Track location by cell phone number. Location by phone number online. How to use operators to find out where a person is

How to find a lost phone and how to prevent it from being stolen - working methods. Information about fraudulent resources that supposedly help you find lost handsets. You can't use them, but some people don't know about it.

To successfully locate your lost phone in the future, turn on Find My Device. Go to “Settings – Security and location” or “Google – Security”, select “Find device”. Activate the items “Remote device search” and “Remote lock and reset”. On some phones, the function is enabled with one tick.

Determining the location of the smartphone

To find your missing phone, go here and click on the device. On the next page, enter your password Google account. After a second, the smartphone management page will open. Select one of the following:

  • Find – the current location of the device will be displayed on the map.
  • Ring – turns on the sound signal. The function will make it easier to find a smartphone at home or in the office - when you have lost your phone and cannot find it.
  • Phone lock - set a password to unlock and a message for whoever finds it. Unlocking is possible only with a password.
  • Log out of your account on your phone to prevent access to your account. Does not affect search functions.
  • Contact your operator to block your SIM card and set up call forwarding.
  • Delete all data from the device - use when storing confidential information on your smartphone. Further searches will become impossible.

Be sure to activate the “Find My Device” function after purchasing a smartphone - this method only works if it is enabled.

If your phone is turned off, you won't be able to find it.

For a successful search, the phone you are looking for must be connected to the Internet. Do not forget to activate coordinate determination at least via the cellular network (turning on GPS can quickly drain the battery).

Lock your smartphone while searching - this will prevent access to data.

Mobile application for searching “Find my device” from Google To use the application, activate the Find My Device function using the instructions above. Download it from, install on another smartphone or tablet. Launch the application, log in with your Google account. After a couple of seconds, a piece of map with the exact location of the phone will appear on the screen - go searching. Turn on the call through the application or lock the handset to prevent data theft.

Phone search services by subscriber number and IMEI

Let's look at working and non-working ways to find a lost phone. Some of the above services are fraudulent.

SNDeep.Info

This portal is not suitable for finding a lost phone. It is informational:

  • Shows the smartphone model by IMEI;
  • Shows the status - stolen or lost (if the handset was stolen, enter its IMEI in the form and add a list of lost or stolen);
  • It may show a discrepancy between the smartphone and its IMEI number (if it has been reflashed).

It does not show the location of the device.

The creators of the service claim that they can find a lost device by phone number. It doesn't actually work - mobile operators do not transfer location data to third parties and services. The service is fraudulent, it was created to profit from gullible users.

We conducted an experiment - we used the service despite Yandex’s warning. Entered the number of the switched off this moment telephone set. The system showed the connection was established and correctly displayed the region - this is publicly available information. The city was determined - erroneously, during the experiment the tube was in another city. Wi-Fi was detected to be turned on - erroneously, since this is a simple phone. A few seconds later, the service allegedly identified the location, demanding registration and money. PLNET is not looking for anything - which is what needed to be proven.

There are plenty of such services - they only show the operator and regional affiliation (this is open data). They will not be able to determine the location.

OM-TEL

Another service similar to PLNET. It doesn't work, don't experiment. More precisely, it works - after registering with a phone number, money disappears from the account. PLNET works in a similar way. Remember, services that search for phones using a SIM card IMEI number and other parameters do not work.

Other ways to find a phone at home and on the street

The easiest way to find a lost handset yourself is to return to the place where the loss was discovered. It may have fallen out of your pocket and into the grass. Look for it on your desktop, look in your desk drawers, visit your colleague’s office. If she's lost at home, use Google's Find My Device service. Activate the call and you will hear where the lost handset is. Use the same method when searching for a phone on the street - it will identify the intruder.

How to prevent your smartphone from being stolen

Keep your smartphone in your inner clothing pockets – it’s impossible to get into them. Anti-theft backpacks provide good protection against theft. When holding the tube in your work bag, hold your hand over it - this will help you feel that someone is trying to get into it. Do not leave your smartphone in visible places, including on your office desk or cafe table. Also take preventive measures - install software for remote blocking and search.

Cerberus

The application will help you find a lost phone that is disconnected from the Internet. Management is carried out online and via SMS. If the attacker installs a different SIM card, the application will report the new number. There is a function remote activation GPS SMS command – turn it on, get the exact coordinates of the handset.

