I have an iPhone 6s and have a 1GB booster add-on to my cell phone plan. It says I've used "1023.506 / 1024 MB" on Prepaid self-serve. On my iPhone's data usage tracking (which has been on ever since I've gotten my plan), it says I've used 973MB. Why is the data counter on my Koodo plan inaccurate (and thus costing me extra money)?
I have attached two photos. One photo is of the "Cellular Data Usage" for the "Current Period", and the photo after that is when the "Current Period" started (it is the same day my plan started).
