Just noticed that Optus has double data bonus on their prepaid mobile broadband.
Previously $130 recharge got you 22GB to use in 2 years.
Now you get 44GB.
Great for those who are after long expiry for use in a tablet or as a backup connection.
$30 - 8GB - 1 month expiry
$50 - 14GB - 1 year expiry
$130 - 44GB - 2 year expiry
