Worrying about its customers, it offers a wide range of services, useful options, favorable rates, and, which is not unimportant, the management of your own number through the tools of your personal account. To achieve this goal, service telephone numbers are used, as well as USSD commands Megaphone...

USSD balance management commands

We already know the most necessary and important numbers of the MegaFon help desk. Now let's take a look at the commands that are responsible for the balance. The main USSD command is *100# , which defines the current account of its owner. This simple number can be learned easily or entered into the contact book.

If using the command *100# If there are problems (information is not visible or it is difficult to distinguish), then you can always find out your balance by number 0501. The autoinformer will tell you it.

Next USSD request *550# informs about the detailed balance. A text message arrives on your mobile displaying the following information:

• Available funds;
• Provided limit;
• Current balance.

Available funds are the sum of the current balance and the money limit provided by the operator. In order to receive information about available minutes, SMS and Internet traffic, the MegaFon network has a command *558# ... By sending such a request to the operator, in a few seconds you will receive an exhaustive answer to your question.

Mentioning all the useful numbers of the operator for managing the money account, one cannot fail to note the bonus program. To find out the balance of bonus points, you need to send a request *105*5# ... Also, this request will help you and exchange your points for a variety of rewards.

Team *512# will allow you to see information about the last five debits from your money account. In a few minutes you will receive an SMS with a decryption about the last charges to your number. The command is very useful for detecting money leaks from your phone balance.

USSD commands Megafon with zero balance

Let's look at some of the USSD commands of Megafon, which are directly related to the balance, from the category "Opportunities at zero":

• * 144 * subscriber's number # - USSD-command of the "Call me back" service. By sending such a request with the number of the called subscriber, he will receive a short notification with a request to call back;
• * 143 * subscriber number # - USSD-command, which implies replenishment of the account for the subscriber who sent such a request. And in the request itself, the phone number of the subscriber to whom you are applying with the request is indicated;
• * 550 * 1 # - USSD-command, which makes it possible to activate a useful service - Credit of Trust. What does this mean? Megafon gives its customers the opportunity to obtain a credit limit, with the help of these funds you can use all the services provided;

This includes the simplest command that allows you to control the paid services connected to a given number. By typing the combination *105*503# , you will receive detailed information about the amount spent from your account.

Using the USSD command *105# you can manage services and rates on your number. And it is not necessary to do this only through the "Personal Account". This request gives the subscriber solid opportunities. Namely: disconnecting or connecting certain services, managing tariffs, working with a bonus program, obtaining a variety of reference information.

• * 205 # - in order not to look for your number for a long time, dial this combination;
• * 105 * 503 # - a request that allows you to get a list of paid services assigned to your number.

You can find anything on Google. Just not your phone number on the SIM card.

How can you find it out - quickly and from any operator?

Collected all methods in one material.

Universal ways

• Look in the agreement with the operator or on the starter package;
• Call the operator and ask;
• Call the number of a person in whose phone book you are not. The number will be displayed on the screen;
• Call the number of the person who has you in the phone book. After that, he will be able to find out your number by clicking on your name in the call list.

MTS

• command * 111 * 0887 #;
• call to number 0887;
• in the application "My MTS" (version for iOS, Android).

Beeline

• command * 110 * 10 #;
• call to number 067410;
• in the application “My Beeline” (for iOS, Android);
• for USB-modem: in the application "USB-modem Beeline" go to the section "Account Management" and select the item "My number", then click "Find out the number".

Megaphone

• command * 205 #;
• enable data transfer ( Mobile Internet) and go to the site megafon.ru (or to the regional sub-site). The number will be displayed in your personal account, and on the remaining pages - at the top of the screen;
• in the Megafon Personal Account application (for iOS, Android).

Tele2

• command * 201 #;
• in the application “My Tele2” (for iOS, Android).

Yota

• command * 103 #;
• in the Yota app (for iOS, Android).

Methods for iPhone

• “Settings” - “Phone” - “My number” (above);
• Home menu - "Phone" - "Contacts" (above);
• In iTunes: "Devices" - "Summary" - "Phone Number".

Method for iPad (with 3G / 4G)

• “Settings” - “Cellular data number”.

Method for Android

• “Settings” - “About phone” - “Status” - “SIM status” - “My phone number”.

If you have a skin for Android installed, the item names may differ.

It happens that the number is not shown. This happens when you reissued or changed the SIM card in the operator's salon.

Employees copy from the old card to the new encryption keys and another important information... But they forget to fill in the “Own number” cell.

Messengers

• WhatsApp: click on the three dots in the upper right corner - "Settings" - touch your nickname. The number is the very last line.
• Viber: click "More" (button in the lower right corner). The number will be displayed under the avatar and nickname.
• Telegram: main menu (three bars in the upper left corner). The number will be visible at the top.

Why is it also important to know your number

When you buy a beautiful number from your hands, a completely different value may be written to the memory of the SIM card. It is stored in the “Own number” memory location.

If a fraudster has changed his “Own number”, then a beautiful number will be displayed in the smartphone settings. And on the network - a real one, issued by the operator.

Calling another number or checking in the ways that the operator offers will help you not to be disappointed in the purchase.

And in general, it is not safe to buy numbers from your hands. If you then bind such a number to a bank card, the real owner of the number will be able to get a duplicate SIM card and leave you without money.

How to change the number directly on the SIM card

Find an old push-button Siemens A50 or its “colleagues”, insert a SIM-card into it, find “Your number” in contacts and write whatever you like there, then save it. You may even not follow the format.

Another option is an ancient smartphone with Android 4.1 and below.

• Go to “Settings” - “SIM card management” and disconnect the desired card (or switch to airplane mode).
• Click on the name of the SIM card and go to the section "Information about the SIM card".
• Select the item "Enter phone number" and enter the desired number.

The same works in some Android skins (like MIUI).

But in any case, your number on the network will not change from this. Otherwise, everyone would have walked with beautiful numbers.
