Just call 121 from your Vodafone phone to check your voicemail.
If you have Visual Voicemail, choose the message you want to hear in your voicemail tab, and then hit play.
If you’re travelling abroad, call +44 7836 121 121 and enter your security PIN (this will need to be set up before you go abroad).
Please note: if you’re a Pay monthly customer or have a Pay as you go Big Value Bundle, this will use minutes from your allowance. If you have no remaining minutes or you’re in a roaming zone where you can’t use your plan like at home, standard call charges apply.
