========================================
Hello,

I got a ROG Phone 5s and it works great! However I'm not seeing any options for WiFi calling in the settings. I have the latest firmware, and my carrier supports WiFi calling, as I have used it on several past devices. Will this be added in an update or is there something I can do to fix it?
Thanks

The only ASUS smartphone validated with T-Mobile is the Nexus for this function, as long as ASUS does not bother to include WIFI calls and send them to carriers or vice versa, as long as carriers both consider not ASUS as a big enough manufacturer to include ASUS devices (if ASUS has done its share of work in its smartphone?) it won't work.
