dude..perhaps u din read from its page....

NOTE I: WhatsApp DOES NOT use SMS for chat. WhatsApp will use your Wi-Fi connection if Wi-Fi is available. If no Wi-Fi is available, WhatsApp will use your EDGE/3G connection - therefore it is recommended that you have unlimited data plan in order to use WhatsApp.

NOTE II: WhatsApp is currently not available in Mexico, Malaysia, Indonesia, Thailand and India.
