Renew loads MicroSD cards full of Gospel media in the target language and then locks them to prevent media from being changed or erased. MicroSD Cards are small memory chips that can hold enormous amounts of digital media. Most of the world’s cellphones have MicroSD card slots, which makes this a great way to give Gospel media content to cellphone users. And once one person gets the media onto their phone, they can easily share it from phone to phone, initiating a viral spread of the Gospel!
