This depends on the access technology deployed in your premises. If the NBN Co needs to install certain connection devices on the interior of your house, you will need to be at home when this happens. The appointment with the installer can be arranged for you by MyNetFone Business, or the RSP of your choice, at a time that suits. However if you are unable to be there for the appointment you will be able to reschedule or nominate a person over 18 years to make decisions on your behalf.
