This is the first month since I got a Nexus 4 at Koodo. I went with the $29 plan. I am not a data user, and I have WIFI connection at home and at work. I noticed that I am charged $5 for data usage, and I have no idea of why it happened. I now turned off the mobile data option on my phone, does anyone know if this can help me not be charged for data usage again?
