Kogan Mobile cuts 40% off big data 90-day plans

Kogan Mobile is hoping to lure new customers into the fold with a 40% discount on its big data long-expiry plans. 

The telco's 10GB 90-day recharge will set you back $59.90, while a 14GB 90-day recharge has been cut to $80.79. This works out to be $19.90 per 30 days and $26.90 per 30 days, respectively.

With both plans, you allowance resets every 30 days. For example, if you were to sign up for Kogan's 10GB 90-day plan, you'd get have 10GB to use every month for those three months.

This promotion is available to new customers only and runs until August 17.
