Explain T-Mobile's wifi texting?

[zackmack7]

To my understanding, T-Mobile phones can utilize wireless texting along with the wireless calling. How does this work, and can MMS be sent over wi-fi in addition to regular SMS?

Right now, I have wireless calling disabled on my T-mobile GS6. Does this disable the ability for wireless texting as well?

Just curious to how this all works. Thanks!

Yes you must have wifi calling enabled to use that feature. When wifi calling is on and you're on wifi.. Calls, text, and even MMS messages are routed through your wifi instead of cellular.
