The document discusses the development of a SIM card designed for Muslims. It was created by a Greek engineer to address the lack of Islamic prayer and worship features available on basic cell phones in Asia and Africa. The SIM card allows users to track the direction of Mecca for prayers, receive accurate prayer times, and convert calendars. It aims to provide these functions for over 1 billion feature phones that cannot install apps. The SIM card has been showcased and its wider availability is hoped to come soon.
