I am currently on the prepaid $15 plan, and have been for the past year. Recently I happened to go on the Koodo website, and noticed that the $15 plans have 250 MB of data included (not much, but useful in a pinch). However, when I tried to start using data, it would not work.
Looking into further, I realised that the data must not have been included when I first signed up. The plan price and all other details were the same, just a bit of data was added.
It looks like my best option now is to change my base plan online. Currently, I'm waiting for the end of my billing cycle, so that I don't have to pay to renew my plan twice within a short amount of time.
Could this change not be done automatically as a customer service to existing customers?
