Our NBN plans are sold as a bundle. You are not required to use your phone and you have the option not to plug in a handset if you do not intend to use the home phone. No minimum call spend is required and line rental is already included as part of your bundle service. You may also opt to get a voice add-on.
However, for NBN Extra Fast plans do not include a phone service and are only available on a no lock-in contract.
Let us know if we can be of further assistance.
