This eco-friendly phone is the world’s first carbon-neutral cell phone. Made with recycled water bottles, this cell phone is cost effective, yet comes with abundant features. Call quality of this Motorola Renew W233 mobile phone is pretty good too. Certainly, there are some drawbacks on this mobile device. First, the Motorola Renew W233 has a low-resolution display; second, it offers only few features; and third, it doesn’t have a side-mounted volume rocker.
