Data usages at weird times?

[QQQQC]

I noticed there are some 12AM or 3AM data usages in my recent usages histories. It doesn't make sense as I am always at home with wifi at night or morning.

Is it the provider running data checks?

It may also be a summary of my daily usage, but if so why there are two entries per day?

PM updates your data usage twice a day. Normally around noon and around midnight so your usage is not real time.
