Nimbuzz Messenger is an application that helps you communicate with all of your phone and social network contacts.

On one side, Nimbuzz Messenger gives you the ability to make free international calls, so you can talk to anyone without having to pay one cent (of course, the person you're calling will need to have Nimbuzz installed on their phone as well).

On the other side, you can synch Nimbuzz Messenger with other instant messaging services like Facebook, Yahoo Messenger, and Gtalk, to create one app from which to communicate with all of your friends and contacts. You can also create groups of contacts and chat rooms to help you stay organized.

One of Nimbuzz Messenger's most interesting features is the option to receive and save messages even when you're not connected to the Internet. In other words, your phone will hold onto the messages until you find a connection and can read them yourself.

Just like with Viber or Skype, Nimbuzz Messenger allows you to make calls to mobile phones, as long as you pay a small fee. In any case, the fee is quite cheap.

Nimbuzz Messenger is a good option among the plethora of similar communication apps that you can find in Google Play or the App Store.
