Phone geolocation is now built into most smartphones. It allows you to find your location, share your position, locate a lost device, or even reassure a loved one.

Some solutions take the form of simple native settings, while others use a geolocation application or a specialized mobile app . But how does phone location actually work? What tools are available? And what does the law say in France?

How can you find out where someone is using their phone?

To find out where someone is using their phone, several technologies are used simultaneously. Smartphones combine different geolocation methods to obtain the most accurate position possible.

GPS (Global Positioning System)

GPS is the most accurate method. It works using satellites that send signals to the phone. By cross-referencing the data, the device calculates its position.
Accuracy: Approximately 5 to 10 meters outdoors.
Limitation: less effective indoors.
This technology is also used in some GPS trackers and dedicated devices such as a GPS watch for children.

Wi-Fi

Even without GPS enabled, a phone can be located using nearby Wi-Fi networks.
Accuracy: Good in cities and indoors.
Limitation: depends on the density of available networks.

Triangulation of mobile antennas and networks

The phone can also be located using the mobile network's relay antennas.
Accuracy: variable, sometimes by tens or hundreds of meters.
Advantage: works even without GPS enabled.
This method is also used by some standalone GPS trackers .

Bluetooth

Bluetooth enables short-range location tracking, particularly via connected objects or GPS trackers .
Accuracy: very good at short range.
Limitation: only useful within a limited perimeter.

In practice, phone geolocation combines GPS, Wi-Fi, and mobile networks to improve the reliability of the displayed location.

Geolocation tools and services

Many applications use phone geolocation to offer convenient services.

Among the most popular:

  • Google Maps (navigation and location sharing)
  • WhatsApp (temporary sharing)
  • Google Find My Device
  • theFind My app
  • SmartThings Find (Samsung)
  • solutions such as Find My Kids
  • different location-based applications specialized

These services function as a tracking app when location sharing is enabled by the user.

Some families also use a parental control app that includes real-time location tracking. This type of tool often combines geolocation with application managementto supervise phone use.

How can I locate a cell phone using another cell phone?

It is possible to locate a cell phone using another cell phone, provided that the person concerned has given their consent.

There are several solutions:

  1. Real-time location sharing
    On Google Maps or WhatsApp, users can share their location for a set period of time.
  2. Services integrated into systems
    On Android, Google FindMyDevice allows you to locate a device connected to your Google account.
    On iPhone, theFind My app app allows you to check the location of a device or an authorized family member.
  3. Specialized applications
    Some platforms, such as Find My Kids, function as a parental control application, combining location tracking and safety settings.

In all cases, the device must be turned on, connected to the Internet, and location services enabled.

How can you locate your child or teenager's phone with Neow Kids?

In a family setting, geolocation can support a child's independence, particularly when traveling to and from school.

Cell phone models phone models for teens offered by Neow Kids are compatible with a parental control app such as Google Family Link. Parents can check the phone's location from their dedicated interface.

This parental control application also allows you to:

  • limiting screen time,
  • application management of installed applications installed,
  • validation of downloads,
  • and location tracking.

Unlike simple GPS trackers, the smartphone remains a comprehensive tool, configured within a secure framework.

For certain uses, a smartwatch for teens with a GPS watch can also be a useful addition to their equipment.

The goal is not constant monitoring, but rather gradual support, combining parental control, education, and trust.

Legal aspects, confidentiality, and precautions

Phone geolocation involves sensitive personal data.

Consent required

In France, geolocating a person without their consent may constitute an invasion of privacy. The use of a parental control application must therefore remain proportionate and explained to the child.

Risks to privacy

Geolocation carries several risks:

  • excessive data collection,
  • account hacking,
  • location spoofing,
  • dependence on tracking tools.

A serious parental control application must include enhanced security settings.

Legality of geolocation without consent

Article 226-15 of the French Penal Code specifically regulates violations of privacy related to communications. Locating an adult without their consent may result in criminal penalties.

GPS GPS trackers installed without consent may also be considered illegal.

 

Phone geolocation is therefore a powerful tool, whether it is a simple location appor a parental control app , or devices such as GPS trackers.

Used transparently and judiciously, it can provide security without infringing on privacy. 💙
