Previously, when using your mobile phone, SMSs and mobile phone calls were the only way to communicate but now with access to relatively high speed internet on your mobile phone it makes communicating on social networks much easier. People are using social networks rather than SMSs and mobile phone calls as social networks can offer you so much more. For example, when visiting Facebook, not only can you see the recent updates from your friends but you can also view events for the week ahead.
Visiting social network sites on your mobile phone can even be cheaper than a phone call, encouraging many to switch to social networks to communicate via their mobile phone. Opera mini, for example, provides a cheap and easy way to access the internet via your mobile phone. Last year, Patricia de Lille complained that South Africa had the highest mobile phone call costs in the world.
