Sometimes there are situations when someone called you, but for a good reason it was not possible to pick up the phone, and the number displayed on the screen is unfamiliar. You are beginning to wonder who it was. But making a call back is embarrassing, or you are simply afraid to get caught by mobile scammers, as a result of whose actions a certain amount of money may disappear from your account.
Instructions
Step 1
Learn the general rules for dialing. Once you know the basic information, it will be easier to navigate to figure out where the call came from. When entering a long distance and international number from a landline phone, you must enter certain combinations of numbers. For long-distance connection - 8 - dial tone - area code and phone number; for international - 8 - dial tone - 10 - country code - area code and phone number.
Step 2
After analyzing the information received, you can easily determine the territorial affiliation of the caller. To call a mobile number for a long-distance connection, dial - +7 - city code - phone number; for international dialing, use the combination - + country code - city code - subscriber number.
Step 3
Now that you know the basic combination of numbers, move on to defining the country code. Using the telephone directory or on the Internet, find a list of state telephone codes, referring to the above dialing scheme, determine the country or city from which the call was made.
Step 4
Sometimes it happens that the caller hid the mobile phone number. This is often done for the purpose of extortion, pranking, or to intrigue a person. The automatic subscriber service will help to calculate the "joker". His number is 0880. Having called him, wait for instructions from the answering machine. He will indicate the sequence of actions, then enter the password, and in the menu for adding / removing services, set the option "Internet subscriber service".
Step 5
The next method, which allows you to find out the caller's data, is to order a service from a mobile operator that identifies any calls, even hidden ones.
Step 6
You can also order a detailed printout of incoming calls to your number. If you are constantly harassed on your home phone, and there is no way to identify the caller, your service provider may provide a malicious call identification service. Enter the combination of numbers that is indicated in the detailed instructions for this option.
