Possible solution for Wi-Fi calling on T-Mobile / there is an android TMo Wi-Fi calling app
I've just about tried everything I can to get wi-fi calling to work.
Although the TMo app on Blackberry App world says it supports the Z30, I cannot get it to work. I also tried to email the developer. I cannot figure out how to do that. TMo said I wasn't allowed to email their employees.
Here is the link to the Blackberry World TMo app

However, I found an Android TMo wi-fil calling app. I can't figure out how to load it. I've been using Snap. But when I open it. It goes directly to Google Play. I'm sure there are lots of people better at side loading than me. Would another Z30 user with a TMo sim card see if they can get the Android app to work and then write back?
