A device receives, from a user device, a request to use a visual voicemail (VVM) application, directs the user device to a self provisioning server based on the request, and receives, from the self provisioning server, a selected VVM subscription plan and information associated with a user of the user device. The device also provides, to a billing system, a feature code associated with the selected VVM subscription plan, receives, from one or more voicemail servers, pre-existing voicemail messages associated with the user, and provides, to the user device, the pre-existing voicemail messages. |
