Welcome to our Community Forums! Thank you for your first post and I'm very sorry to hear that you're experiencing some issues with accessing your Voicemail! I understand how frustrating this must be.
We recommend our customers taking a look at our Using Virgin Mobile Abroad page to see what needs to be done before your travels.
You can take a look at our website to see How To Set Up Virgin Mobile Voicemail to see what needs to be done to ensure that you can use your Voicemail abroad. However, as you're abroad already, I'll be happy to help amend this for you via Private Message. Please keep an eye out for a purple envelope at the top right corner of your Forum page. I will be in touch soon.
