Message troubleshooting

I cannot send messages

Try performing the following actions:

•Verify that your BlackBerry® device is connected to the wireless network. If you are not in a wireless coverage area, your device should send the messages when you return to a wireless coverage area.

•If the menu item for sending a message does not appear, verify that you have added an email address or PIN for your contact.

•If you created an email address or added an existing email address to your device using the email setup web site, verify that you have received an activation message on your device from the BlackBerry Internet Service. If you have not received an activation message (the message might take a short period of time to arrive), use the email setup web site to send a service book to your device.

•If you have not received a registration message from the wireless network, register your device. In the device options, click Advanced Options. Click Host Routing Table. Press the Menu key. Click Register Now.

•Generate an encryption key.
