Does xperia e dual support wifi calling?

[kha]

Hi have Tmobile and would like to know if the xperia e dual supports wifi calling. From the tmobile website, the xperia z supports this feature. Although the Z is a much more expensive model, I'm wondering if this feature is shared with the xperia e. Has anyone been able to use this feature, and how did you do so?

Thanks!

Responding to my question, the answer is no, unless i came from a tmobile store. 

thanks.
