Best bet is to contact Swift... We just left there and they use Qualcomm in their trucks. Now that we left and are going out on our own we went with QualComm. They showed us the 'back office' and that software pin pointed our truck in our driveway!! Less than 10' from where it was actually parked... People might not be in the truck, but they can FIND that truck!
yep, had trailer security blow up my phone one morning because I parked across the street from my house for a few hours since it was in route
