I just got this to my email ~ so ~ I have 20 of the plan remaining? 20 what? 20 MB? Will that last three more days? Or three more hours? I have never gotten this message before ~ I am glad they give you notice. Because I am running low tells me that I have been using my 3G more than usual? Right? Or am I just not getting this?
