The Virgin Mobile Pre-Paid Simple Recharge 19 includes $50 of credit (90-day expiry) and 1GB of data, making this plan ideal for light users who make 10-20 calls a month, send about 20 text messages and only need around 50MB of data. Virgin mobile uses the Optus network to provide network coverage, which covers 97% of the Australian population. Virgin mobile offers unlimited calls and text Virgin-to-Virgin.
