The "rules" for legacy plans are .... different.
7000s daily plans are different from 9000 daily systems. 7000s users in Alaska have the rules applied different.
9000 daily plans are thus:
All times are "local"
Plans have a "roll-over" feature where up to 2 days of allowance can accumulate (IE; 525 MB per day refill with "data bank" would equal a max Anytime value of 1050 MB)
The "Anytime" data bucket is from 7am to 2am local
The "Unlimited data bucket" is from 2am to 7am local.
The new "daily allowance" is add to your data bucket at 5am ... but you will not begin to draw from that data bucket until 7am.
Because of the data bank feature the new daily addition will only add your "daily allotment" that is added to the previous days remainder as of 2am.
Example: You don't use your computer for two days ... day 1, 525 MB is added and you use none so at the end of Day 1 you have 525 "in the bank" at 2am. At 5am the day 2 allotment is added to your remainder ... added at 5am. You will see the total amount in your Anytime Bucket. You just won't draw from it until 7am.
If you had less than your full daily allownce left at 2am, that lesser amount is "banked" and the next day allowance is added at 5am. Lets say you had 250 MB left at 2am and 525MB was added at 5am for a total of 775 MB available to be used starting at 7am when the unlimited free zone ends. It may be that the lower "roll-over" amount is what is making it appear you are using data earlier than 7am.
This is said by someone who had a 7000s system for years that had even more complex rules for those few of us that had data bank on that system
.
Screenshots are your friend here:
Take one before 5am ... that will document your roll-over amount.
Take another just after 5am when your daily allotment is added to your previous days remainder
Take a third screenshot just prior to 7am .... your Anytime data should not have dropped ... meaning you were drawing from the free-zone prior to 7am.
EDIT:
Just clarify ...
9000 Daily plans .... Anytime Bytes: 7am to 2am, Unlmited Free Zone 2am to 7am local time
9000 Monthly plans ... Anytime Bytes: 8am to 2am, Bonus Bytes 2am to 8am local time
Just because your remaining data is increased at 5am is no reason to think that you are "using" from it .... unless you see those numbers drop before 7am.
