Sky Mobile now lets you trade in unused data for money off a range of products, including smartphones, tablets and mobile accessories.
The scheme is called Piggybank Rewards. Like other mobile networks, Sky already lets you roll over unused data from the previous month into next month's allowance. But this scheme extends that to money off actual physical products.
It includes devices from the likes of Apple, Samsung and Sony.
You don't get to choose any device, though. Sky will pick a range of products each month that are eligible for the money off deal. For example, you could cash in 5GB of unused data on a range of iPhone cases, or you could spend 20GB on a new Bluetooth speaker.
But bear in mind, it's limited to a maximum of £50 off a new device.
"When we launched Sky Mobile, we wanted to offer the best possible deal to our customers. Automatically saving their unused data with Roll was a big part of this," says Sophia Ahmad, Director of Sky Mobile. "Our customers have saved over £50 million worth of data so far, which would have been lost with other networks. Now we’re improving Roll even more with Piggybank Rewards - turning customer’s unused data into savings on new phones, tablets and accessories.”
