T-Mobile has unveiled its T-Mobile SyncUP DRIVE, an all-in-one connected car solution that transforms a car into a rolling wi-fi hotspot and gives added vehicle diagnostics, safety and security features. T-Mobile SyncUP DRIVE plugs in to the car’s OBD-II (on-board diagnostics) port, standard on most cars built after 1996, is always on, doesn’t require charging and can be managed from a smartphone.
