I got this plan a couple days ago while there was still a free LG GPad IV tablet for signing up for 2 years.
Without the tablet, the plan is month-to-month.
I've been paying around $15/month for prepaid voice-only service, and scrounging for data from open wifi and ShawOpen hotspots. This deal was good enough to move me to post-paid, and get a free/cheap VOIP to cover voice service.
Fido states that this deal is only available to existing post-paid subscribers, but some 3rd-party resellers will give you the deal. I got mine from T-Booth, which is the same company as Wireless Wave. WOW Mobile, the official FIDO store, and Best Buy Mobile would not do it.
