I usally don't use mobile data while at home since my phone always connected to Wi-Fi. When I travel to office usually mobile data I use and mobile set to driving mode hence don't use much data. After coming to office I used Wi-Fi again.
Strange morning : When recevied text message I used 80% of data (2.4GB) remaing 600MB left and 9:32 I recieved text saying I have data in goodybag has runout. I didn't use phone/ not opened any apps and some apps may running back ground but same apps in phone same settings never used that much data in short time. Strange when I contacted giff gaff agent they sent me all data I used by dates and gave some suggestions. What I want to know which app in background consumed that data? Is it way to find out? Or How to root cause the issue so that I try to avoid the data being used aggresivley.
Is it iOS I have updated few days ago or Network or apps ? I done quick google search some people from O2 and Vodafone had similar issues but issue not resovled.
Any help much appreaciated. Thanks in advance.
