The modu handset, unveiled at Mobile World Congress in Barcelona this year, weighs 41g and measures 2.8 inches x 1.4 inches x 0.3 inches.
modu is made up of a core phone, designed to be encased in a variety of modu ‘jackets’.
modu vice president of marketing Zack Weisfeld said: “This is a great achievement for a team that has worked tirelessly to take modu from the drawing board to producing full working devices in less than a year.
"From the outset, modu’s tiny dimensions and super light weight have been fundamental to delivering the disruptive, modular communication concept that modu embodies.
“modu has already made a huge impact since its launch at MWC, with mobile network operators, consumer electronics manufacturers and other potential partners all attracted by our revolutionary approach.”
