How is subscriber tracking done?

Information is collected in several ways: when a cell phone establishes a connection with an operator’s tower, when using Wi-Fi wireless Internet networks. Antenna towers analyze the signal sent by the mobile phone and then calculate which towers are closer to the mobile phone. The location of the mobile phone is estimated by comparing the signals sent by the mobile phone to the antenna tower.

Each base station broadcasts information about neighboring stations, indicating the frequencies on which they operate. The phone constantly measures the signal strength from each of the base stations and, if necessary, selects the one from which a clear signal comes. Having the coordinates of the six base stations closest to the phone, you can accurately calculate the coordinates of the phone without any GPS. If there is no data on the location of base stations, then it will not be possible to calculate the location of the phone.

Standard method

This option is not suitable for all Android phone owners. However, it is convenient because it does not require an Internet connection. In addition, as a result, a blacklisted subscriber trying to reach you will hear that the subscriber is unavailable, and not short beeps, as if you were just talking to someone at that moment. The first thing you need to do is go into blocking mode. Some people may not need this, but on most models it is necessary to access all call setup features.

Go to “Settings”, there turn on “Blocking mode”. After that, return to your desktop and go to Phone. Click on “Options”, then “Call Settings”. Here you will find a long menu in which you need to find two functions: “Call Rejection” and “Call Forwarding”. Call Rejection allows you to manage your blacklist by adding or removing numbers from it. In addition, you can limit calls from certain regions or from certain telecom operators. Call forwarding is needed in order to create the illusion that the subscriber is not on the network. In order to do this, you need to take the operator number from the “If unavailable” line and insert it into the “If busy” line. If you don't do this, the blacklisted person calling you will only hear short beeps, indicating that you are busy talking to someone else. It is worth noting once again that this method of creating a blacklist on Android is only possible for some phone models, mainly Samsung.

A way to determine that the phone is in flight mode or the number is in an emergency

Many subscribers have repeatedly wondered when receiving a robot answer what was actually wrong with the subscriber’s phone. Perhaps he turned it off himself or added our number to the blacklist. And now we just can’t get through to him. In most cases, if you hear a message that the device is deactivated or out of network coverage, then the phone is actually turned off or there is no service in that area.

It is quite difficult to determine the status of the phone only by the robot’s response. Since some Blacklist applications may allow the phone owner himself to set a specific response. This means that the subscriber can choose what answer will be heard in our devices. It also means the same for the base station that the subscriber has turned off his phone or set it to airplane mode. The mobile device simply disappears from the cellular network map.

Block using operator services

You can also get rid of unwanted calls from a specific phone using the services of your telephone operator.

Blocking with the help of an operator is good because the blocked caller, when calling, will hear words about the subscriber’s unavailability, and if many users block the same number (for example, an advertising one), then the operator will check and may stop service.

The disadvantage of this simple feature is that some operators provide it for a fee.

MTS

The operator under discussion offers several types of blocking lists and blocking capabilities.

Add the subscriber to the list of prohibited subscribers by dialing the USSD request *442#. In the next step, you will need to enter the number of the subscriber who is bothering you, which you need to block.
Or send an SMS message with the text 22* (the number of the blocked phone in 11-digit format without spaces) to 4424.

At your choice, the subscriber will hear short beeps (Busy) or an unavailable notification. Using this feature limits not only incoming calls, but also SMS messages (the sender will not see delivery information). Using the service has some restrictions:

Works only on tariffs with activated SMS PRO service. It is free, to connect, send SMS ON to 232.
Not valid on Cool, Connect, Online, MTS iPad tariffs.
You cannot block incoming MMS.
The maximum number of subscribers in the blocked list is 300.
The cost of providing access is 1.5 rubles/day, connection and disconnection are free. The daily fee begins to be debited from the day when you added the first subscriber to the emergency situation.

You can disable access by sending a USSD request *111*442*2# or an SMS message to 111 with the text 442*2.

Megaphone

Activation and deactivation is free of charge. The daily fee for its use is 1 rub./day. There are two activation methods:

An SMS message with the word YES sent to toll-free 5130.
USSD request *130#, call key.

After this initial connection, you can add to the list of subscribers. This is done like this:

Request *130#, and then follow the instructions (you will need to enter contact information for blocking).
SMS to 5130 with the text +(space)(unwanted subscriber phone number starting from 7). To remove from the emergency situation, replace + with -.

The LIST command via SMS to 5130 will show who is included in the emergency situation. OFF at 5130 will disable access. During a call, the blocked person hears a notification about an erroneous dialing.

