Done it, the deal was too good to resist: my spare mobile phone plan was sitting at $10.05 on the pay-as-you-go prepaid rate, when data is used, it's charged at 5c per MB ($51.20 per GB) and is meant for very casual usage. But I'll need more and in just under 40 hours, the deadline for the carrier's special 1-year Super Pack ends.
The deal is available for existing customers who recharge online before 5pm on Friday. It costs $249, includes all the national calls & SMS plus a very generous 42 GB of data: that equates to 3.5 GB per month for a shade over $20 per month.
