Dear Community,
The Windows Mobile 7.5 update (Mango) provides a number of improvements to the customers. Unfortunately voice mails aren’t shown visually or audible after the update, as long as the notification SMS is still in the inbox. Windows is going to fix this issue with their next update in December. As a workaround to not miss any COMBOX® message, the notification SMS can be deleted immediately after receiving.
Kind Regards,
