Shadytel is happy to announce the availability of GSM service at Toorcamp! All attendees will receive a SIM card compatible with any 900mhz or 1900mhz unlocked GSM phone. An API for creating SMS-based shortcode apps will be available, and all of our SIM cards support JavaCard STK applets for 1990s-style mobile development. All phone calls and text messages are completely free. See http://wiki.toorcamp.org/wiki/GSM for more information.