Has the following usage restrictions:

The maximum number of contributions to the emergency situation is 100.
SMS, MMS cannot be blocked.
If your balance is zero or negative, you will receive incoming calls.
Proper operation is not guaranteed abroad, with foreign license plates.

Although the service is cheaper than MTS, its capabilities are narrower.

Tele 2

All management of this regional operator occurs using USSD requests:

Connect *220*1#.
Disable *220*0#.
Add *220*1* (number in international format starting from 7)# to the list of prohibited calls.
Remove from emergency *220*0*(number)#.
If a message comes from a spammer whose data is indicated in Latin letters (alpha-numeric), then you can enter it into the emergency situation using an SMS message to toll-free 220 with the text 1* (the name of the subscriber as it was determined).
Remove alpha numeric from emergency situation – SMS to 220 with the text 0*(name).

Connects to all tariffs, with the exception of Modem. Turning on and off is free, the subscription fee is 1.1 rubles/day. The cost of adding to the list is 1.6 rubles/entry.

The blocked user hears a message that the subscriber is unavailable when calling you.

Use call notification services

Mobile operators offer services that automatically send SMS as soon as a subscriber who was “temporarily unavailable” appears on the network. This is a convenient way to track the appearance of the desired subscriber, and the simplest solution to the problem of communication interruptions.

The Subscriber is not answering application - Temporarily forwards incoming calls to the answering machine of your choice. The “Subscriber is not answering” program allows you to be “out of reach” if necessary, although the phone remains turned on and all services are working (outgoing calls, SMS, MMS, mobile Internet.

If you have an important conversation on TELEGRAM, SKYPE, VIBER, WhatsUp or using other IP telephony programs, then select the “COGNAC” mode and rest assured - your conversation will not be interrupted by a GSM call!

If you need to take a break from talking, but control who called you, then use the “MEETING” mode. calls will be received on your phone in silent mode for a few seconds and then sent to the voice message you have selected.

The main convenience is that the INITIATIVE OF THE CALL DOES NOT PASS TO YOU, that is, those who called you, having heard the answering machine “the subscriber is not answering,” will call back themselves! It is very comfortable.

ATTENTION, ON PHONES WITH A 2nd SIM CARD, THE CORRECT OPERATION OF THE APPLICATION IS NOT GUARANTEED, BECAUSE ALL MANUFACTURERS IMPLEMENT THE FUNCTIONS OF THE SECOND SIM CARD IN THEIR OWN, NOT STANDARD, FUNCTIONS!!!

The difference between the “COGNAC” and “MEETING” modes is that in the “meeting” mode you will see phone numbers in the list of missed calls, but not in the “cognac” mode.

Dear users! If you have deleted the application and calls still do not go through to your number, dial ##002# and press the call key.

Voice Message Options:

1. “The subscriber does not answer or is temporarily unavailable.”
2. “The subscriber’s device is turned off or is out of network coverage.”
3. “This type of communication is not available to the subscriber.”
4. Israeli cellular network answering machine
5. there will be others

If you have ideas for new autoresponders, send a text, we will be happy to implement it :). After the time you set, the answering machine will automatically turn off. The operation of the program does not affect the reception and sending of SMS, MMS and the ability to make outgoing calls. While the application is running, a white ball will appear in the status bar, which will display the remaining time in minutes.

Explanation of the rights requested by the application:

a) “Access to calls” - for sending commands to set and remove call forwarding.
b) “Internet access” - to download advertisements.
c) “Access to memory card” - the program writes its state to the card in case the phone’s power is turned off.
e) “Start when the phone is turned on” - in case of power failure of the phone. When the power is restored, the program will turn off the answering machine in time.
f) “Disable sleep mode” - so that the program can clearly work when the phone “falls asleep”.

How and why to enter a blocking password for incoming calls

Every phone owner knows firsthand the situation when the phone starts ringing at the most inopportune time, distracting you from work or other important matters. Of course, no one forces you to answer the call, but it happens that the smartphone continues to treacherously notify about incoming incoming calls. And this is especially annoying when most of the work is done through the phone, which is not uncommon today.

A way out of this situation may be to block incoming calls.

The function will protect against intrusive calls, leaving the mobile Internet on. In addition, barring outgoing calls will protect contacts from accidental dialing in the event of handing over the smartphone to a child. This option is not known to every Android owner, but it is this operating system that provides users with ample opportunities.

