This is my first month Koodo and everything is so far so good. However, I find changing plan is little uncomfortable in terms of billing. I don't like my monthly cycle/usage being prorated. Not only make the following bill not normal(which I can bear) but also might generate overage charges. Therefore, ones have to check their usage before changing plans. I think plan change should be easy and worry-free( of these overage charges) According to (http://help.koodomobile.com/my-bill/charges-explained/what-happens-when-i-make-changes-to-my-account
), it didn't mention what would happen if plan change is made EXACTLY on the Bill Start Date. Would that avoid being prorated? My bill date is 16th, so bill start date is 17th. If it works, should I make plan change on the 16 or 17? Does it matter when to make change of that day? Also, I heard that customer centre can make plan change pending for new monthly cycle. I wonder if Koodo could add that option for plan change in Self Serve. Thank you very much.
