There is no doubt that your friends have begged you to get a BlackBerry, or the only reason you got one is for BlackBerry Messenger. Now before I go on, the BlackBerry Smartphone is still a great phone, which goes beyond just the Messenger service, but it is not the answer.
WhatsApp is an application that is available on most of the popular smartphones like Android phones, Nokias, BlackBerries and of course the iPhones. It allows you to send messages free of charge (of course data rates apply) much like BlackBerry Messenger. This allows you to chat to your friends no matter what phone they are using.
This brings me to the feature that makes WhatsApp a winner for me; WhatsApp does not need you to add a contact via a pin or ID. You simply message all your contacts on your phone if they have WhatsApp, if they don’t you are given the option to invite them to it. This feature makes the application painless and in my opinion is the reason why it has become so popular; besides the fact that it does work on all phones, unlike BlackBerry Messenger.
