I have no idea if that's true after using this service for about 5 months now. And I doubt I'll ever find out, since I almost always use Wifi anyway. All I know is that I pay at lot less, have fewer dropped calls, stopped worrying about how many text messages I use, and I haven't been charged extra for going over on phone minutes like in the past.
