While there are just four mobile phone network operators in Australia (you all know about Telstra, Optus and Vodafone, but Pivotel is there as well in remote areas), there are stacks of MVNOs who sell services on top of the networks built by the other operators.

Moose Mobile is one of those MVNOs. And it has just signed a five-year deal to resell Optus' 4G services on top of their business selling refurbished handsets.
