I've been buying my phones unlocked for a few years now, and truth be told outside of international travel there just isn't that much advantage to having an unlocked phone in Canada.
The fantasy of "taking advantage of competitive offers in the marketplace." doesn't really net out when Robellus keeps their prices
within $5 of each other in any given region.
I still have high hopes for Freedom mobile, but it doesn't seem like they have the infrastructure to compete with the national carriers just yet. Yes they are cheaper per month, but it comes at the cost of service/coverage areas.
