How reliable is a Guardian Angel cell phone?
Very reliable! Guardian Angel Technology went to great lengths to make its GPS devices as reliable as possible. There simply is no device on the market that is as accurate as ours, or takes location readings as frequently as ours. The server that receives data from the GPS units and the database that stores the information are both protected by fail safe backup. Those machines are completely separate from the server that presents location data to the user. Therefore, in the rare event that the tracking site is unavailable, we will still be collecting information from our GPS Device or cell phones.
