Not True
T-Mobie has offered WiFi Calling since 2007. I had it on a flip phone!

It's not just Phonescoop that keeps getting it wrong as far as when T-Mobile began offering Wi-Fi calling. Almost every article on other tech sites that brings this up says T-Mobile recently began offering Wi-Fi calling - wrong.
And , strangely , no correction from T-Mobile or their very vocal CEO.

You want to know why?
Because they know they are in fault, they was supposed to request this same waiver to the FCC before start to offering WiFi-calling.
Sprint it's on the same boat

That's probably in part because in 2007, it utilized a technology called UMA (Unlicensed Mobile Access) and was available primarily on Blackberries and some Nokia and Moto phones at launch. At a high level, it functioned like Wifi calling, but was somewhat different on a technical level. Ironically, UMA supported handoff to the Mobile network - the current implementation of Wifi Calling does not (rather, it is not implemented by T-Mobile, although the specification allows for it).

T-Mobile does handoff to the mobile network from wifi. To the LTE mobile network that is.

The current method of WiFi calling at T-Mobile is different then it was before. I've heard stories its better, but at the very least it only became an advertised feature of T-Mobile recently. Its now offered with all smart phones, wifi calls can hand off to VoLTE, and T-Mobile will give customers WiFi routers if they need one.

True, but it was for a different reason, T-Mobile did it because of lack of service in many areas. Which has significantly improved, probably to the point it's not needed for the most part. Still it was nice to have it outside the country and there was open wifi.
AT&T and VZW did it mainly because it was an iPhone feature that they wanted to impliment.
