T-Mobile Sync Up Drive | Monitor Your Car & Loved Ones via Your Mobile. After our recent auto theft, I have been researching auto security. Since I am a TMobile customer, I was interested in the SyncUp Drive, which connects to most modern cars' OBD readers (On Board Diagnostics). It has its own GPS, so the car can be located with a SmartPhone app. The kicker, for me, is that it also functions as a WiFi Hotspot, for up to 5 devices. It even works in my 12 year old car. TMobile is running a promotion that credits the cost of the device over a two year period, on a monthly basis, effectively making the device a no cost addition. You can get 2 Gigs a month of data for $10, making this a no brainer choice for someone who wants GPS protection along with WiFi access.
