BBM lets you protect your privacy. You control it:
You chose how to share your information - BBM uses PINs instead of phone numbers or email addresses so that it's more private, and you always control who can contact you
You chose your contacts – 2-way opt-in means you have control over who is able to message you
Chat and Share with many at once:
Groups – BBM groups help you share pictures, lists, and appointments with group members. You can even be in a group with people who aren't part of your own BBM contact list.
Multi-person chats – Invite multiple contacts to have a chat together.
Broadcast messages – Send a message to multiple BBM contacts at one time.
Create your own BBM profile:
Post a profile picture using images, pictures or even animated pictures (GIFs).
Update your status to let people know what you’re up to or how you feel
