Abstract: A method for managing accessibility to a visual voicemail (VVM) service from a mobile device includes detecting that a first SIM has been inserted into a slot interface of the mobile device and establishing a data session with a VVM system to create a first VVM account. The first VVM account is configured to receive and store voicemail messages directed to a subscriber identified by the first SIM. The method further includes the mobile device receiving a voicemail message from the VVM system and storing the voicemail message in a memory. The method further includes the mobile device detecting the first SIM being removed and a second SIM being inserted into the slot interface. Upon insertion of the second SIM, the mobile device prevents access to the voicemail message associated with the first VVM account and communicative access to the first VVM account.

Abstract: A method for operating a mobile device to set a voicemail greeting includes providing the mobile device with a memory for storing a visual voicemail (VVM) application, an I/O interface, and a microphone for receiving an audio input. The method further includes: receiving a selection for an option to record the voicemail greeting, receiving the audio input, recording the audio input as the voicemail greeting for a voicemail account associated with the mobile device, storing the recorded voicemail greeting in the memory, and generating a request that includes the recorded voicemail greeting, a network address for a VVM system, and instructions to set the voicemail greeting as an active voicemail greeting for the voicemail account. The method further includes transmitting the request to the VVM system and receiving a response from the VVM system that includes an indication of whether the voicemail greeting was set as the active voicemail greeting.

Abstract: Methods for provisioning and initializing visual voicemail services on a mobile device, setting or changing a voicemail greeting for visual voicemail service, changing a password for accessing visual voicemail service, setting or changing a recorded name for a visual voicemail service, managing incoming voicemail messages for a visual voicemail system, managing a telephone user interface (TUI) for a visual voicemail system, managing multiple subscriber identify modules on a mobile device configured for visual voicemail service, and secure connections to a visual voicemail system are described herein. Corresponding systems are also described.
