WhatsApp Messenger is a smartphone messenger available for iPhone, Blackberry, Android, and Nokia phones. WhatsApp uses your 3G or WiFi (when available) to message with friends and family. Switch from SMS to WhatsApp to send and receive messages, pictures, audio notes, and video messages at no cost (see moderator clarification below). Free for the first year!
The last time I checked Ovi Store, you get charged for downloading this app. But now, you can download it for free for the first year - I've just downloaded this app yesterday. I'm not too sure what will happen after first year finishes though. I have been using whatsapp for iPhone for quite sometime and I personally think its a good app.
1) You first have to sign in,
2) Click 'send to mobile', you will get a sms (which you will be charged as normal SMS - $0.28 for 3 customers) with the link to download it.
3) Open the link
4) Download the app (you can save on data charges if you download using WIFI)
5) Install and you're ready yo use Whatsapp.
Hope this will benefit some of you.. :)
mod - such applications typically use your Internet allowance, to transfer the media.
Once you have used up your Internet allowance, you will be paying excess fees.
