The $19 Optus Cap Plan includes $70 of included value and 100MB of included data, making this plan ideal for light users who make 10-20 calls, send about 20 text messages and need 100MB of data each month. Optus covers 97% of the Australian population with 3G dualband handset, and offers unlimited mobile access to Facebook® and other social networking sites. Customers may need to pay a mobile repayment on 24-month contracts where a handset is included with the plan.
