    I posted this in another thread but I didn't get any responses. I have a T-Mobile 9900. If I upgrade to a firmware from another carrier will I loose my wifi calling?

    I'm, also on another carriers OS, and my wifi calling is fine. Still not as good as UMA used to be though...

    On the TMo OS I find wifi calling very very poor even with a strong signal.

    Thanks for the replies! I downloaded the software from Cincinnati Bell (7.1.0.2108), has anyone used this version yet and is it stable?
