I have just spent $99 on a travel sim and received a voicemail message. When I try and connect it says I have no credit when I have unlimited NZ calls. It seems that I have to topup another $20 to receive this message for 20c! Is that correct because it can't be right and should have been made clear and up front when I purchased the SIM at Vodafone Auckland Airport?
I have tried to find a way of turning off voicemail using my online account or handset but can find no information on what is a standard feature in the UK.
If I have got this right, please will you advise how to switch off my voicemail.
