Nimbuzz allows you to make calls, chat online, exchange instant messages and send files from your phone for free.
Making long distance or international calls from your mobile phone can be so expensive that it's almost better to not stay in touch. Install Nimbuzz on your phone, and you'll be able to talk to people all over the World for free - at least in theory.
Nimbuzz pulls all your contacts together in one place, so you can exchange messages with all your friends on networks such as MSN, AIM, Yahoo! Messenger, Google Talk, Jabber, Facebook, or MySpace.
The user interface in Nimbuzz combines all of your contacts from all these various networks into one place, and you can see who is online at any time. Everything is presented in a very neat and clear way: contacts are ordered alphabetically and each has a different icon depending on which network they belong to.
To start connecting with Nimbuzz you simply need to tap on a person's name then select an icon from: Call, Chat or Mail. Of course, the call option is only available for the services that support VoIP (Google Talk, MSN, Skype, etc.) but the voice quality is generally very good if you have a strong signal.
There are a few things that annoyed us about Nimbuzz. For instance, it sometimes doesn't display Facebook contacts in the Contacts list. Also, it persistently says when a new mail was sent to our Gmail or MSN accounts, but didn't actually let us read the email. Even when we deleted these alert emails they kept coming back.
If the developers of Nimbuzz can iron out these flaws then it will cement its place as the best app for free, multi-network chat on the iPhone.
