Hi Lizinbriz,
A warm welcome and thanks for posting on our community forums. We can certainly try and help you with this issue and get your voicemail pin reset for you so you can access your messages.
Unfortunately, as you did not set a voicemail pin up in the UK before you travelled abroad, any network changes are best done whilst you are connected to a UK network. If they're done abroad we cannot guarantee they'll take effect until your phone connects to a UK network again, however we will try for you.
I will pop you over a private message to take some details from you. Please click on the purple envelope to accept the chat.
Kind regards Jodi.