Other application features:

  • Keeps a log of incoming and outgoing calls.
  • Records sound from a microphone.
  • Gives a loud signal on command - will help you find your phone in a crowd of people.
  • Tracks your smartphone on a map.

All operations are performed secretly, the attacker will not notice anything. Disadvantage of the application - required root rights, installation and configuration can only be done by advanced users.

This app can't search lost phones. But it will be able to stop an attempt to turn off the smartphone or put it in airplane mode. In response to these actions, the device will turn on loud sound signal, revealing the attacker. The application will also sound a signal if there is an unauthorized attempt to pull the smartphone out of your pocket.

Paid functionality – 75 USD/month. If paid annually, the monthly cost will be 27.42 USD.


Today, 99% of people on Earth carry their personal leash and collar in their pocket - this is their favorite smartphone. Not every person thinks that a mobile phone or an advanced smartphone is not only a means of communication, but also a device that allows you to determine the location of its owner. Why is phone location tracking useful?

Why do this?

Find out where the owner of the phone is through the device itself - this function is useful for parents whose children are just starting to move around the city independently, for example, going to school and home after school lessons. This way you can find out whether the child attended lessons and where he was after they ended. If possible, it is worth connecting the phone tracking service to the devices of elderly parents, especially if there is a possibility that a person may feel suddenly unwell, or forget the address of his residence and the way home.

The function is also useful in any extreme situations, for example, when a person is in an area where a natural disaster is raging, mass riots or military operations occur.

Probably the most common reason why men and women want to connect the tracking function to their other half’s mobile device is jealousy and mistrust of their partner. In this way, a jealous person carries out surveillance and checks on his spouse.

Search service from mobile operators

Location tracking mobile phone— the very idea of ​​surveillance seems not entirely ethical, but it does not always have a negative, espionage connotation. For example, if a subscriber himself wants to activate a function on his phone, it is provided by four main operators in the Russian Federation:

  • Beeline;
  • "MTS";
  • "Megaphone;
  • "Tele 2".

Operator services have specific name, activation procedure and cost according to the tariff plan. When connected, an SMS message is sent to the subscriber’s phone with a request to activate the tracking function. The owner of the phone must agree to this request.

"Beeline"

In order to activate the service for tracking the location of a mobile device, you need to send an SMS with the letter “L” to the number 684. The function is enabled for one time, that is, for one request. Each activation requires confirmation of the subscriber's consent. Another method is an open call to 068 499 24. The cost of the surveillance function is from 2.5 to 5 rubles. It works during a call between phones.

The Beeline-Coordinates tariff service is a constantly working tracking service, to which you can connect up to 5 subscribers at once, of course, with their consent. You can activate it for free in the communication store or yourself.

To activate, you need to send an empty SMS to 4770, or call 0665. The service is controlled by sending commands to 4770. To request permission to track a subscriber's location, you need to send an SMS with the subscriber's name and number to the specified number. Next, the desired subscriber receives a request for his consent. If he answers “Yes,” a message with his coordinates is sent to the searching subscriber. After such confirmation, all subsequent location request sendings do not require the consent of the desired subscriber. The possible error of determination is from 250 meters to a kilometer.

"MTS"

The operator provides a service to determine the location of the phone and its user, which is called “Child under supervision”. It is successfully used by parents to keep their child under control. To activate, you need to send the word “mom” or “dad” to number 7788, and the service is free for the first two weeks. Further, its cost is 50 rubles per month.

In response to the request, a message is received with a unique code, which is assigned to identify the family. Next, it needs to be used to connect the second parent and the child himself. To register from a child’s phone, you need to send a message to number 7788 with the following content: CHILD<ИМЯ> <КОД СЕМЬИ>. The service is also managed by sending messages to number 7788. For example, to receive information about the whereabouts of a child, you need to send an SMS with the text WHERE<ИМЯ>. In response, you will receive a message with approximate coordinates, as well as with a link, following which you can see the location on the map.

For large companies, a corporate communications package is offered, used to track a large group of people (employees), to control logistics routes, freight and passenger transportation.

"Megaphone"

This operator provides its users with several mobile phone tracking plans.

“Beacon” is convenient for parents who are worried about their child and want to know exactly where their child is at the moment. The service can only be activated for subscribers with tariff plans“Smeshariki”, “Ring-Ding” or “Dnevnik.ru”, that is, specifically for children's tariffs. For the Beacon to work, MMS services must be configured on the mobile device, and the account must have a positive balance.

