Purchased a card in September 2007 specifically for use in New Zealand. Despite trying many pay phones there was not one where it would work for calls within New Zealand. A recording would come on that said the number was invalid but in each case when I went to a tourist center or begged help from someone else the number worked fine.
I could call back from a pay phone to the U. S. but the rate was 6 times the advertised price. I sent 5 emails to firstname.lastname@example.org and did not receive a single response.
