Data subscription plans for mobile devices are still quite expensive in every part of the world where it is offered. What’s more, if you’re planning on saving it for emergency reasons and it turns out such events never really comes, the data allowance you paid for is lost. That is the case if you don’t roll it over. Now, Australian telecommunications giant Virgin Mobile wants to alleviate your data consumption pains as it launches a new data auction that lets people reclaim their unused data.

According to a report from Mashable, Virgin Mobile Australia has a new plan that will let anyone bid on prizes starting April 15, 2016 until May 15, 2016 using their unused data allowances instead of cash. Furthermore, it will also work for anyone no matter which carrier they are subscribed to.

However, this also means that Virgin Mobile Australia customers that are currently under a data rollover plan will not be able to take part in the auction. After all, the Australian telco giant is the only company that allows its postpaid customers to have their data rolled over.

On the other hand, the prizes during the auction are quite attractive to boot, a Facebook post says. Prizes in the auction are devices such as a Samsung Galaxy S7, a DJI Phantom 3 drone, a Samsung Gear 2, and a trip for two people to Wadigi Island in Fiji that’s valued at $40,000 (US$30,890). Other prizes include concert tickets, a giant inflatable banana, a Mona Lisa Banksy-style print, a 12-month supply of jelly beans, art pieces, DVDs and more.

Participating in the auction is quite simple. You just have to take a picture of the leftover data on your latest bill and post it in the comments section of Virgin Mobile Australia’s daily auction post in its Facebook page.

While there are unlimited data subscribers who take advantage of the offering, there are also people that rarely used their data allowances. This might be a good way to put them into use.
