About every month $9.99 is billed to my virgin mobile account due to XTRAs charges. Strange point, it's only be happening around two months. I hardly ever use my hpone for txt messages. I'm not using or sighned up for the pattern or anything fancy, I'm just using my phone normaly.

or maybe going over your minutes.
