Unlock Aircard 800S (AC800S-1SZNZS)

Hi All,

I have a Aircard 800S (AC800S-1SZNZS) originally form Spark in New Zealand. I want to unlock this to use on the Telstra network in Australia. How can I get the unloack code?

I have contacted spark and they said to get in contact with Netgear.

Any help would be appreciated.

Cheers
