This is an award winning wireless mobile deal that runs on the OPTUS network. The only other network that has higher coverage is Telstra. Their wireless modem is $299 and for 7GB you have to pay $40 monthly for a 24month plan.
So for 3 months off, plus free modem, and $5 off monthly if you have virgin mobile as well, this is a great deal!
You just described how bad telstra is in comparison and left out all the details for this deal.
This cap costs $39/month and you get 8GB/month.
With telstra, you get a $299 rebate on the modem, if you're on the 24 month contract.
