I was passing through Vancouver and needed data to access Moovit (two thumbs WAY up for that app) and over the course of two hours, I used 49 Mb of data for almost $15 in charges. That's a big chunk of my bill. It won't be a regular occurence but I was still a bit surprised. My current bill is projected to be $40, so that $15 really pushed it up. Is there a way to know what the cost will be or to go for a lower rate if that is acceptable? I wasn't streaming a movie so I didn't need speed.
On a related note, voice calling didn't work. On reflection I probably needed to add the country code (/facepalm) but I guess I expected that would happen automagically. Considering those data charges, perhaps it's just as well I waited.
