Hi @Robodent ,
TPG defines a Local Call as a call made to a number in the same standard zone units that are geographical boundaries determined by the Australian Communications and Media Authority. It is possible that a call made within the same state or the same area code is not considered as a local call. We do not expect you to always know what is considered as a local call. Please visit our online call rate calculator on https://www.tpg.com.au/homephone/calculator before calling to check whether a call is considered as a local call.
A National Call (Interstate) is when you call a landline number that is not in the same or adjoining Standard Zone Unit.
Let us know should you require further assistance.
What (if any) is the difference between Standard National Calls and National STD calls ? This is unclear in TPGs' critical information documents.
