  • Publication number: 20050233775
    Abstract: A mobile phone provides religious prayers and has a memory module, a voice module, a display module, a processing module, and an interface module. The memory module stores at least one set of prayer voice data and at least one set of religious text data. The processing module retrieves the prayer voice data and the religious text data from the memory module and plays them through the voice module and/or the display module. The user can also use the interface module to set the processing module to play the prayer voice data or the religious text data, and to set the prayer voice data for ring tone of the mobile phone.
