OMG!!!! that is why I switched from Koodo to PC mobile because of the trouble I was having with Koodo. When I was with Koodo I was being charged for data usage when I always, always, always had my data switched off so I wouldn't haven't these mysterious data charges. I called Koodo, never got a satisfactory answer as to why this was happening so I switch to PC. and have not had these problems since with PC. All I can say is, I better not have the same problem with Koodo again!!!!!!!!!!!
