I had been looking for a fleet tracking system that could be hardwired (and hidden,) and that ran off of cell phone service, for quite some time. I was unable to find any that I liked, until one day I came across OneStepGPS.com, and they were exactly what I had been looking for. They were so easy to install and they keep very accurate detail of where our technicians are going all day. I love how I can map their routes and help provide better time tracking of our service calls. I wish I had found these a year ago, because it would have helped me with a dishonest employee and his falsifying time cards. It has alerts that text us when the vans are drove after hours and on the weekends, and the mobile app is just as wonderful as the website.
