I have the $25 dollar plan Canada-Wide Talk + Text 25 Dbl and last month I activated my data because I wanted to send mms, but would close it after, so I wouldn't be charged with data. But I just got my month's bill and it added the charge, why?
You probably used the tiniest amount of data, Diana, and the first tier is $5. If you have no interest in data whatsoever, you might want to call Koodo and ask them nicely if they will refund you for once... I know they are usually very lenient if you explain what happened :)
Make sure you are on WiFi when you enable data... it's a pain I know and most of us would like to see a slightly larger margin for data without being billed for it!