You can activate the service in several ways:

  • through sending SMS;
  • via USSD command.

In the first case, you need to send an SMS with the following text to number 1410: ADD ХХХХХХХХХХХ (subscriber's phone number that begins with the corresponding code, for example, +, +7, 7, 8).

Connection via USSD command occurs in this way: enter the combination *141*ХХХХХХХХХХ on the phone. Next you need to press the call button. You can connect another follower in the same way by entering the number of another follower.

By dialing the code *141# on their own phone and pressing the call button, the parent will receive an MMS message with a map fragment displaying the child’s location.

A service called “Radar” allows you to monitor subscribers not only within the network, but also those connected to MTS, Beeline and Tele2. “Radar” is activated after installing and configuring the geographic tracking area. To activate, you need to log in to radar.megafon.ru and set the monitoring parameters in the appropriate tab. Data about the movements of the tracked object are stored on the website for 90 days.

The service, which can be used without the subscriber’s knowledge, works through mobile app, and you can also use it online, on the operator’s website in the “Locator” tab. It should be noted that connecting a mobile device to the service still requires confirmation from the subscriber, but you do not need to obtain consent every time you request a location.

“Navigator” from Megafon is activated through the website m.navigator.megafon.ru, or through the mobile application.

"Tele 2"

The operator provides a service called “Geosearch”. Capable of tracking a mobile phone with any technical characteristics, from modern smartphones to push-button rarities. The searching subscriber receives information either through SMS messages or through the application interface. To activate, you need to send a USSD request *119*01#, use the command *199*phone number# to connect the desired number. Through the USSD menu *119# and the “Find” function, you can obtain information about the subscriber’s position. When sending a request to determine the location, the desired subscriber will receive a corresponding request. If the subscriber does not respond to the request with consent, it will be impossible to obtain data about his location.

Search via satellite

Knowing how to locate your phone via satellite can help you locate your lost or stolen device. There are several search options using satellite communications:

  • by IMEI number;
  • through GPS and special direction finder programs.

To find a phone via IMEI, you first need to know this code - a sequence of 16 or 17 digits assigned to the phone as a unique identifier. The information is located in the phone's memory; in addition, it is indicated on the warranty card and on the phone's battery.

The code is assigned to the device when assembled at the factory. Theoretically, it can be changed by flashing the phone, although modern manufacturers install protection against flashing and changing the IMEI code to protect phone owners from theft. Finding out the phone code is easy - to do this, you need to press the key combination *#06# and the call button.

You can use this information to search for a phone by satellite only by contacting law enforcement agencies with a report of theft or loss. Police officers will ask you to show a coupon, receipt of purchase, and phone box. If the phone was brought into the country legally, police officers will scan the location of the device.

iPhone owners know that when purchasing a phone, you need to register in the iCloud system and activate the search service in the menu. To track your smartphone, log into your iCloud account, enter Apple password ID, click “Search my iPhone”, and then navigate using the map that opens.

A similar function works on phones with operating system Android system. For Android, the algorithm is as follows: you need to open “Device Manager”, enter account Google, detect device online.

Device Manager is a function that is provided to search for a phone and obtain information about its location. With its help, you can even make a remote call on your smartphone, or delete information from it.

To use, the smartphone must be synchronized with the owner's Google account. To enable the function, you need to go to the “Settings” section, go to “Security”, select the “Device Administrators” subsection. Next to the name “Device Manager” you need to check the box. Then you need to click the “Activate” button.

Searching for a lost or stolen smartphone occurs through the website www.google.com/android/devicemanager. When you first visit the site, you will need to agree to the Device Manager terms to use location information.

After this, if the lost device is connected to the Internet, it can be found on the website by cellular networks, Wi-Fi or GPS.

Windows Phone offers online search through the website of the same name.

Another way to search via satellite communication is to visit the Glonass website, Monitoring section. Owners of smartphone communicators can use it. To track a device, you need to register in the system, indicate your mobile number, SIM card of the device you are looking for, full name and address.

Services and programs

All applications and tracking programs that allow you to find your phone via the Internet on websites, or using your own mobile phone, are official or so-called spyware. In the first case, the desired number receives a notification that someone is interested in its coordinates. In the second, programs are installed on a mobile device without the owner’s knowledge, do not send him any notifications, and do not detect themselves in any way. Such surveillance is illegal and may result in administrative or criminal liability for the spy.

