The Virgin Mobile Post-Paid Big Plan 29 includes $250 of value and 250MB of data, making this plan ideal for light users who use their phone every day, make 50-100 calls, send 50 text messages and use around 250MB of data each month. It's a great plan for those who want to bring their own phone with them to a new, good value plan. Virgin mobile uses the Optus network to provide network coverage, which covers 97% of the Australian population.
