Optus is the phone network of choice for 18-year-olds who think they can sing heavy metal as they sit on the beach doing nothing in mid-winter for that perfect indie look. To them, Telstra, is too mainstream. Or iPrimus, or iinet, or whatever else life throws at you. They have free WiFi in all their stores, and advertise using a weird-looking cartoon duck. Because a duck really says, 'Buy the new $35 Cap Plan!'.
Articles about Spark NZ, 2° Mobile, Telstra, TransAct, Internode, etc. etc., will come soon.
