1-Way Voice

1-Way Voice helps locate a missing person indoors where GPS is ineffective. It is also used for well-being checks.




The Primary Guardian (person who completed the purchase) can edit which Guardians are authorized for calling the device.


The AngelSense subscription includes 60 free minutes. Typically caregivers do short well-being checks and the 60 minutes are more than enough. Additional minutes can be purchased in the AngelSense Store, and these minutes never expire.


Some schools require that the voice feature be disabled during school hours due to privacy concerns or school policies.


In order to activate the 1-Way Voice feature from your AngelSense app to the AngelSense GPS device:



  1. Go to the Voice Menu on the bottom of the app and click on “1-Way Voice”.

  2. The popup checks that you want to make a 1-Way call and to be sure to use the authorized phone number to call the device. Select ‘1-Way Voice’.

3. The telephone dialer will appear, displaying the device’s phone number. Start the call just like a regular phone call.

4. The device will not ring out loud and will automatically answer the call.

*The Watch screen does not show that a call is incoming or that a call is in progress.



  • The AngelSense GPS device picks up on speakerphone automatically, and 1-Way Voice mode begins.
  • During calls, the application does not receive GPS updates. If you are listening throughout the entire transit, the system will miss the transit.
  • Voice quality greatly depends on where the device is attached and the ambient noise. Often, background noise makes it difficult to hear, but you can usually understand.
  • Excessive calls will drain a lot of power from the battery. Each listening hour uses 2 hours of battery life.
  • You can use 1-Way Voice to identify their surroundings of an indoor place (see how)
  • Only the authorized phone numbers are allowed to call. You can turn on and off authorization as needed in order to authorize other users.
    • GPS 4 and Watch: up to 10 authorized phone numbers at one time.
    • GPS 1, the limit is 2 authorized phone numbers.
