The race for your mobile data dollars is hotting up. If you don't mind the Optus network that it's hosted on, Virgin Mobile will give new and upgrading customers a total of 12GB of 4G-friendly data per month for $50, with no fine print or finicky eligibility periods.
As long as you're not already on Optus — sorry, guys — you can access Virgin's 8GB of bonus data on its usual 4GB $50 per month plan from today until the end of March. You have to bring your own unlocked phone from another network, or be upgrading your existing Virgin plan. As well as that big lump of data — enough for 400MB per day — you also get unlimited national calls and text and MMS, plus there's also a $300 allowance for international calls or messages and free voicemail access.
If $50 is too much, Virgin also has 6GB total data for $40 a month and 1.1GB for $30. [Virgin Mobile]
