1. Why should I recycle my mobile device?
There are several reasons why recycling your mobile device makes sense. By mailing or dropping off your mobile device at a recycling drop-off location, you are doing something positive for your local ecosystem by diverting waste from your local landfills. Recycling your wireless device also decreases the amount of raw materials that would otherwise be needed for manufacturing new products.
