BlackBerry Messenger, an instant-messaging application available only on devices made by Research In Motion, uses each smart phone's personal identification number, or PIN, to chat in real time. Rather than counting as text messages, BlackBerry Messenger, known as BBM among users, communicates via data transmission, so a data plan is required. To test your messenger application, which comes preloaded on every BlackBerry smart phone, look for several indicators of success.

Open the BlackBerry Messenger application from the home screen. Press the menu key, then choose "Options" and make sure "Allow Forwarding of Request" is set to "Yes." Press the back key once to return to the main BBM menu.
Press the menu key and select "Add a Contact."
Invite a contact via e-mail or PIN. Highlight a contact from your address book, then choose where you want your message sent, and select "OK." The contact will have to accept your invitation before his PIN will be added.
Add a PIN to a contact. If you already know the PIN, open the contact from your list, then press the menu key and select "Edit." Scroll down and type the PIN in the field.
Open the BBM application from your home screen. Press the "Menu" key, then select "My Status."
Select "Available," and type a short message if you wish.
Click "OK" to set your status. If BBM is working properly, your contacts can highlight your name, select "Contact Info" from the menu and view your availability.
View a contact's availability. Highlight the contact's name, then press the "Menu" key and "Contact Info" to see whether that person is active or busy. If you want to be notified when a busy contact becomes available, with the contact availability screen open, press the "Menu" key and select "Set Alert."
From the BBM application, select a contact's name.
Type your message in the box at the bottom of the screen. When finished, press the menu key and select "Send," or simply press the "Return" key after typing, and it will automatically send.
Look for a checkmark with a "D" next to it. This means your message was delivered. Look for the "D" to turn to an "R," indicating the contact has read your message.
Be aware of the signs of failed delivery. These include a clock icon that never turns into a check mark and the absence of a "D" and "R."
Tips and warnings
- If after testing you find your BBM application isn't working, contact your wireless provider to make sure you are properly set up with a personal BlackBerry Internet Service plan. If you are on a BlackBerry Enterprise Server plan through your workplace, contact your administrator for help with troubleshooting.
