STARTING TWIG TRACER

Twig Tracer is a special application for real time monitoring and viewing movements and positioin of e.g. your partner or Twig Locator device.

With Twig Tracer you can, when requested, communicate your exact position to other people. You can also follow-up the movements of your partners who are listed as targets in the application. You can request position, tracking and area tracking of the selected target(s), and view your own as well as your targets' position on map. In addition, you can configure the GPS mode of a selected target device.

Twig Tracer targets can be any GSM devices with

GPS positioning and support for MPTP commands, such as another Twig Discovery phone, or other Benefon GPS-GSM devices.

Note that not all commands might not be implemented in all devices.

To enter the application, press
