If you managed to score yourself a new mobile phone for Christmas, don’t let your old one gather dust or become a worthless spare.

Selling your old phone is a great way to get a few dollars in your pocket and you may be surprised just how much you can get.

Popular phone from brands like Apple, Samsung and Google can hold their value quite well even after a couple of years if they’ve been well looked after.

Now you can either sell them yourself using ebay, Facebook or gumtree (beware of scammers)…but if you’d happy to take a few less dollars and turn that device into cash sooner, try a website like MobileMonster.com.au that can offer you a fixed price for your handset based on its condition.

One important tip: make a backup of everything on your phone then factory reset it before you sell!
