  • How do I change my voicemail PIN?

    Having a PIN means that you're the only person who can access your messages. You'll be asked to set up your PIN the first time you access Voicemail 901 or whenever it's been reset to the default.

    You can change your PIN at any time by:

    - Dialling 901

    - Pressing * for greetings and mailbox settings and then 4

    - Following the prompts

    Your PIN also allows you to access your messages from any touchtone phone by:

    - Calling your O2 mobile number

    - Interrupting your greeting by pressing *

    - Entering your PIN

  • How can I reset my voicemail PIN?

    Text: “reset” or “RESET” to 802901.

    You will then receive a text back which has a random 5 digit number. Then dial 901 – where you will be asked to enter the random 5 digit number from the text.


    You'll then be asked to enter a new PIN. Anything between 4 and 10 digits can be used except for 8705.


    If you have a personalised PIN you will need to contact Customer Service to have your PIN reset. A personalised PIN will have been set up by you and every time you dial 901 you will be prompted for it.
