Unless you roll it over, the unused mobile data you paid so dearly for is lost in time, like tears in ... rain. For a limited time, however, Virgin Mobile customers in Australia can transform those dead digits into phones, drones and other swag. To be sure, the "data auction" is a publicity stunt that mostly benefits Virgin, since there's but a single prize each day over the month-long promo. In addition, you have to bid all your remaining data, so you can only win once.
However, some of the items are pretty decent, including a Samsung Galaxy S7, DJI Phantom 3 drone and the grand prize, a $40,000 all-expenses paid trip to a private island in Fiji. If nothing else, the auction draws attention to the fact that while some subscribers do abuse unlimited data, most use a fraction of their paid allotment -- to your carrier's benefit, of course.
