My data usage on my iPhone 6 shows anywhere from 1-12 megs while I'm sleeping. I have wifi connectivity in my house and this usage is eating all of my booster data. I have all push notifications turned off, I have the setting to use data when wifi signal is weak disabled. I am not going to change my phone to airplane mode every night. This is a koodo issue based on the forum. What is it and why is it at the same time every night ( just after midnight)?
