Plug in and Go. No Hassle.

The CellAssist App connects to your car through the INsiderTM, a small device that plugs into your car's OBD-II port. Don't think your car has this? If it's a 1996 or newer, we guarantee it does. Take a look under your dashboard for the port. All you need to do is plug it in!
