The detail data usage log used to show when data was used on each day, I understand that the actual time might be off a bit depending on when the usage were calculated and reported. But this month when I viewed the report, the log only shows four lines of entry for each day. For example it will show data usage at 2:05 am, then 8:05 am, 2:05 pm and 8:05 pm. Exactly the same for every day of the month. Why is that?
