Both my wife and I just signed up for Koodo. This will be our 3rd bill cycle. As soon as the billing cycle reset, both my wife and and I reset the data on our iPhones, so it shows that we used 0mb for the 'current period'. When checking the Koodo app and Koodo self serve online, both phones showed that 20mb of data was used. This may not seem like much, but we only have the 100mb data plan on our phones, so losing 20% of our data is killer. We wife went over 100mb last month as well and was billed an extra $5. Could it be possible that 20mb was added last month too right away? Will this occur on future billing cycles, and why?
