Unihertz Atom is a tiny, rugged 4G smartphone with a 2.45 inch display

From Liliputing.com: the Unihertz Atom is a tiny, rugged 4G smartphone with a 2.45 inch display. Unfortunately no microSD slot, but this might change, if enough customers complain about this. Update: if there is enough customer feedback, there might even be a pro version with high res screen and microSD!
