i have unlimited texts. i was wondering if picture messages and video messages counted as texts, or were something different. on our bill, we frequently get a small "data" charge of $2 a pop, but we have no idea what that charge is. we never go on the internet, download ringtones, use the gps, or any of that stuff. the only thing it could be is picture messaging, but from what i have read, those count as texts. also, i have read about "megabyte usage charges". does that mean if i use more memory, say if i record a lot of videos, that it charges me per mb that i have taken up?
