Why isn't T-Mobile mentioned here? We use UMA - calls over wi-fi for $9.99 a month for all phones on a family plan, 24x7 on T-Mobile without eating into are monthly allotment of minutes. UMA is a good thing!
I'm having trouble understanding why you have to pay T-mobile to use the internet connection that you already pay for to place calls. How is this costing them any money?
