Hope this helps. It works very well for me. I used it in the Dallas Airport yesterday for a couple of hours and it worked great. Even though Dalls offers T-Mobile WiFi, I have used it before and at $9.95 for a day when I only needed it for a couple of hours, I decided to try my 8700c as a modem. It was almost as fast as the WiFi I have gotten there in the past and I saved $9.95.
