Time with%20data%20but%20no%20num

[Data8]

Hey there guys hope your all safe and well and looking forward to this madness coming to an end.
Can somebody please answer why does my bill have numbers next to who’s been called or texted but then at bottom it has a time network always o2 and then data used, what does this mean if at 4am half a gig is used as said no number what would be the things to record this at these times. Hope makes sense
Cheers
JJ

@Data8 It sounds as if your phone is using your data to update your apps that are running in the background. I don't know what phone you have, but my Android phone is set to update apps over WiFi only.

O2's billing system always updates overnight @Data8 so the data used is not necessarily at the time shown @Data8
