I bought my iPhone 5s from Koodo on Friday and it's telling me that I've already used 95% of my data. I shut it off immediately but don't understand how I already could have used 500 mgb in just two days. I don't use my Apps, email, Facebook, etc. that excessively that it should already be almost used. I'm concerned because I don't want to go over, but for the amount of time I use it, the lady at the Koodo store thought I would be totally fine with 500 mgb per month. Please help!
