No, someone cannot track your location solely based on the presence of an eSim card in your device. The eSIM card itself does not have built-in tracking capabilities or GPS functionality. Its primary purpose is to facilitate connectivity to a mobile network.

However, it is important to note that mobile network operators, with whom you have an active eSIM profile, can have access to certain information related to your device's location. This is necessary for providing cellular services, such as routing calls and data to your device. The network operator may collect location data for legitimate purposes like network optimization, emergency services, or to comply with legal requirements.

Additionally, other apps or services installed on your device, such as navigation apps or social media platforms, may request access to your device's location information. If you grant permission, these apps can utilize various location services, including GPS, Wi-Fi, or cellular network data, to determine your location.

To protect your privacy and control access to your location information, it's essential to review and manage the permissions granted to apps and services on your device. You can adjust location settings in your device's settings menu and selectively grant or revoke location access on an app-by-app basis.

In summary, while the presence of an eSIM card alone does not allow someone to track your location, it's important to be aware of the permissions you grant to apps and services that may use location-based functionality.
