Set up o2 voicemail

O2 Voicemail 901 is set up automatically on all new O2 phones, with a default greeting ready before you even touch a setting. To access your messages, dial 901 from your O2 mobile. The first time you call, O2 will prompt you to create a PIN to keep your mailbox secure.

Do I need to do anything to activate O2 voicemail?

For most customers, nothing. O2 Voicemail 901 comes pre-enabled with a default greeting, so callers can leave messages from day one. If you find voicemail has been switched off on your account, dial 1750 free from your O2 mobile to turn it back on. That call takes under a minute.

As O2's official help page puts it: "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."

How do I listen to my voicemail messages?

Dial 901 from your O2 mobile. You will be asked for your PIN, then you can play, save or delete messages. That number works any time, day or night, and the call to 901 is free within your allowance.

Android users who find voicemail is not ringing through should check their call settings and confirm the voicemail number is set to 901. That fixes the problem in the majority of cases.

How do I turn O2 voicemail off or back on?

• To switch voicemail off: dial 1760 free from your O2 mobile.
• To switch voicemail on again: dial 1750 free from your O2 mobile.

Both calls are free and take effect quickly. Bear in mind that while voicemail is off, callers will not be able to leave you a message.

What is O2 Call Alert and how does it differ?

O2 Call Alert is a separate service that notifies you of missed calls without storing a voice message. You cannot run Voicemail 901 and O2 Call Alert at the same time. If you want to switch from voicemail to Call Alert, dial 1710 free from your mobile. According to the O2 Community guide: "If you use Voicemail 901 and you want to replace the service with O2 Call Alert, call 1710 free from your mobile."

To go back to Voicemail 901, dial 1750.

Can I use O2 voicemail when abroad?

Yes, but there is a step to do before you travel. Call 1780 free from your O2 mobile whilst you are still in the UK, and O2 will text you a roaming number for your voicemail. Save that number before you leave.

When you are abroad, listening to a voicemail costs the same as making a standard call back to the UK, so it sits outside your normal allowance. Checking messages briefly and then hanging up keeps the cost down.
