Use more data, win more prizes. It may sound counterintuitive, but that's exactly what Russian operator MegaFon is offering to its subscribers, as part of a curious 3G promotion. It all began back in November, when the provider announced a rather straightforward contest: customers who downloaded the most data with their 3G modems would be awarded prizes worth up to one million rubles (about $33,000), including a $5,000 vacation. According to Russian news site C News, MegaFon launched the campaign in order to showcase the expanse of its data network, which apparently covers more than 80 percent of northwestern Russia and offers speeds of up to 21Mbps. The promotion came to an official close on January 31st, with the coronation of a lucky winner who, over the course of a single week, managed to scarf down 419GB of data on the company's 3G network. MegaFon didn't offer usage statistics on the second and third place winners, nor did it say what they won for their efforts, if you wanna call them that.
