When Whatsapp launched, SMS still wasn't free, the exception being some carriers that offered "free" SMS to numbers of the same carrier if the sender was on a premium coverage plan. In sum, majority of the population was still paying $0,10-$0,20 despite already having data plans. So it was an easy win for WhatsApp.
