I thought that too but then I realized if I can't talk (poor signal, consistently dropped calls) then I certainly can't "talk and data at the same time," either.
I live in SoCal havn't had call drops in 2+ years. Signal never realy get under 2bar's. With the exceptions of being underground or big buildings etc...
I just wish they had more LTW towers.
They said they supported LA but thats only partly right. They shouldn't list LA unless it was all supported. or add an * or something then list the area's it is.
I would of totally went with Verizon if I knew this.