To bar calls:

Go to "Phone" and open the application menu.
Click on “Settings” and “More” in the section related to the SIM card whose activity you want to block.
Open the “Call Barring” section and block those that are necessary (all, outgoing or incoming).
Enter the password, most often it is “1234” or “0000”, depending on the type of cellular operator.

To unlock, just carry out the algorithm in reverse order.

Important! On your iPhone, you can simply turn on Do Not Disturb mode, protecting yourself not only from calls, but also from notifications in instant messengers.

How to make your phone inaccessible

Making your phone inaccessible is as easy as shelling pears: you just need to turn it off, or remove the SIM card, and you can also simply set “airplane mode” in the phone settings. In addition, you can change the number and install another SIM card. It is worth noting that these methods make it possible to make the phone inaccessible to all subscribers. But to make a phone inaccessible for one number, you need to blacklist it and add it to the list of prohibited ones. Just like that, you can make your phone inaccessible.

Application

This method is much simpler than the previous one, and all owners of phones on the Android platform can use it. You just need to download an additional program to your smartphone. You need to download it from the play-market, and the Blacklist program is most suitable for regular use. There are two versions of the program: paid and free. In order to create a blacklist of numbers on Android, the free version is quite enough. With its help you can block incoming calls and SMS. It also allows you to create templates for outgoing SMS and automatically respond to incoming calls and messages with them.

Is it good or bad if your phone can be tracked?

By tracking the location of a cellular subscriber, state security agencies can quickly find a wanted criminal.

Cell tower

Also, using a mobile phone signal, doctors or rescuers can find the victim. This is why it is important for cellular operators to use technologies that provide sufficiently high accuracy in determining the subscriber’s location.

The ability to track also allows relatives to receive information about the whereabouts of a child or elderly relative at any time. Many operators have this service in their tariff plan.

Blocking calls while preserving the Internet - step-by-step recommendations

The locking procedure may vary depending on the operating system shell and manufacturer.

For Samsung

Fans of smartphones from the popular South Korean brand can activate the call ban through the system settings, in the “Phone” section.

After the built-in application opens:

Select "Additional Services", which is usually at the bottom of the list.
Go to the “Voice Call” section and “Banning”.
Select the type of calls you want to block.
Confirm the action by entering a four-digit password from your mobile operator.

You can unblock a call by following a similar algorithm.

Xiaomi

You can disable inbox on Xiaomi in a few simple clicks. The necessary function, as on other smartphones, is located in the “Phone” application.

After opening it:

Click on the button to go to the menu, in the form of three parallel dots (•••).
Go to advanced settings and select the “Other settings” section.
Click on “Call Barring” and select the SIM card that will not receive calls (for phones with two SIM cards).
Activate the function and confirm the action.
Enter a 4-digit password (000, 1111 or 1234).

Important! The password depends on the cellular operator, and is usually indicated on the starter package. If the packaging has been disposed of, the combination can be obtained from the operator by answering security questions.

Huawei

The procedure for enabling call barring with active mobile Internet on Huawei is not much different from the standard one.

To block:

Open the “Phone” application and go to the menu by clicking on the button in the form of three dots.
Go to Settings, More and Blocked.
Click on the “Call blocking rules” item.
Activate the "Block" option.

The feature allows you to block all incoming calls or only those that come from unknown or hidden numbers.

For smartphones with Google Phone

You can also block incoming messages on a device with the Google.Phone application installed. Just go to the system utility and open the drop-down menus, where “Contact Settings” are located. Afterwards, all you have to do is go to the “Call Blocking” section and select “Forwarding”.

In the window, enter any number, even a non-existent one, and set the forwarding period to “Always”.

Until the function is deactivated, all incoming calls will not be received on the smartphone.

Secret combination for Android devices

Android users are not even aware of all the capabilities of the device. Some interesting functions are hidden, while others are activated by special combinations. So, by dialing *#*#4636#*#* on your phone, you can disable the “Calls” option, while maintaining the functionality of the mobile Internet. And until the lock is deactivated, the smartphone will not receive calls.

After dialing the secret combination, a special menu will open, where you should click on the “Phone Information” section.

Now find the line “Set your preferred network type”. This can be changed by clicking on the down arrow icon, which opens a drop-down menu with network options. Selecting “LTE Only” will allow data transmission, but will block access to receiving calls. After rebooting the device or changing the network selection, all options will be restored.

What does a subscriber who has been blacklisted hear?

Subscriber

, who is on the black list, when calling your number, will hear calls, but no one will pick up the phone, since calls do not reach this person. Accordingly, if you call this way several times and constantly hear beeps, we can conclude that you are on the black list of the person you are calling.
