TPG has announced that it will be launching six-month mobile plans at zero cost for its first customers from Q3 or Q4 this year, with the provider also offering customers access to unlimited data.

The first 1GB of data per day will be provided at 4G speeds, after which it will be capped at 1Mbps speeds for the rest of the day.

After the initial half-year period, customers who choose to stay with TPG's mobile network will then be charged AU$9.99 per month.

"The TPG team has been working hard constructing our own network, and I feel proud and excited to be introducing our very first on-net mobile product offering. We are inviting users to register to experience our coverage and network performance as well as to take advantage of unlimited mobile data for free," TPG executive chair David Teoh said.

"This promotion is the first of its kind in Australia, and signals a new era of competition in the mobile market and will undoubtedly bring great benefit to Australian consumers."

COO Craig Levy said TPG plans to sign up all customers via its website, where it will also provide customer support. The provider last month also rid itself of SIM and MMS fees[1] while still operating as an MVNO on the Vodafone Australia mobile network.
