Figured that would give a follow up just in case someone down the road is in a similar situation...I went ahead n opted to get the 50MB plan for $30 just so that I would have data if I needed it. Through occasional Facebook/Twitter/Foursquare,Google Maps, Uploading a few pictures here, and using Yelp and other apps, I got by fine. I just avoided checking my email and browsing the full-on graphics intensive web. Free WiFi does appear to be fairly common: the Quays are one giant WiFi zone, and many places around town had free WiFi through the Īle Sans Fil network.
Essentially, it was pretty easy to feed my addiction to always at my side data access in Montreal.
