Very high mobile data usage reported by carrier, no evidence in phone My phone is a galaxy Note II, I found out yesterday that I breached the 5 GB limit of data usage for the month when the carrier completely cut my data connections.
I went to check the reported usage in the system settings and it just shows 687 MB used for the month, the highest usage app is facebook with just a little over 100 MB used.

Now here's some facts:


Running Ditto Note 3 v 3.2 (android 4.3) (based on XXUEMK9) (Baseband: N7100XXUEMJ9)
Never used tethering this month
I always keep 3G off at night and when I'm on WIFI


How do I find out what could have caused all this data usage?
The detailed connections report from the carrier will come in 2 months so I can't know anything yet from that, I'd like to try and figure out something now.

I will be getting a data plan upgrade that will allow me 500 more MB for the month but I'm afraid that if I don't do something fast I might end up wasting all the data again, for now I'm planning of clean flashing the newest release of the rom but I'd like to know if there is some app that will let me monitor data usage in a more detailed way as it seems the built-in android graph doesn't record this hidden data that was used.
Turns out it was the carrier that messed up something as it seems I wasn't the only one to get this issue, so I didn't really use all that data.
