eBuddy XMS is a free messaging app for BlackBerry that allows you to exchange text messages, photos and videos via the internet.

The app is like a cross between BlackBerry Messenger and WhatsApp. You can send messages and multimedia files with eBuddy XMS to anyone else who has the app installed, and vice versa.

To set up messaging with eBuddy XMS, you need to enter your phone number, then an activation code (sent to you via SMS). You'll be issued with a PIN number once you've entered the code. You can then chat with anyone on eBuddy XMS, adding them as contacts by entering their phone number or PIN number. There's an option to scan your phone book or Facebook friends for any contacts who are using eBuddy XMS.

In terms of features, eBuddy XMS lets you send photos, videos and emoticons, as well as text messages. Unlike WhatsApp, there's no option to record and send audio files, but there is a group messaging feature.

Providing you can convince your friends to switch from BBM or WhatsApp, eBuddy XMS makes for a simple, free messaging app.
