I’m trying to figure out if there’s any legitimate way to locate a phone using just the number, like for a family member who keeps losing their phone and sometimes doesn’t answer. I’ve seen sketchy “tracker” sites but don’t trust them and I don’t want to do anything illegal. What are the real options (carrier, built-in services, consent-based apps), and what info would I need?
The only legal way is with the phone owner’s consent, using built-in services like Find My iPhone or Android’s Find My Device. Without consent, tracking is not possible legally and can be illegal.
