Hi,

anyone managed to get Wifi Calling and VoLTE to work on Singtel?

I had and iPhone 7+ and all are working.

However, using the same SIM card, putting into my Mi Mix 2, all I get is 4G.

There is no enable VoLTE setting inside SIM Card settings.
Changing to another locale like Malaysia will make the VoLTE setting appear, but it is greyed out.
"VoLTE calls aren't supported for the modile data SIM card."

That was on stable 8.5.1 international ROM.

On China stable ROM 8.5.5, there is no way to change local, and thus the VoLTE settings does not appear at all.

Now on beta 7.10.12, VoLTE settings appear, but still greyed out.

I have tried adding ima into the APN type under all scenarios, and rebooted phone, but the results mentioned above are consistent.



And for WiFI calling... I am totally lost.

Any kind soul can help?

solved VoLTE on stable 8.5.1 on Mix 2

change region to Malaysia

key in *#*#86583#*#*


to check if VoLTE is supported in your network, key in *#*#4636#*#* and go into phone information.
If it shows voice network as VoLTE, just do the above will do.

even on Singtel, I get 4G+ here and there, it is not for sure have 100% of the time.
but even on 4G+, the speed is no where as fast as advertised, it is almost the same speed as a normal 4G speed.

if your carrier supports them, xiaomi should not have a problem with it.
Just need to change the region to get it to work.
