My mobile signal drops out and then as soon as it reconnects, I get a voicemail notification saying that I have a voice mail, when I call I'm told that there is no new mail. This is very frustrating.
Can you try dialling your voicemail, then select Option 3 for settings and features and then option 2 to manage your message alerts. Turned off message alerts by selecting option 1 and let us know if this helps at all in resolving this.
