Cheap calls from South Africa

An instant messaging service is helping South Africans chat at cheaper rates. Download mig33 onto your cellphone, register for free, follow the authentication prompts and you're mig33-enabled. mig33 was released in December 2005 and offers not only free instant messaging, but also uses VoIP (voice over internet protocol) technology. Recently mig33 added a prepaid calling-card service that reduces the cost of international calls. In South Africa the cards are available in denominations of R10, R20, R50 and R100 from cellphone retail outlets.
