So my contract with Verizon is up and I have been drooling over the Thunderbolt now for a few months. We currently have a family share plan with the $10 unlimited text plan on two lines. I would like to ditch that when I renew my contract to soften the blow of adding data to both lines (we both have dumb phones at the moment). My question is are the text messaging apps a suitable replacement for the text messaging on the plan? What are the pros and cons? I would still like to be able to send and receive text messages from friends and family that don't yet have smartphones. I would also like the ability to send and receive picture messages as well to those same people. Is this something I will be able to do with an app or apps, or am I asking too much? Thanks!
