With BBM, you can chat and share in real time with your friends, family, and coworkers. You control your contact list and decide who can add you as a contact. During a BBM chat, you can see when someone has read your message or is typing a reply, and you can share pictures and other files.
Besides messaging with your BBM contacts, you can also chat with several people in multiperson chats and BBM Groups.
