I think you have Verizon on your Storm. Anyways, they don't have that. It would be pretty useless because the plans are unlimited. This is assuming you have Verizon or an unlocked Storm with TMobile or ATT. I'm only saying this cause I know, some what, understand their data plans.
I don't know how other phone providers work.
But if you know you have unlimited then it's kind of useless.
Or saying it wasn't it still doesn't have one.
I know with Verizon you can dial #DATA and it sends a text with your usage.
