Now I have one friend who works for Verizon and says it doesn't use text messages and another that says it strictly uses data.
I have a BlackBerry 8330 for Verizon and idk if I want to activate it, I use IM apps all the time, all day long
anyway, I was told and confirmed this on the Verizon site, that IM uses a text message, now, I would get the 500 text plan, so I wouldn't have to pay for unlimited, because I normally dont need it
