I just "upgraded" to a new MiFi card and my usage suddenly went up 5 times what it was before. I have not changed anything I do but the meter has gone crazy. I have called tech support and they say that there is nothing unsual about this. I have the 5GB plan and according to Verizon I used 2100 MB in three days. At that rate I will use 21,000 MB in a month. I can't even count how much money that wil be. Verizon is starting to act like the only game in town and has little regaurd for their customer's problems.
Do you have a password set up on your device? I suggest if not, to add a password so no one else can use your connection. To add a password to your connection follow the directions below.
Available on the Security sub-menu ,the Password screen allows you to change the password which you used to login to this Web-based interface.
