I've been using AIM on either my Motorola V300, Samsung E105 or Nokia 3390. I know every action u do such as Signing on, signing off & IM a buddy counts as 1 text message. Currently I have 10 buddies in my "Mobile Device", 4 of them are online. It seems that if I Sign on or off, I'm wasting a text message for every person that is on my "Mobile Device" buddy list. I've talked to 5 or 6 Customer Care Reps. & most of them can't really explain why is that. A few ppl I know & myself included noticed that because we are going to the roof with Text Messages charges, not to mention we all have Text Messages packages.
Since I can't really get a straight answer from either Customer Care Reps & Text Messages Reps; I wanna know if any of u know more about AIM and what are the actual charges as far as Signing On or Off, IM'ing people, etc.
