Hello, I recently inserted my new SIM card and today have been left a Voicemail.
Normally, I would just hold down the 1 button and it would directly ring my Voicemail. When I tried this today, it asked me to input my Voicemail number. I assumed (wrongly) this would be my mobile number which I entered but got the message "sorry but the person you've called isn't available".
Could anybody point me in the direction of how to obtain my correct Voicemail number?
