Welcome to the community!
We're able to locate your account using your Community Details. The NBN service that we offer is sold as a bundle plan which includes the home phone service. 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.
Let us know should you require further assistance.
