The new subscription have been stopped, and the service will be suspended on 27 March 2018.
In addition to the existing 3G voice mail services, 3HK customers can apply for the iPhone's Visual Voicemail (VVM) and Android Visual Voicemail app (iPhone and Android VVM are not the same service. Please subscribe separately for the VVM for different OS). Visual Voicemail allows you to browse a list of your messages and you can choose which one to listen, reply or delete, just like the email, you can also go directly to any of your messages without listening to the prior messages. You are no longer limited by the voice call flow and you can quickly select the messages that are most important to you.
