Default UMA on an unlocked ATT 9700 on Tmo's network

Please Login to Remove!

I have an ATT 9700 that I'm going to unlock and use on Tmobile's network. I want to use the UMA wifi calling on this phone with a Tmobile SIM card present.

My Tmobile business rep told me this was not possible but if I update the software on the phone, I'm hoping it will work.

Anyone know what I need to do to make UMA wifi calling work on an ATT 9700 after its unlocked and connected on Tmo's network?

Have a read through this. Not sure if it applies to the 9700 but should at least point you in the right direction.

Note that you will only have EDGE data speeds and not 3G...
