can't be uplink too. That depends network configuration.

Showing 4g instead of LTE

Hi. I'm from Poland where we have LTE standard, but my phone is ignoring that and still showing 4g icon. Is there any solution to change? I won't to do factory reset.
And one more thing... Is there a LTE +/4g+ on Pixel 4a ? My other phone show IT but Pixel never do that. Thanks

4G is LTE
My phone says 4G too. An older phone would be more explicit about the technology (eg. 4, H, H+) but I guess Google or Android doesn't do that anymore.
Maybe this helps?
Network Type Indicator - Apps on Google Play
Status bar indicator of the type of mobile network in use (e.g. 2G, 3G, 4G, ...)
play.google.com

Hi! If you are rooted, you can change it. There could be xml file:
Code:
/data_mirror/data_de/null/0/com.android.phone/files/carrierconfig-com.google.android.carrier-XXX.xml
where XXX is some number. Inside this file should be an entry
Code:
<boolean name="show_4g_for_lte_data_icon_bool" value="true" />
change its value to "false" and restart...

Thanks for answers.
I know that 4g is my LTE. I don't know why showing on my region 4g icon. After reset conection settings, it shows LTE for 1 sec and change.
I'm not rooted i was played with it on other phones but Pixel is great as it is.
Do you know how about with LTE+/advanced on this device?

5G on LG V50

Hello,
I have a LG V50 5G - version LM-V500EM, Android 11, SW version V30b-EEA-XX. I guess it's the Korean version - it has on the back the 5G logo and the pins for the second display at the bottom.
Also, I have a 5G subscription on Orange carrier, in Romania.
So I have a few questions about the LG V50 :
1. Should there be a 5G option in the Settings menu -> Internet and network -> Mobile network ? I'm asking this because on different phones, even LG ones, there is a option for 5G. An example is LG Velvet 5G, which has 5G auto option in the Mobile network menu. Or because the phone (LG V50 5G) supports only the 5G NR N78 band, there is no option. In contrast, because the LG Velvet supports multiple 5G bands, it has the 5G option ?
2. How do I know when the phone connects to a 5G mobile network ? Or to any type of mobile network ? I only see the mobile signal strength in the top right corner, but no additional information. On other type of phones, even LG ones, you see 5G, 4G, 3G, VoLTE etc. Is there a way to enable, to be shown like this ? I know I can see the type of connection if I go to settings, but I wanna see it on the main screen.
3. This is related to the 2nd question - When the phone connects to a 5G network, does the logo on the back do something ? Like intermittent flash with red color ? I see that when I receive a notification, the 5G logo flashes in blue color
I attached some pictures, to better understand what I'm saying. Unfortunately, the menu is in Romanian and so are the pictures but you get the point.

Hi, in Poland on my V500N I have like this:

Thanks for the reply, guess there is a SW problem with mine.
Still, I managed to activate the 5G using the secret menu code *#546368#*500# and the following path :
Field Test -> Modem Settings -> RAT Selection and selected from there the option that contains 5G NSA. The only dilemma was that there were 2 options that contained the naming and surprisingly both of them worked for me (I observed no difference between them).
By the way, so you have the 5G logo on the back ? If yes, when it's connected to a 5G network, does it stay lighted in red color ?

I have this logo, but my operator does not support 5G for now.
I am in Orange, but in the Orange sub-brand for young people - NJU and so far there is no 5G for this brand. Besides, I don't care too much.
If the phone connects to 5G - you will have the sign 5G instead of LTE on top bar of screen.
As far as I know, the logo on the back will have some color - red or orange ...

I have the 5G sign in the top right corner but I also wanted to see it in red on the back, as in the launch video. I thought that it's somewhat "fake positive" if it doesn't also light red when the 5G appears on the screen.
Thanks so much for the response and have a nice day !
