How to replace Koodo's free 2 GB add on?

You will have to call and ask that it be extended if possible. There isn't anything else to do unless you change the plan, change the provider, or both.

I can tell you that they weren't that generous before the pandemic and I'm not sure they'll be too generous now. I had $10 off per month on one account, extra 1 GB on another account. Could not get an extension or any freebie/credit for either account.

For some reason, my free add on is running for another 6 months. Nice. :-)

Maybe the countdown was reset when I changed my plan at some point.
