Is it possible to use my wireless broadband as a cell phone? or a phone that plugs into my laptop? I need to reduce my bill- don't use my cell much at all- but the laptop all the time.
like you mean doing Skype Calling over Sprint's network or some sort of VoIP service? well first of all does Sprint filter out that kind of traffic? and also if they don't would that make it easier for the OP to hit his 5GB cap?
