  • Do you have anything running in the background like a Map app?
  • did you receive an email with a large attachment?
  • did you recently update or download an large app?
  • are you watching any video?

Go onto the Telus Mobility site and have a look at your data usage.  It will indicate at WHAT TIME there was any usage spike.  Then look back at how was the phone used at that time window.
