PhoneTrack SMS lets people you trust locate your phone with a text message. No internet, no account, no cloud and no data plan. This phone tracker works wherever you can receive a text.

HOW IT WORKS
An approved contact texts your keyword. Your phone texts back its GPS coordinates and an OpenStreetMap link. They don't need the app and there is nothing to sign up for. For regular check-ins they can subscribe to updates every few minutes, each showing how far and in which direction the phone has moved.

YOU STAY IN CONTROL

A new number that texts your keyword waits for your approval. Nothing is sent until you tap Approve; blocked numbers are ignored.
An optional PIN locks the app's settings and approvals, so nobody else using the phone can switch it off or approve themselves. Parents can set up a child's phone, approve their own number and keep the PIN.
No internet permission, no account, no tracking, no ads.

GOOD TO KNOW

Set location to "Allow all the time" so a text can start a reply while the app is closed.
Turn off RCS chats for these conversations: Android hides RCS from apps, so those texts never arrive.
Needs Android 8.0 or later and a SIM that can send SMS.
