I was in Harvey Norman @ Domayne in Alexandria today and saw three BLINK USB 3G modems in a bargain bin. The marked price was $99 but they are currently running a promotion: -
The modem is free if you sign up for 1 month internet access with BLINK. The rates I was told were
1 GIG - $35
3 GIG - $45
6 GIG - $75
There is no contract, it is month to month with two business days notice.
BLINK is also running a promotion that expires at the end of the year which doubles the normal 3 GIG limit on the $45 plan to 6 gig for the first three months.
Blink uses the 'yes' Optus network. I don't know if the modem is locked or if you could crack it to work with other networks, however since I am moving house and need internet access for about a month, this was perfect timing and a very good deal.
do you know the model of the modem ?
