Standard applications and mobile carriers do not reveal a person's geolocation without the phone owner's consent. At most, the only information one can sometimes independently ascertain is the country or carrier code—which, however, does not provide the specific city or region. There are services that operate somewhat differently, and one such service is GEOfinder. Its operating principle involves the system generating a special link, which is then sent to the target phone number via SMS or instant messenger. If the recipient opens this link, the service identifies the device's coordinates and displays them on a map.
