I'm assuming the "accumulation" report you're getting is on your hotspot device itself and not http://my.t-mobile.com ?
There's probably settings on the hotspot somewhere that tells it what the billing period is and/or to reset the usage at a certain point. That's what your phone does.
I have no way of knowing since the hot-spot has no screen or other options. You can only plug it in and turn it off and on. I don't know that powering it off and on is going to reset anything, since such action has not affect on you smart phone.
Thanks for the suggestion.
My next question will be how to access the hot-spot as an admin from your smart phone. I will do some investigating and see if I can find out.
I did as suggested, I turned the device off and on. It reset the statistics within the device, but it did nothing
for the My-T-mobile usage report. At the bottom of the USAGE report is has a label "End of Month Usage".
To me this means that the report is produced monthly by T-Mobile from their data and the device has no input
on the data being reported.
I guess it is up to T-Mobile to make a change if they are so inclined.
Well, at that say in Russia, "just live with it".
http://my.t-mobile.com reports are generated from T-Mobile.
They do not get input from the devices (think about it -- devices could be rooted and if they relied on the device to send the information and someone removed that piece, they could hypothetically get infinite data).
Devices themselves also have a tracker built in (generally). These reports are generally accessible from the device somehow (with phones, it's in the settings generally -- I'm sure there's a "settings" page on a hotspot... I can get similar on my home ISP's router, I think). These should "generally" match what the provider says you used. There's rounding and sometimes things may not be caught (for whatever reason) on one side or the other (not sure why, but people have seen it. I've noticed my phone's usage says I use more than T-Mobile does -- not much, but it's there)
I did some research. I believe I have ZTE Falcon Z-917 hot spot. It was sold to me at the T-Mobile store.
You can view the user's manual at ZTE FALCON Z-917 START MANUAL Pdf Download.
This is the same screens I see when I log into the hot spot from my browser.
I can not find any way of changing any setting that might apply to the report or resetting of data usage.
Clearly if you look at the user's guide, the Z-917 is not a smart phone. It has very limited customization
capabilities. Which is probably good from T-Mobile and a dumb end-user perspective.
Thanks for your answer.
I did find a "reset" (i.e. disconnect) button. This button (disconnect and connect) does reset the statistics
being display on the first screen. It does not have any impact on the report that I see under My-T- Mobile account, USAGE report. This is for the hot-spot. My USAGE report for my smart phone shows the usage per month. The usage report for the hot spot seems to add each months usage to the previous total.
I guess I am lazy. I would like to see the same reports independent of the type of account.
I can do the calculations, and there is a monthly summary value, that I could hand plot.
But it seems that the two reports could just as easily present the same data in the same way.
No big deal.
