The new broadband service features several plan options starting at 40GB per month for $49.95 through to a terrabyte plan for $99.95 per month.
Customers also have the option to bundle their home phone to receive a $10 per month bundled discount.
The service is provided using M2's recently deployed "all-in-one" gateway modem equipped with built-in wireless n. iPrimus is part of M2 Telecommunications (ASX:MTU).
The telco has also connected its first NBN fixed wireless broadband customer in Warrenheip, Victoria.
The new plans offer iPrimus customers with NBN grade bandwidth, which can be a significant increase on what has been traditionally available to these customers.
