They are required if you are calling local to where you are though (In this example +1 for US)
Naturally.
And yet the example given, is for an NZ example. Under a broad, how to use when overseas banner. See where I'm coming from?.
My parents/grandparents would still use those instructions. Despite most of those 'in the know', confirming it's not required for local. More understandable if it said 'How to I make non-NZ number calls when I'm overseas?'
