My plan expires in a month and I found this when googling.
60GB Data for $89 and 120GB Data for $109.
Used online chat to talk to a Catch agent, apparently, there is no Catch for the expiry.
As long as I activate within 24 months, I am good.
I am unable to post a link to Finder being an L plater.

Best of luck, but it could get declined as the URL has affiliate details in it.