Sygic Family Locator - the program tracks the location of subscribers registered in it by phone number, and reports the battery level. Works on Android and iPhone, however, for owners Apple gadgets is paid. In addition, Sygic Family has messenger functions. Other legal services are “Child under supervision”, “Radar”, “Locator”, described above.

Find your phone

To find your phone number, you can use the following services:

  • the PLNET service, also known as the website www.phone-location.net;
  • applications Friend Locator, Family Tracker, Locator from Russia.ms - they can be downloaded from Play Market to your Android phone;
  • for iPhone: Find My iPhone or Tracker Plus apps.

Check your mobile phone surveillance

There are several tricks to find out if a specific mobile device is being monitored. By dialing *#21#, you can determine whether call forwarding, SMS and other information is enabled. Such functions can be activated by jealous spouses, or parents who control and protect their children. Sometimes elderly people become victims of surveillance and may hand over their phone to a scammer, for example, so that he can make a call from it. Uncoordinated forwarding threatens that strangers gain access to the victim’s circle of contacts, personal data, daily routine, and sometimes even to her financial means.

You can find out where calls and SMS are forwarded when the phone is unreachable using the code *#62#. To reset all types of forwarding, you need to dial the code ##002#.

If the Netmonitor utility is installed on your phone, special codes make it possible to track the phone’s location and find out whether the device is being monitored:

for iPhone: *3001#12345#*, and for Android: *#*#4636#*#* or *#*#197328640#*#*.

In the Netmonitor program, you need to go to the UMTS Cell Environment tab, then to UMTS RR info, record all Cell ID values. These numbers indicate the numbers of base stations that are located nearby. By default, a mobile phone connects to the base that gives the strongest signal.

Returning to the main menu, you need to select the MM info tab, then Serving PLMN. Values ​​are displayed here Local Area Code. Using two categories of values, using a regular website under the fourth tab in the menu on the left, you can identify the location base station to which the phone is connected. If such a base is a mobile station such as a minibus or KamAZ, this should alert you. Operators usually do not use mobile bases, except in areas where there is no coverage from fixed towers - in this way they can track and listen to calls.

Ethical side of the issue

If we are talking about an adult and capable person, any surveillance of him without his consent is unacceptable. So, for example, connecting a location determination service to the mobile phone of a child or elderly parents in order to protect them from troubles and come to the rescue if necessary is a completely justified move. Regarding installation spyware without the subscriber’s knowledge, this is what jealous husbands and wives usually do—a direct step towards completely ruining a relationship with a person. After all, who would like trying to put an adult “on a leash”?

Services and programs for monitoring a mobile phone can be legal assistants when you lose your phone or for monitoring minor children. If location tracking is espionage, in some cases their installation and use may result in administrative or criminal liability. You need to use such means of calculating the location of a mobile phone wisely and with caution.

We already told you how. Today we will talk about determining the location of the phone. Determine the location of the phone on Android based Can different ways. I'll tell you about the best ones in my opinion.

This can be useful not only from the standpoint of hiding or finding a lost or stolen device, but also if, for example, it is necessary to monitor the location of a child or other family member.

How to track your phone's location

For this purpose, a number of applications have been created from Google, as well as individual utilities that are some kind of social direction finders, such as, for example, Life360.

The operating principle of both is based on the collection and processing of data from technologies such as GPS, Wi-Fi, GSM and others.

How to track location using Google

Today there are 2 methods - respectively 2 applications. You will need to have access to the device that you are going to track, as well as login data for the Google account used on this device.

Track location using Google Maps

Tracking function built in as standard Google app Maps (hereinafter GM). And it’s called “Geodata Transfer”.

To track your phone's location you will need:

  • this application, both on your device and on someone else’s
  • access to someone else's device
  • Google account information used on the last one

So, go to GM on the phone whose location you want to track. Open the settings tray and go to the “Geodata Transfer” function.


Here, click “Start” and choose how long the device will show its location. Now mark who will see it (from contacts).

NOTE
Before doing this, you must add your account (which will be able to see your location data) to your contacts on your device.


Track phone location from using Google Maps

You should see a message telling you that you are showing the other person where you are.

