The very moment I add a new 1GB data booster to my prepaid plan, the usage updates to show: 5.293 / 1024 MB Used. Where does this 5.293MB of "instant" usage come from and am I being short changed (it seems so!).
It comes from the fact smartphones use data on a constant basis, even if you aren't using your phone. When your phone didn't have data, your apps and phone were still trying to use data but were blocked. As soon as you added the data booster, the data "block" was unblocked and the apps/operating system could start using data. It's legitimate data usage
It happens within milli-seconds (as soon as the koodo page refreshes it shows this amount) then stays at that number until the phone is actually used. Also seems consistent as this is the 4th or 5th time I've observed it. Next time I will turn off data on the phone before hand when I add the booster and see what happens.
