Hi @casweeney,
Welcome to our Community Forums! Thank you for your first post and I'm very sorry to hear that you're having some issues accessing your voicemail while abroad!
Before travelling abroad we would recommend setting up your Voicemail so you have access to your messages while travelling.
You can also take a look at our Using Virgin Mobile Abroad page to see what you can do to prepare for your travels and what we recommend doing before you go abroad.
However, as you're already abroad and need access to your Voicemail, I'll be more than happy to look into this for you and help resolve this issue. I will send you a Private Message to confirm a few details, so please keep an eye out for a purple envelope at the top right corner of your Forum page. I will be in touch soon.
Thank you.
