Switched from ATT/iphone (horrible service) to vzw, phones (samsung fantastic, droid x) should be here today. I have a question...

on AT&T I had 3 lines so I got the family txt thing added since I was the only one with unlimited data plan, I have since dropped one of the lines so now I'm just going to have these 2 smartphones with unlimited data packages...do I still need to pay for text/multimedia messaging on an unlimited data plan? would seem like your paying twice for something, no? thanks.
