In order to legally find out the subscriber number of a cellular network operator, you need a fairly good reason, because just like that, information about customers is not disclosed by any company.
Necessary
a disk with a database
Instructions
Step 1
Purchase a special disk with a database of telephone numbers of subscribers of cellular network operators in your city. It is quite possible that you will need several disks if you do not know which company the subscriber is using. These discs can be found in markets and various stores in your city.
Step 2
Please note that the databases become out of date every week as many subscribers change their numbers too often. Also, the information in these directories may be inaccurate, the disks may contain viruses.
Step 3
Insert the purchased CD into the drive and be sure to check it for viruses. Run the directory and select the search item by last name, first name, patronymic, passport data, place of registration, and so on. Review the displayed results, select among them more or less suitable for your query criteria. Please note that using this method is illegal and may entail certain consequences.
Step 4
Find out the number of the person you are interested in in a more legal way, for example, by searching on social networks. Enter the user's first and last name, view the data on his page in the contacts section. If they are hidden from unregistered users or users who are not on the list of friends, add to this person and view the contacts after he approves your application.
Step 5
Also perform a search query on various city forums, ask people from the list of friends of this person for his cell phone number, or try to find out directly. Do not use paid cell phone number identification services - in most cases you will not achieve the desired results.
Step 6
Contact people who have legal access to databases of cell phone numbers, explaining the reason. Naturally, this should be done only in extreme cases and in the presence of certain circumstances that deserve attention.
