Last night I purchased a 1gb mobile Internet top up from my account credit having run out on my monthly limit. I awoke the next morning to find it fully depleted overnight while my phone was not in use.
My phone is set not to update/backup unless connected to WiFi at home. I have also checked my Web and YouTube history to see where the data usage occurred but with no explanation.
The phone was still connected to the charger this morning and in my possession all night.
I just can't see how 48 months can say I have used 1 gb in less than 8 hours.
How does 48 months explain this?
