I just downloaded WhatsApp Messenger on my Android.
It is a smartphone messenger which replaces SMS. This app even lets me send pictures, video and other multimedia!
WhatsApp Messenger is available for Android, iPhone, Nokia, Windows Phone and BlackBerry and there is no PIN or username to remember – it works just like SMS and uses your internet data plan.
Download the latest version of WhatsApp Messenger and enjoy the service free for 1 year! During, or after free trial period you can purchase service for $0.99 USD/year.
Get it now from http://www.whatsapp.com/download/ and say good-bye to SMS!
Whatsapp offers an Internet-based SMS/MMS alternative, which doesn’t limit the amount of messages you can send or even which part of the world you’re sending them to. It works via the Internet, thus avoiding any charges that normal messages incur. What’s more, it’s cross platform, available for Symbian, Android, iOS and Blackberry. This means that anyone can communicate with anyone by just installing the app.
WhatsApp uses a similar routing technology as used for traditional SMS. In the registration process, your phone will send an SMS to itself to verify the number.
