Zenfone 7 Pro VoLTE & Wifi Calling support?

Hi all,

Does anyone know if we can enable VoLTE and Wifi calling on Metro by T-mobile?

I'm on Metro by T-mobile (which runs over the T-mobile network) and just received a text saying that I'll need to get VoLTE by July 1st -- otherwise I'll get kicked off the network.

I tried to look up how to enable VoLTE on Zenfone 7 Pro, but it seems like there is very little discussion on this. I saw a tweet in 2020 saying that T-mobile now supports VoLTE with Zenfone 7 Pro, so theoretically Metro by T-mobile should also support it...?

However, I couldn't find the toggle for it in the settings, as shown below.

I dug a bit into this and found that, in the SIM card setting, there's a "Dual SIM 4G + 4G" toggle, which says that "You have to subscribe to VoLTE call service to have voice call capability", and this took me to a post on XDA about rooting and enabling VoLTE.

Is there any way to enable VoLTE on the Zenfone 7 series without rooting? Mine is a newly bought phone and I don't want to root to break the warranty just yet 😕.

Does this simply mean that I will just need to contact my carrier to "subscribe" to the VoLTE call service? Has anyone dealt with this before?

Also, I was looking for Wifi calling and couldn't find any useful references for Zenfone 7 series. Any clue?

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.

    Don't have to many expectations. Asus is sort of focused ( at minimums) for the 8 series and ROG. Don't expect miracles for the 7/7 Pro . Will never come. And that's all. Asus doesn't have volumes for 7 series in many countries, they definitely will not pay licenses/provisioning for the operators. VoLTE and VoWiFi it is a lost dream, get used to it, unfortunately. Cheers!

    Cool beans. I've been searching for a solution on this one and crossed my fingers hoping that they've done something about it in the past 2 years, but I guess I'll have to make a switch after all.

    Thanks mate!
