The ISP made headlines in January when it announced trials of an unlimited xDSL product.
Trials of the service are ongoing in regional Australia as well as the Sydney and Melbourne metropolitan areas.
Part of the reason for the initial trials, which are due to wrap up in the next fortnight, was to choose a wholesale provider to back the service.
The ISP announced today that Telstra won the agreement "hands down" and that the agreement would push unlimited broadband out to over 1,400 exchanges nationwide.
The ISP's director of ‘stuff', George Kaloudis, said that some trial users had pulled up to 10GB of data per day, but he insisted myKP's business model is sound.
"It's taken us four years to get to this point. We've done a lot of numbers and research and we believe we have the model right," Kaloudis said.
"Once fully operational we believe it will fly but we don't have crystal ball and we may need to make changes here and there to make sure its sustainable."
myKP has previously announced part of its business model is to offer a ‘no frills' service. Multiple IP and email addresses and tech support all incur additional fees.
Kaloudis said the company will also derive advertising-supported revenue from the myKP log-in page.
Advertisements will be targeted at individual subscribers - using information gleaned from asking users their preferences for ads to be served to them, and also by segmenting its own database and selling the resulting demographics to advertisers.
myKP also plans to introduce IPTV, internet radio and music subscription services to increase revenue off the unlimited ADSL2+ plans.
Kaloudis said myKP is currently integrating its systems with Telstra systems. The process is expected to last two months.
He believed Telstra - traditionally strong opponents of unlimited broadband plans - didn't have a problem with myKP's service.
"At this stage it doesn't impose too much on them," he said.
"They get paid whether it's unlimited or not."
