Hi. The only prepaid plans in the US I know of, which let your unused data roll over to next month(s) are the Simple Choice Prepaid Plans by T-Mobile US and only from now on. They call it "Data Stash" and used to limit it to postpaid. Effective end of March 2015, it will be on some prepaid plans too: more info. Note: only Simple CHOICE prepaid plans, not the Simple prepaid plans are eligible: see here. I've marked the specific plans in the table above.
