T-Mobile SyncUP Drive. The SyncUp drive has many uses. Plugged into your car, it tracks your trips, warns you of low battery, tells you about recalls, and other handy stuff. But, as this photo shows, it also, when powered on, provides WiFi to you and your passengers within a 30 foot range. Here is my computer at breakfast, connected to the WiFi in my car. I prefer to tether or connect to my Smartphone; but, where there is Internet, there is a way.
