It is best to wait until your service is active with us specially if you have a homephone number being ported over.. Although I would like to confirm first what type of NBN technology you are having.
Let me check those details first to provide you with a more detailed information. Any chance you can send your Customer ID or username via private message so i can locate your account?
I’ve received the AX5400 modem. If there is an existing NBN connection at the property can I cancel my previous provider and connect the new modem or do I still need to wait for TPG to connect my service?
