Optus is currently running a special offer of a USB modem and 1GB of data for $99, provided you purchase and activate the service online (otherwise you get 200MB). Like Telstra, all Optus data has a 30-day expiry and unfortunately is counted in 10MB increments, including uploads and downloads. Optus does roll over up to 10GB of unused data if you recharge within 14, 29, 59 or 185 days, depending on the value and expiry of your last recharge. Optus also has a maximum data allowance at any time of 10GB. Recharge options vary with $15 (500MB) and $20 (650MB) recharges lasting 15 days, $30 (1GB), $40 (2GB) and $50 (3GB) recharges lasting 30 days, and $70 (4GB) and $100 (6GB) recharges lasting 60 days. Optus also offers long-life recharges that last up to 186 days — $80 (4GB) and $130 (8GB).
