How to connect to Navixy server

TopFlyTech T8603 is tightly integrated with this software platform.

Activation process

Automatic activation (recommended)

The software platform supports automatic device activation by applying APN settings, server address and port, as well as recommended tracking mode though the SMS channel. Normally you don’t need to configure anything manually. Just install the SIM card, switch the device ON and make sure it is located in the place with good GPS signal reception.

When you activate a device, the following SMS commands are sent from server to device:

SMS command from
Server to Device
SMS reply from
Device to Server
APN,0000, <apn_name>,<apn_login>,<apn_pass># <IMEI>,SET APN OK,APN:<apn_name>,<apn_login>,<apn_pass># Set up APN name, login and password
IP,0000,,47744# <IMEI>,SET IP OK,IP:,47744# Set up server address and port


Some parameters will depend on your cellular network operator or your tracker:

  • <apn_name> – APN name
  • <apn_login> – APN login
  • <apn_pass> – APN password
  • <IMEI> – Device IMEI (15-digit number, can be found on the device itself)


As soon as these commands are executed the GPS tracker will connect to the server, and the rest of configuration process will be done via GPRS channel.

Important notice:

  • Do not set any password on the device (by default: “0000”)
  • Do not set any manager numbers prior to the device activation
  • Do not set the Time zone, it must be UTC+0h as per default
  • Do not set any pin-code to your SIM card

Manual configuration

If you experience issues with the SMS delivery from the platform to device in your country, you can setup device manually by sending the above list of commands from your mobile phone.

Default settings
