Australian online retailer Kogan Mobile has heavily discounted its unlimited plans, revealing $8.95 and $10.95 monthly deals.

Kogan’s 3XL plan now offers 30 days of unlimited standard calls and texts across Australia plus 3GB of data for $8.95. The same plan was previously offered at $29.90 per month.

The 5XL plan comes with 30 days of unlimited standard national calls and texts and 5GB of data for $10.95. In October, 5XL was launched offered at $36.90 per month.

Both deals equate to a 70 percent discount and will be on until 31 March.

Kogan re-entered the mobile network resale market in October, reselling the Vodafone 3G network.

"We have seen thousands of people switch to Kogan Mobile since launching last year,” said Kogan founder and chief executive Ruslan Kogan. “Vodafone has invested billions into their network in recent years, and today’s offer is a part of Kogan Mobile’s push for affordability and accessibility in the mobile market.”
