Hi, I have a new Sony Xperia and have followed instructions for setting up the voicemail. I have also sent a pin. However, on my front screen it says I have a voicemail but when I go into voicemail it says I have no new voicemails. It also shows I have a voicemail with the little icon on the top of the screen.
Sorry to hear that you're having some difficulties with the voicemail icon. I want to get this sorted for you.
Voicemail can be accessed by holding the 1 key or dialling 222. My suggestion to remove the icon is to leave a message on the voicemail and to access it via the above methods. Once you've listened to the message delete it and see if this works.
