Our website has helped to pay out an average of around £26 for every old handset that we receive.
It couldn't be simpler to make a few quid and help save the planet at the same time as two of our readers proved. Bricklayer Michael Russell (pictured above), 39, went on the hunt for his family's phones with daughter Danielle, 11.
And as Michael is a married dad-of-five the duo were able to find TEN old mobiles and pocket an amazing £290. Michael, from Gosport, Hampshire, said: "I had a couple of old phones lying around the house, and I got a couple from my mum and stepdaughters. It's easy money that me and Danielle have divvied up."
So far Michael and Danielle, pictured here, are our top earners. Experts reckon there are 80 million old mobiles in UK homes, worth from a few pounds to £206. Your old mobiles will be reconditioned to help Third World people or broken down for components. Recycling helps cut greenhouse gases from landfill and saves making new phones.
So far we've received 19,000 phones in six weeks - so now it's your turn to get a share of the cash.
HOW TO GET YOUR CASH
