The first time that you open BBM, you are prompted for your BlackBerry ID. If you have used BBM before, consider the following:
- If you are switching BlackBerry devices, you can use the Device Switch feature in BlackBerry Link on your computer or on a device running BlackBerry 7 or later to transfer your device data, including your contacts and groups from BBM 6.2 or earlier, to a new device.
- If you previously associated BBM with your BlackBerry ID (for example, on your current device), you can sign in with the same BlackBerry ID to restore your BBM data over the wireless network.
After setting up BBM, your contacts, profile, channels, and groups are automatically backed up over the wireless network based on your BlackBerry ID. It's still a good idea to regularly save a backup file for your device on a computer using BlackBerry Link in case your device is lost, stolen, or corrupted.
I used the wrong BlackBerry ID for BBM
If you accidentally sign in to BBM using the wrong BlackBerry ID, you must delete all of the data from your BlackBerry device to use a different BlackBerry ID.
- On the home screen, swipe down from the top of the screen.
- Tap Settings > BlackBerry ID.
