Do any of these let me call anybody's (ie, non-subscribers with no accounts and with no internet connection) phone for free in the US?
What I'm trying to do is dump the VZW network when I can't get a signal, and use my cell phone exactly like I would any other phone as long as I have my wifi up at home. If somebody I want to talk to has to subscribe to some service, that would be useless for me.
Is this possible?
