I never use all my data allowance, but yesterday I ran out a week early so I renewed my £12 4G goodybag. Today I received a text to say I have used 80% of my data allowance, in one day!!! My goodybag renews on 22 September. Has anyone else had this problem? I don't understand it at all, any ideas anyone? I'm scared to turn my data on!
You probably have a few apps that are using your data in the background without you knowing. The best way to find out which apps are using it, go to settings, mobile data and usage to view a which apps used what.
