Wi-Fi Calling on MIA1 for MI5X - Xiaomi Mi 5X Questions & Answers

Hi there, is there any way to activate/install something to activate carrier wi-fi calling on the MI5X running on the MIA1 Oreo rom available in this forum? I have a cottage with abysmal cell reception and would like to use the function to alleviate this... Thank you!

Advanced calling / VoLTE on XT109x?

Hello, I recently switched to T-Mobile from US Cellular and installed their SIM, all my other family members that's switched have VoLTE etc and I was wondering how I could get it? Does this device even support it?

Wifi calling

Hi - does any Moto G6 ROM support wifi calling VoLTE? - I searched for an answer here but couldn't find it.
Thanks
If you looked in the ROMs section, you'd see that there is only one ROM for the G6. And that one, if I'm correct, doesn't support Wi-Fi calling or VoLTE.

Wifi Call on MI 9

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.

WiFi Calling on US T-Mobile

I recently purchased the global version of the Mi 9T Pro and I am running stock MIUI Global 10.3.2 with US T-Mobile as my provider. OOTB the phone does not have a WiFi calling option. Since this is useful to me when traveling outside the US or in areas where I have WiFi but poor cell reception, I searched for a way to activate WiFi calling on this phone. I searched the XDA sub forum for the phone, but did not find any relevant threads (so apologies if this has been posted before). I did find a useful thread started by XDA member lightcao in the Xiaomi Mi 9 sub forum:
https://r.tapatalk.com/shareLink/topic?url=https%3A%2F%2Fforum%2Exda-developers%2Ecom%2Fshowthread%2Ephp%3Ft%3D3917887&share_tid=3917887&share_fid=3793&share_type=t&link_source=app
Based on the suggestions in this thread and other information, I did the following:
1. Ensured that my T-Mobile account had an e911 address listed.
2. Enabled WiFi calling option using the dialer code provided in the thread and activated WiFi calling under the sim card settings (new option appeared).
3. Updated the T-Mobile APN with the APN types as suggested. At this point WiFi calling worked, but only in airplane mode with WiFi enabled. This was because after enabling WiFi calling, the Network Preferences defaulted to WiFi Only with no apparent option to change it (grayed out).
4. Installed QuickShortcutMaker (sika524) from the Play Store. With this app I could access the Network Preferences setting and change it to WiFi Preferred. Although the grayed out setting in the phone is still showing WiFi Only, phone is now working based on WiFi Preferred and I can see the WiFi calling icon in my notification bar whenever I have a WiFi connection.
Although this is specific to US T-Mobile, in the referenced thread people with other providers and in other countries suggest it is working for them as well, as long as the provider supports WiFi calling. Hope this helps others interested in WiFi calling on their Xiaomi Mi 9T Pro.
I used the same method a while ago in mi9t pro to enable wifi calling on O2 uk network but i didnt need to do all the other stuff i just entred the dialer codes and it started working. I think this is the case with most miui based roms because it was the same with my Mi6.

Vowifi working?

Guys any custom rom with vowifi working in India?
Airtel voWifi not supported
I am also looking for the same. I live in Mumbai and there's ZERO network for Airtel (vodafone, MTNL, Jio get good reception). I don't want to switch provider again as I did it some time ago. I have a decent wifi connection and the news of wi fi calling made me relax however I was surprised to see that Airtel doesn't support Moto G5 S Plus. Tried various things but nothing worked when I finally realised that this phone doesn't support wi fi calling. If there is any custom ROM that supports wi fi calling, please do let us know as the network issue has literally screwed me. No calls at home. Thanks guys.
There is a workaround - if a carrier supports it - is called call forwarding.
Jio also not supporting VoWifi.
Looking forward for a solution.
