There are literally tens of thousands if not millions of mobile phones which have fallen into disuse over the past decade. Many of these mobile phones are simply lying forgotten about in a drawer somewhere. These mobile phones contain some quite unpleasant chemicals and heavy metals, which if sent to landfill can pollute land and water. It is therefore important that you dispose of your old mobile phone safely. What you may not know is that even old obsolete handsets have a cash value. There are many different mobile phone recycling companies who will pay good money for an old handset. They will either reclaim precious metals and other valuable components from the phone before disposing of the rest in a safe and responsible manner, or they will sell the phone as a working item to another user. Often mobile phones shipped abroad to developing economies where people cannot afford the latest handsets, but are more than happy to use an older preowned handset that does the job perfectly well.if you want to sell your old mobile phone all you need do is visit a website for one of these recycling companies, get a cash price quoted for your old mobile phone, post it off to them using a label provided and wait your cash to be sent back to you.
