When I last went to Canada in February for 4 days - I had 250 of data (I guess MB) for $24.95. I just checked, lowest price now is 120 for $30. That's quite an increase. I know I can shut off data roaming etc., just don't know how often I'll have access to fast WIFI so I should add it, but it gets a little nuts. Problem is, as I remember for the last time, the phone is on Telus (say), but it keeps looking for an AT&T signal so you fairly burn through data. My phone is locked so I can't get a Canadian Sim for it. Irritating.
