Yes, I do that. I close all the apps. I shut FB down each time I get out of it, I log it out completely. It just keeps getting worse. Which leads me to believe it's AT&T trying to sell me a bigger data package, because I'm scrimping my usage smaller & smaller and yet every month earlier & earlier they will text me warning me I'm close to using all my data. Then I will really scrunch my usage, would use our WI FI here more here at home. Now the last three months they have told us we are nearly using all our data on it, we have never ever been close to doing that. Last night was the last night before my data renewed on my phone and at 9 PM I got a text saying I had used all my data and they had added more for $10 for me to use by the 24th, TODAY! They charged me $10 for 3 hours, and what of it I don't use they take back???? Not right! I just do not see that all this time, we have not changed our habits any, even cut them down and we are using so much data??? Something seems wrong. I am thinking of reporting them to the FCC
