About MobileSPhere

MobileSphere provides 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 users. In 2009, MobileSphere created the concept of ringless voice messaging and entered the market with slydial. Slydial is a voice messaging solution that enables consumers to connect directly to another person’s mobile voicemail. MobileSphere filed and was awarded the patent on the ringless voicemail technology, shortly thereafter. Following the success of slydial, MobileSphere launched slybroadcast in 2014. Slybroadcast allows for one audio messages to be delivered directly to the voicemail-box of thousands of mobile phones, instantly. Recently, MobileSphere entered the multimedia messaging market with slyText, the industry’s first two-way web-to-mobile multimedia messaging service enabling interactive, real-time communications from the web to mobile phones.
