Visual Voicemail

With Visual Voicemail (VVM), your COMBOX® missed calls messages are displayed directly on your smartphone. You can listen to them there and then, without calling the COMBOX® number.

VVM is supported for iPhones and Android devices from Android M onwards. Ensure that the most recent update is installed on your smartphone.

The function is activated as standard on Android devices. The function needs to be activated before the first use on iPhones.

Activating VVM on iPhones:

    1. In device settings, switch on mobile data.
    2. Text ‘STATUS VVM’ to 444.
    3. You will receive an order confirmation by SMS.
    4. You will receive a further SMS if VVM has been successfully activated.
    5. Switch the device off and back on again after a few seconds.
    6. Go to ‘Telephone and Voicemail’ to finish setting up VVM on your device.

Note: VVM requires mobile data. Charges may be incurred if data roaming is activated.

A flashing light and/or symbol (envelope symbol, cassette symbol, '1 message’ or similar) indicates the new message on the display. MWI replaces the previous notification system, where COMBOX® called you when a new message was received. The previous notification system remains active for Smart Business Connect and Managed Business Communication customers.
