An Educational DIY Mobile Phone

This neat little device is an open source mobile phone that you can build yourself.
Besides that, MAKERphone is also an educational device shaped like a mobile phone compatible with all mobile networks up to 4G.
Its purpose: to motivate people to explore, learn and create something new in a fun and interesting way.
