I had 6 days to go till my data refreshes and was at 94% of my 10 GB of data usage so I started turning the modem off except during our early bird free zone, now I noticed it's at 99 %, how can that happen? The modem has been off and it still shows I've used 500 MB's??? Akso, a tecnician told me a site where I can check more detailed usage but lost that site, does anyone know the address so I can see what's going on??? Thanks.
