The USA company AT&T uses roll over data. This means that the data you do not use in this month can be used in the next month. Since I'm guessing koodo will never release unlimited data plans I think that roll over data would be a valid solution to those data hungry people!
Monthly subscribers should get roll over data...some months in use more, some months in on WiFi more...it depends if I'm travelling or not, we pay for it..why should it expire at the end of the month? Comes down to profits..Koodo feels like it will lose money...the funny thing is, if they did implement roll over data they would get a lot more new customers switching over as no other cell provider has it....dont believe me Koodo??? just try it for a year and u will see.
