Dear NyeinChanAung
This is forum for users of GPS-Trace solutions for GPS tracking: Forguard, Ruhavik and Petovik.
If you are not using our application you need to contact the tracker manufacturer or the developer of the application you are using directly for help.
In case you want to use our applications for monitoring your vehicle, you need to create an account in our system. Please note that our application is free when used to monitor a single vehicle. For more information on how to get started with our applications, please visit https://gps-trace.com/en/how-to-start
What about APN, you need to check the details for setting up the APN with the mobile provider of the SIM card used in the tracker. Depending on the provider, this can be just the APN or also the APN username and password.