Track phone location using Google Maps

All that remains is to log into GM on your device (it must be connected to the account that you specified in contacts on someone else’s device). At the top, select the icon of the person you will track. That's it, you see his location.

NOTE

You can also allow another device to see your location.

Track phone location using Google Maps

INTERESTING

Previously, the tracking function was also in social service Google+. And in GM, using the “Show where I am” command, you could reveal your location to someone. Now the developers have finalized the “Show where I am” command in new feature"Transfer of geodata." When you select “Friends on the map” in Google+, you will be automatically transferred to GM.


Track phone location using Google Maps

Track location using Find My Device

This is a specially developed tool that consists of two parts - an application on your phone or tablet and a corresponding web resource in Global network(website).
The first works in conjunction with the second. If the phone was stolen, for example, then you can go to the Google website through your browser, go to the Find My Device section and perform a number of actions, which will be discussed below.

Also, which is very important, if you install the application on someone else’s phone and know the Google account details (mail and password) to which this device and the application itself are connected, you will be able to track it both from another smartphone and from a PC. Now I’ll tell you more.

The first thing you need to do is install the Find My Device application in the Play Market. Then log in using the account that is connected to your device. Be sure to give access to location data.


You have all moved to the application interface. Here you can see information about the battery charge and connection on your phone. You can also perform a number of actions: for example, ring your phone or block it. The “Clear data” item is not displayed, since the application “understands” that it is running on the same device.


Location by phone using Find My Device

When you log into an account that is on the same phone, all these functions seem useless. However, if you log into the account of another device, you can perform all these actions remotely.
This will be especially useful if the device has been stolen or you simply cannot find it. Go to the Find My Device website. Log in with the account that was connected to the device.


Location by phone using Find My Device

You see the same features and location, of course. Now everything is simple: if you can’t find the house, call, it was stolen or lost on the street, at least block or completely erase the data.

Popular Location Tracking Apps

As you understand, there are quite a lot of these applications. Here I will describe only 3 of them that I liked for one reason or another: functionality, performance, design, focus, etc.

Zoemob

This application helps you track the movements of your family members. Essentially, you create a group where everyone can see the location of others, as well as their message and call history.

Friend Locator

This app is included here not only because it is very simple and convenient for tracking location and getting information, but also because it is completely free.

Tracking by phone number

It seems that it is not the most popular program on the Google Play Market, you might say. However, this is not at all true. Since the application is paid, many functions are closed. Therefore, people, without understanding, give low estimates.

This is actually a very functional application. You can track any device by phone number. And if you install this client on your device, you can:

  • make it invisible
  • remotely receive recordings of conversations and messages
  • remotely receive screenshots
  • monitor application usage data

Life360: be with your family

I really liked the application. I started using it myself. Honestly, this is not just a tracking tool - it is an entire social cross-platform system.

You can create different user groups and communicate with them. Besides this, there are many other free and paid features.

Free Features

After registration, you are immediately prompted to enter a code to join any existing circle (group). When any circle is created, it is immediately assigned a code. With its help, users can be added there. You can also create any circle yourself and send the code.

Once the circle is created, you can add places and locations to it. For example, a house, work or a certain area (places). Thus, when one of the circle members leaves or enters it, you will know about it. Agree - this is just a great solution for parents.

Among free features In addition to these and chat, there is also the ability to set up notifications about the battery level on the device of any of the circle participants.
And one more thing that is very important is the ability to configure a panic button. If necessary, you can click on this button to send your location data to selected contacts.

Premium account features

There are several benefits to the premium account that I think are worth paying the $5 per month for.

Firstly, this additional function Driving. This is a whole segment of this platform, with the help of which the driver’s driving style is monitored. Thus, when an unsafe style is detected, the application automatically notifies certain members of the circle (for example, parents) about this.

Other useful and interesting features:

  • possibility of creating unlimited quantity places
  • location log for 30 days
  • optimized location updates for circle members

Also, according to Chris Hulls, the creator of the platform, Life360 plans to create a joint calendar and problem book. And this, as you understand, will significantly expand the capabilities of the application. And it will make it possible to carry out joint planning from anywhere in the city, country, or even the world.

Conclusion

As you can see, tracking your phone's location is quite easy. And there are many ways to do this. Above, I described the most popular and convenient ones (in my opinion).

