The main thing to remember
  • Smartphones combine GPS, Wi-Fi and mobile networks to provide ultra-precise geolocation.
  • Tools like Google Maps or Google FindMyDevice allow sharing and locating devices with mutual agreement.
  • French law requires consent to locate a person; the family framework is based on educational support.
  • The first NEOW secure smartphone integrates with Family Link parental controls to promote progressive autonomy and digital well-being.

Telephone geolocation is now integrated into the majority of smartphones. It allows you to find your way, share your location, find a lost device or even reassure a loved one.

Some solutions take the form of a simple native configuration, others go through a geolocation application or a mobile app specialized. But how does tracking a phone actually work? What tools exist? And what does the law say in France?

How do you know where someone is with their phone?

To know where a person is with their phone, several technologies are used simultaneously. Smartphones combine different geolocation methods in order to obtain the most precise position possible.

GPS (Global Positioning System)

The 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: about 5 to 10 meters outdoors.
Limit: less efficient indoors.
This technology is also used in some GPS trackers and in dedicated devices such as connected watch.

Things to remember about GPS accuracy

The system GPS standard guarantees an accuracy of approximately 5 to 10 meters in an open environment. However, buildings, tunnels, or dense forests can alter this accuracy, requiring assistance from other networks.

Wi-Fi

Even without GPS active, a phone can be located using networks Wi-Fi nearby.
Accuracy: good in town and indoors.
Limit: depends on the density of available networks.

Triangulation of mobile antennas and networks

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

Bluetooth

Bluetooth allows short-distance localization, notably via connected objects or devices. GPS trackers proximity.
Accuracy: very good at close range.
Limit: useful only in a restricted area.

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

Technology Average accuracy Main strengths and limitations
GPS 5 to 10 meters Excellent outdoors, but signal often blocked inside buildings.
Wi-Fi networks 10 to 30 meters Very effective in urban and indoor environments, but depends on nearby boxes.
Cell triangulation 50 to +500 meters Overall reach across the entire territory, even without data, but low precision.
Bluetooth Less than 10 meters Ideal for immediate proximity (lost objects), very limited range.

Geolocation tools and services

Many applications use the phone's geolocation to offer convenient services.

Among the most popular:

  • Google Maps (navigation and location sharing)
  • WhatsApp (temporary sharing)
  • Google FindMyDevice
  • The app Locate from Apple
  • SmartThings Find (Samsung)
  • Solutions like Find My Kids
  • Different location apps specialized

These services operate as a tracing app when location sharing is enabled by the user.

Some families also use a parental control app integrating real-time location. This type of tool often combines geolocation and application management, in order to regulate the use of the telephone.

How to locate a cell phone with another cell phone?

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

Several solutions exist:

  1. Real-time location sharing
    On Google Maps or WhatsApp, a user can share their location for a specific period of time.
  2. Services integrated into systems
    On Android, Google FindMyDevice allows you to find a device connected to the Google account.
    On iPhone, the application Locate allows you to consult the position of a device or an authorized relative.
  3. Specialized applications
    Some platforms like Find My Kids function as a parental control app, combining location and security settings.

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

How to locate your teenager's smartphone with NEOW Kids?

In a family context, geolocation can support a teenager's autonomy, particularly during school trips.

The models of first secure smartphone offered by NEOW Kids are compatible with a parental control app like Google Family Link. Parents can consult the position of the phone from their dedicated interface with complete parental peace of mind.

This parental control app also allows:

  • Limiting screen time,
  • The application management installed,
  • Validation of downloads from the secure blind,
  • And location tracking.

Unlike simple GPS trackers, the smartphone remains a complete tool, configured in a controlled digital framework.

For certain uses, a connected watch for teenagers integrating a GPS can also complete the equipment.

The objective is not permanent surveillance, but progressive autonomy, combining flexible parental control, pedagogy and confidence.

Technical glossary

Google Family Link : Service allowing you to configure flexible parental controls on Android devices, offering screen time management, applications and secure geolocation.

Secure store : Application download environment (such as the NEOW Store) filtering unsuitable content in order to maintain a controlled digital framework.

Google FindMyDevice : Native Android functionality allowing you to ring, lock or locate a lost device on a map.

Legal aspects, confidentiality and precautions

Phone geolocation involves sensitive personal data.

Consent required

In France, the geolocation of a person without their consent can constitute an invasion of privacy. The use of a parental control app must therefore remain proportionate and explained to the adolescent to respect their digital well-being.

Privacy risks

Geolocation involves several risks:

  • Excessive data collection,
  • Account hacking,
  • Location theft,
  • Dependence on tracking tools.

A parental control app serious must integrate reinforced security parameters to maintain a secure environment.

Legality of geolocation without consent

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

The GPS trackers installed without consent are also likely to be considered illegal.

Geolocation by telephone is therefore a powerful tool, whether it is a simple location app, of a parental control app or devices such as GPS trackers.

Used with transparency and balance, it promotes parental serenity without encroaching on private life.

FREQUENTLY ASKED QUESTIONS

Does geolocation work without Internet access?
Yes and no. The GPS chip in a smartphone can technically pick up satellite signals without a network connection. However, to display a map (like Google Maps) or to transmit the location to a third party or a parental control application, an Internet connection (Wi-Fi or mobile data) is essential.
Is it legal to geolocate your teenager's smartphone?
Yes, as a legal representative, a parent has the right to use geolocation tools on the smartphone of their minor adolescent. However, the CNIL strongly recommends that this be part of an educational support approach: the adolescent must be informed of this to establish a climate of trust and promote their progressive autonomy.
How to temporarily disable location on NEOW Kids?
On the NEOW Kids device, global location settings depend on the rules set via the management application (such as Google Family Link). Parents can adjust global or per-app location permissions from their own dashboard, ensuring flexible parental control.
