AT&T has sent my phone an automated messege informaing me I have used 90 percent of my data usage. I do not want be billed an additional 15.00 monthly as I can only afford the 200mb plan!!!!! What can I do to DECREASE data usage? I know I do not stream video or music on my phone. I am guilty if sending people pics attacted to texts which I suspect is using a good deal of data. Otherwise I realize that I cannot surf the web via safari or whatever and not expect data usage. I noticed that my data usage seemed to jump up after installing Facebook? I try ot to check my email via phone also. What are all of the things I can do to put a cap on this data usuage?
