Voicemail 901 is available to all O2 customers and is ready to go on all new O2 phones.
Before you travel, you’ll need to make sure you know your pin, so if you haven’t set this up or it’s been reset, call 901 and follow the instructions
When abroad, just call 901 as usual to access your voicemail.
This will work in most countries. But where it doesn’t, call 1780 free from your mobile or +447802 090 100 and we’ll send you a text with the correct number to call for voicemail.
Depending on which country you’re in, you’ll either go straight to your messages or you’ll go to your voicemail greeting. If it’s your voicemail greeting, press * and enter your PIN.
If you’ve forgotten your PIN, you’ll need to contact your dedicated customer service team and ask for it to be reset. You’ll then need to change your PIN before you can listen to your messages.
