About MobileSPhere

MobileSphere focuses on providing mobile communications and mobile messaging solutions to enterprises, non-profit organizations, and consumers. Founded in 2003, MobileSphere pioneered the wireless international long distance market with its CellularLD solution, enabling U.S. consumers to place low-cost overseas calls from a mobile phone. Shortly thereafter, MobileSphere began partnering with major universities, enterprises and wireless carriers to develop and launch tailored international calling solutions for mobile subscribers. In 2009, MobileSphere invented the voice messaging market with slydial, a new patented voice messaging solution that enables consumers to connect directly to another person’s mobile voicemail. In 2014, Slybroadcast was created which allows for one audio messages to be delivered directly to the voicemail-box of thousands of mobile phones with our patented voicemail delivery technology. Recently, MobileSphere entered the multimedia messaging market with Joopz, the industry’s first two-way Web-to-mobile multimedia messaging service enabling interactive, real-time communications from the Web to mobile phones.
