Hologram's Dashboard allows users on the Professional and Enterprise plans to get location information for their SIMs. To get this information simply go to the SIM in question's page on the dashboard and hit the details link.
The information provided is based on cell tower triangulation, so accuracy varies depending on the SIM's location and tower density in the region. For dense cities the location of the SIM should be within a 1 Kilometer (0.62 Mile) radius. For more accurate location information we suggest using a GPS module.
