Our Current Cellular Coverage Area

The sentryGPSid™ personal location device utilizes cellular technology to report it's position back to our webportal. Our GPS devices currently utilize TMobile SIM cards and cellular networks

 

 

Our coverage maps provide high-level estimates of our coverage area when using your device outdoors under optimal conditions. Coverage isn't available everywhere. Estimating wireless coverage and signal strength is not an exact science. These are gaps in coverage within our estimated coverage areas that along with other factors (network problems, software, signal strength, your wireless device structures, buildings, weather, geography topography, etc.), will result in dropped and blocked connections, slower data speeds, or otherwise impact the quality of services. Services that rely on location information depend on your device's ability to acquire satellite signals (often not available indoors) and network coverage. Estimated future coverage subject to change.
