I use Voicemail all the time in UK with no problem.
I am now in Spain and someone left me a message on voicemail but when I try to access it in the way I would when I am in the UK I get a message saying that "That service is not available". I have an iPhone and it accessing Orange network most of the time I am in Spain.
Can someone tell me what I need to do to be able to access my messages on Voicemail while I am in Spain ?
For anyone else who has this issue - this was resolved by changing the network provider used in Europe. My mobile has automatically selected Orange, I changed this to another provider and was able to access my voicemail.
