Telstra may not offer the best value, but you do get what you pay for — the biggest network in Australia, with the best speeds and coverage. Telstra has two options for prepaid wireless broadband: $129 gets you the MF626 USB modem, while $179 gives you the Turbo USB modem, the latter providing up to 7.2Mbps download speeds compared to the MF626's 3.6Mbps. Both include 75MB of data to start, but Telstra will also give you 1GB of bonus data if you activate your new service before 31 December, and will double your data allowance if you recharge $40 or more before the same date. The expiry date for all recharge amounts is 30 days but if you recharge before 30 days, your credit expiry date is re-set to 30 days from the date of recharge. Recharge options are $20 (150MB), $30 (225MB), $40 (300MB), $50 (625MB) and $60 (750MB), $80 (3.5GB) and $100 (6GB).
