Like many, I guess, I recently discovered I couldn't access my Voicemail while abroad (Spain). The instructions here: https://www.virginmedia.com/help/virgin-mobile-voicemail-abroad state that to do that you need to set it up in advance and then press # and enter your PIN (I have roaming enabled). However, I don't use a PIN in the UK. (I have previously set up a PIN but found I could access my voicemail without it). So do I need to set up a PIN again, and does that mean I will then have to use a PIN in this country?
