4. Donate to charity
Several charities accept old phones for donation, though it's worth remembering that these groups likely won't physically give your old phones to people in need. Rather, they work with phone recyclers and sell your donated phones to them. A nonprofit group called Cell Phones for Soldiers will take your "gently used" phone and sell it to recycling company ReCellular. It will then use the proceeds to buy calling cards for soldiers. The National Coalition Against Domestic Violence works with another recycling group in a similar manner.
