My Samsung S 4 died after 10 months. Took it to Koodo Kiosk in the mall and was happy that I was able to get a loaner phone. However my data usage shows 190 megs used during the time that I was at the kiosk and another 40 megs later that night that wasn't me. I'm about to go over and don't even have data turned on. Has anyone else experienced any thing similar. About to pull my Sim card.
