You can get cash for mobiles, and you should always send in your phone for recycling whether you get any money or not. And you will be surprised at how much money you can get for your old phone. What these recycling companies do is refurbish the phones and then sell them to third world countries that have a need for them. Their technology is such that your older phone is perfect for their requirements. However, even in cases where your phone is not worth any money because it is the wrong model or it cannot be repair, you should turn it in for recycling. These phones contain heavy metals that when disposed of in a trash can, will end up in a landfill, that over time will begin to leak. These heavy metals can eventually find their way into the underground water and from there into the drinking water of a community.
