Find a phone number near you?

Question

Burglary protection

Is it possible to collect data on phone numbers near you (well, for example, within a radius of 100 m.).
Example: I'm in a cafe, and somehow my program records the phone numbers of people near me.
I know it's a dumb question, but I thought I'd ask anyway

Answer 1

You, theoretically, will be able to get a list of IMEI and TMSI subscribers from the air who are near you. But this will give you absolutely nothing, because. you won't be able to match a TMSI to a phone number without access to carrier databases.

Answer 2

Options: -The
authorities and operators have access -You
can buy a portable BS like those that use the authorities
-You can try to have a wifi point and if you get access to the captive portal database, you will find out through which numbers people are authorized
-You can make your own point with your captive portal, then the people will automatically cling to this point and if they want to access the Internet, they will have to log in, respectively, you will receive a number

Answer 3

Methods according to the level of complexity (the higher, the easier):
1) Come up and ask the person for his phone number
2) Make an absolute copy of the Wi-Fi point to which the victim usually connects. That is, the entry window through the number should be identical with respect to the original. Then somehow force him to enter Wi-Fi through this point
Cons:
1) The victim is not an idiot
2) You will need to somehow contact the victim
3) Make friends with the owner of the Wi-Fi point to which the victim usually connects. Then look at the database of all who connected
Cons:
1) The owner is not an idiot
2) Of the thousands of numbers, you will not understand which one you need

Answer 5

There is a possibility if you provide communication services either from the police. After committing a particular crime, the police can call people whose phones were near the scene of the incident - which means they have such functionality.

Answer 6

Earlier in Moscow, when I drove near certain stores, even underground, in the subway, SMS inviting me to the store came to my phone. I don’t even know how they did it, but I think there were such commercial services. You can search from this side