There can be countless applications. However, the main one is security and monitoring. Also, location tracking, as it turns out, can also be used socially. And there are entire platforms for this, such as Life360.

One of the modern methods for tracking mobile phones is GPS system monitoring. It allows you to track your phone via satellite online. The program is designed to work with devices equipped with trackers. The latter, as a rule, is a receiver with a special module that calculates its coordinates.

By receiving data from the server, a person can monitor the location of the phone. This system has many advantages. So, if a mobile device is lost, its owner can turn to GPS. Then use the search network to find the lost device.

Why and for whom is monitoring needed?

Finding a means of communication will be useful for those who have elderly relatives. Many of them do not live very close. You can monitor the number via satellite whenever you want.

Parents will also find it helpful to learn how to track their child's phone using GPS. If a student decides to go for a walk, thanks to the coordinates you will monitor his mobile phone. You will be calm and confident about the safety of your child.

How tracking works

1. First, you need to connect to satellite monitoring. For example, the Maps-Info website has a corresponding section.

2. You must have a communicator (built-in or connected) in your smartphone. Through it it will be possible to track the phone number.

3. After successful registration, submit the request necessary information. Send your subscriber number and the one you want to control.

4. Online satellite tracking begins as soon as you click the “Search” button. In terms of efficiency, GPS search is not inferior to GSM mobile device detection systems.

5. In a couple of seconds, all the information about the person’s location is at your fingertips.

Other ways to find out your location

Someone can contact telecom operators and find out where the target's phone is located. But this is not always effective. Since some operators refuse to provide this service. There are also those who will ask you to pay money for this function.

Therefore, it is better to go to the trusted site using the link below. Here are the latest methods for monitoring communications. This way, you can control the actions of the person you are interested in.

At the same time, you will receive a guarantee that you will not be detected. You will also be able to receive 100% truthful information.

How to find out by phone number where a person is without his consent is a question that worries some users. You can find out a person's location by his phone in several ways, depending on the operator.

Sometimes users mobile devices you need to find out the location of a certain person. This is due to many reasons. GPS is usually used to locate the device - satellite system communications. The satellite determines the approximate location of the person and sends a request to the towers mobile communications, located as close as possible to the intended point. How better phone receives a certain signal, the closer it is to a specific tower. But this is just lip service.

Officially, the satellite communication system will not provide the average user with the location of another person, no matter who he is. The location can only be disclosed with the consent of the subscriber, since the contrary is prohibited by international law.

How can you use operators to find out where a person is?

Mobile operators can indicate a person's location by phone code. The first three digits, responsible for the operator, are not clearly distributed between the last ones. The next three clearly indicate the region.

MTS

MTS phone numbers begin with 910–919 or 980–989.

Beeline

Beeline phones contain codes 902–906, 930–939.

Tele 2

Tele 2 codes: 900–902, 904, 908, 950–953, 958, 977, 991–996 and 999.

Megaphone

Numbers starting with 920–939 identify Megafon.

Is it possible to determine where a person is by phone number?

Sometimes you can determine the location of a person only by number:

  • the first digit indicates the country of residence;
  • the next three digits identify the mobile operator;
  • There are also three numbers after the region. They are responsible for the region of the country in which the subscriber purchased the SIM card.

The location of a person can only be determined with his consent. But there are unofficial ways to find out the subscriber’s location.

Via computer

The easiest way is to use a computer. The Spy Bubble program helps you find out a person's location as accurately as possible. Moreover, it has a built-in stealth mode. It is used if the searcher wants to hide the use of the application. The quality and stealth mode cause the disadvantage of the program - it is paid.

Online

To determine the location of the subscriber, you can use Android applications or online services. The proposed utilities are suitable for both Android and iPhone:

  1. Where's my droid is a program developed for android. It has a simple interface and only requires a phone number to operate. The location of the smartphone is determined by satellites and only approximately.
  2. Live GPS Tracker tracks the location of the device in real time if it has GPS enabled.

These apps are free and help track the device's position without the subscriber's consent. But their disadvantage is that they need to be installed on the monitored phone. For example, parents can monitor their child. Remember that you need to explain to your child the purpose of installing the application.

Is it free?

These programs are free, but have significant drawbacks. They do not work well in regions with poor communications, and in large cities they show the location with an error, which is caused by the density of buildings. If the monitored device turns off GPS, it will not be detected.
