The majority of mobile phone users around the world use simple feature phones which, unlike smartphones, do not have advanced storage or secondary communication options like Wi-Fi and Bluetooth. Abayima wants to build an open source application that people can use to store information to SIM cards  – effectively turning the cards into storage devices and their mobile phones into e-readers. This app is particularly useful for sharing news and information in countries where communication networks are unsafe to use due to surveillance or where authorities or other circumstances have shut off access to the Internet altogether.  The team has successfully piloted a program with Ugandan activists during the country's 2011 elections, while all SMS traffic in the country was monitored for voices of dissent. With challenge funding, Abayima plans to build the kit as an open source, full service, easy-to-use platform which enables publishing to SIM cards.
