Rogers 4G LTE not a bad deal
On a 3 year contract you pay $350 for the device and then $17 per month for 36 months if you have a shared data plan already on your smartphone.
Even if you bought it outright at $550 with no contract it would still cost you a flat $12 per month just to share the data. Therefore, the incremenatl monthly cost of ownership is really only $5 for 36 months.
That doesn't seem too bad but still begs the question; why get a 4G LTE when you already have a PB and BB Bold to use as a hotspot.
