Well, it depends. Once you've decided to track their location by phone number, TrackPhone will send them a text message with a link they'll need to tap. What's in the message is for you to decide, so it's your call if you wish to hide your identity. But remember that if you choose to hide your name or write vaguely, they might be less willing to share their location. Clarity and openness in your message are key to finding where they are.
