WhatsApp Messenger is a cross-platform mobile messaging app which you can use instead of texting as it uses your internet data plan, so you don’t have to pay for SMS. So far so good. Free messaging? Yes please.It works whether you’re using an iPhone, BlackBerry, Android, Windows Phone or Nokia and messaging is usually extremely fast. You can also create groups, send images, video and audio media messages.
It’s great is you’re messaging people in the same country, or who you know are on wi-fi (and you are) as yes, then it is free. However, because it uses your internet connection, if you’re roaming, or if you’ve exceeded your data limit, then there will be charges.
WhatsApp Messenger uses your phone's internet connection to send and receive messages, pictures, audio, video, location, and contacts. As long as your phone is not roaming and you have not exceeded your data limit, messaging over WhatsApp should not cost you extra.
If you’re overseas and you’re on wi-fi you should not incur charges, however be aware that it’s all too easy to continue using it when away and without wi-fi and end up with a bill from your provider, so don’t let yourself get caught out.
WhatsApp has now grown to have a bigger user base than Twitter (although you are comparing chalk and cheese) according to an article in the Daily Telegraph a short while back. Have a read.
