Voicemail 901

Voicemail 901

Voicemail 901 is your answerphone. It answers any calls you miss and lets you know when you have new messages. It's available to all O2 customers by calling 901 and it’s ready to go on all new O2 phones. If ever it's switched off, you can turn it on by calling 1750 free from your mobile.

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 much does it cost to use voicemail?

If you're a Pay Monthly customer, calls to 901 are free. If you're a Pay As You Go customer, they’re charged at your standard tariff rate. If you’re abroad, it costs the same to listen to a voicemail as it does to make a call to the UK. There’s no charge for receiving a message if you don’t listen to it.

How do I use voicemail when I’m abroad?

Before you travel, you’ll need to make sure you know your PIN.

Calling 901 as usual works in most countries. If it doesn’t, call 1780 free from your mobile, or +44 7802 090 100, and we'll text you the right number to call.

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 when you’re 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 it before you can listen to your messages.

How do I change my PIN?

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.

What if I forget my PIN?

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.
