so i dont use the web, i dont stream videos, and when i'm at work or home i use wifi. but i average being out of work/home atleast 5 hours a day, all day on weekends. i get close to 200 emails a day and respond to about 10 a day. i'm logged into AIM almost 24/7. so my questions is there data usage for not even checking/reading/responding to emails? im assuming there's got to be some type of data usage just for the push notifications. and does AIM use a lot of data, chatting or not chatting? those are the two main things i use the most. and if 2gb is more than enough, can i get away with 200mb?
