Donations Via Mobile Phone See Massive Growth, Single Touch Now Powers a New Way to Donate to Charities – Following the disaster in Haiti, mobile donation programs are seeing a dramatic increase in usage. Donations via text message continue to be popular and now donations via voice calls to Mobile Dialing Codes (MDCs) are seeing tremendous growth due to their ease of use and convenience. Single Touch Systems (OTC Bulletin Board: SITO) provides the platform for mobile giving via Charity Call™, where AT&T subscribers dial #505 and select a charity or cause of their choice and simply make a one-time donation of $25.
