1. Press and hold the "1" key on your T-Mobile phone. This will automatically dial the voice mail number for your account. If this method does not work, you can also dial "123" from your handset to access the voice mail servers. 2. Listen to the directions for first time setup. If you are prompted for a security code, use the last 4 to 9 digits of your telephone number. 3. Follow the prompts to record your personal greeting, or choose the standard greeting that mentions your telephone number.
4. Follow the prompts to set up your personal voice mailbox security code. You will need to enter this code any time you call your voice mail. This prevents unauthorized users from hearing the messages saved to your account.
5. Make a test call to your number from another cell phone or landline phone to determine if you have successfully activated your voice mail.
