So, no, GPS does not use cellular data.
So how does it work if it isn’t pulling from your data? Using the signals and satellites, GPS can receive information and relate it to the orbit of the earth. The signals get sent to your device without needing data from your cellular network, which means GPS can be used even if cellular data is turned off or there is no Wi-Fi connection. Once signals are transferred, the GPS knows exactly where you or your device is located on a map. Most GPS applications allow people to download maps for offline use which assists when traveling to locations with poor reception or no service at all.
One example of a time when cellular data might need to be considered is when downloading applications that function with GPS but require data for additional features or services. It is always a good idea to review the fine print before use. If the app is necessary, limiting data or turning it off completely can be used as a workaround. The good news is that normal GPS maps, such as Google Maps and Apple Maps, do not use cellular data.
This means that companies can roll out business applications or software that an employee needs to have on their phone that requires GPS. Employers should not need to reimburse employees or pay a stipend for cellular data. That said, double-checking if additional features are included in the rollout that would require data is always a good idea.
GPS being free is great news since it has become such an integral part of our daily life.
