Data usage on a S3

[clayton123]

Good day every one I'm in a battle with my service provider MTN my data usage on my phone is about average 355MB from the beginning of the month to date.
But according to my bill I have used over a gig something is using my data and my service provider is unable to tell me.
I have check updates on apps and its not the case....

Your screen shot only shows the current period. Tap on the data cycle to see an earlier one. I would also recommend that you reset the data usage cycle to match your billing cycle so you are not comparing apples and oranges.

Agreed, My data app that I use is set to show me the month as it relates to my billing cycle. That being said AT&T is showing 186MB and my app is showing 153 MB ~ 18% difference.
