To keep your messages secure you need to set up a voicemail PIN. We’ll ask you to set one up the first time you call 901, or if your phone’s been reset.

Voicemail 901 comes with a standard greeting. To personalise your message, just:

1. dial 901 from your O2 mobile
2. press *
3. choose option 3
4. follow the prompts to personalise your message.

You can change your greeting as often as you like.

While you're listening to a message you can press:

• 0 to pause or continue
• 4 to skip back five seconds
• 6 to skip forward five seconds.

After you've listened to a message you can press:

• 1 to replay it
• 2 to save it
• 3 to delete it
• 5 to return the call
• 7 to forward the message to another mailbox or leave a voicemail for the caller (Pay Monthly customers only)
• 8 to hear who called you and when
• 9 to reply by text (Pay Monthly customers only).

If you're a Pay Monthly customer, calls to 901 are included in your call tariff allowance. Calls made outside your allowance are charged under our extra charges guide.

Before you travel, you'll need to know your PIN. Calling 901, as usual, works in most countries.

If it doesn't, call 07860980980 free from your mobile and enter your mobile number and mailbox PIN when prompted.

Depending on which country you're in, you'll either go straight to your messages or to your voicemail greeting.

If it's your greeting, press * and type in your PIN.

If you forget your PIN while abroad, try texting RESET to 802901.

If that doesn't work, contact us and ask us to reset it.

You'll then need to change your PIN before you can listen to your messages.

Please note: Changing your reset PIN only works if you can access your voicemail using 901.

You can change your pin any time, just:

• call 901
• press *
• Choose option 4
• Follow the instructions for setting up a PIN.

When you set your PIN, try to choose a number that’s difficult to guess. So don’t go for repeat or consecutive numbers, or the year you were born.

You can reset your PIN at any time, just text RESET to 802901. You'll be sent a temporary PIN, which you’ll need to change before you can listen to your messages.
