The portable internet devices seems to be popular in Asia regions, many tourist rent them when they visit. For those unfamiliar, basically its like a mobile wifi hotspot that the tourist carry around with them (because many place still have no free wifi) and they connect their phone, ipad, laptop, to it. Price varies by the plan, but its maybe $5/day with 1Gb, and you just go rent it and return it the next day to the store.
So where can a tourist pick one up, in downtown Calgary?
