This is the oophone project. "oophone" means "our own phone".

We are building our own quad band cellular phone, based on a SIM900 cellular communication module, a 32bit microcontroller and an ePaper display.
The initial spark came from stsp who found an arduino cellphone project and promptly bought five quad band sim modules.

Large parts of this project are in German. We use English occasionally to ease communication with some of us that are not fluent in German.
