Is tracking any phone by number truly possible?

If a service claims I can locate any mobile device worldwide just by entering a phone number, how does GPS and cellular triangulation actually work, and are results really that precise?

Locating a mobile device globally by its number typically relies on a combination of GPS data and cellular triangulation. While GPS provides precise coordinates, triangulation uses the signal strength from nearby towers to estimate a location, which can vary in accuracy. If you want to dive deeper into these technologies, visiting a specialized forum can help you understand why urban areas yield more exact results compared to remote locations where cell towers are sparse.
