You can get that with prepaid. Postpaid is a bit of a different story. There are smaller data add-on options but I don't think that's something for the pay per use data plan

@Ruby711 You can get data add-ons of course. With our shock-free-data plan we send notification of your data usage. When you are close to your limit, you may get a variety of options to add more data. The below is just an example:

When you use up all you hade we pause your date and another option pops up to purchase more.  We believe this gives users greater control and flexibility. I hope this helps. 

That's not exactly what I meant. I was inquiring about a data add-on as opposed to an ongoing data plan. I know some other service providers I've been with offered small data options you could pay to have attached to your plan for a month. I don't see any such options available when I look through the Koodo Add-ons. I'm not using a data plan to start with so that may be why I don't have access to a data add-on, because Koodo is trying to promote an ongoing plan. 

You really should be on Prepaid. There is no point on being postpaid if you don't have data.

I still have a "tab" balance.

That makes sense.
