How do I change the message on my magicjack phone?

From Your Computer
Step 1 Launch the MagicJack software on your computer.
Step 2 Press the "Vmail" button.
Step 3 Press "0" to personalize settings.
Step 4 Enter your password when prompted. The default password for MagicJack is "1234." Enter that password if this is your first time setting up voice mail.
Step 5 Press "0" to get your mailbox options.
Step 6 Press "1" to record a message that plays when you are unavailable, or press "2" to record a message when you're busy. The first message plays when your Internet connection is out, and the second plays when you're on another call.
Step 7 Press the "#" key to end the recording.
Step 8 Listen to the recording by pressing "1" again, and press "2" to accept the message or "3" to re-record your message. Repeat this process until you're happy with your message.
