Old models of cell phones reach increasingly high and surprising prices, so it is worth taking a look at some forgotten drawer in our home where we may have a real treasure in 2025.

Cell phones tend to be relatively easy to recycle, at least compared with other electronics. Here’s a closer look at why and how to recycle a phone.

I bet somewhere in your house is an old, unused cell phone. It is estimated that half a billion retired cell phones are just sitting around in the U.S. alone. They're phones that could be recycled.

Our teen has had a cell phone for two years. She's made a few mistakes, such as making friends through gaming apps, but we've worked through them.
