With BlackBerry Messenger (BBM), you can chat and share in real-time with your BlackBerry contacts. For example, you can see when someone has read your message and when the person is typing a reply. You can also share pictures, voice notes, your location, and files.
You can use BBM Groups to plan events, delegate tasks, and see when members add or change items. A social space is created in BBM for each of your groups so that you can chat and share pictures, lists, and calendar appointments with up to 30 people at the same time.
You can use BBM over a Wi-Fi connection, such as while you're travelling.
