I tried to add a data booster, it failed cuz I forgot to add the missing balance before. The money is now all on the account, but the option for the $30 2GB data booster is missing from the drop down menu. I emailed koodo, but the person replying didn't understand.
You can only order the bonus boosters once each. They will then disappear from your list of available options. If this is the first time you are ordering, *611 may be a better bet. The web site can be flaky sometimes depending on which browser you use.
