Chinese Clones

If you own a GPS tracking unit made in China, please read following information.

Different manufacturers and sellers brand their devices under similar popular names (e.g. TK102, TK103, GT02A, H02 and other), so it is impossible to identify correct port and protocol for those devices just by the model name. Please carefully try all of the following common ports first:

  • 5001
  • 5002
  • 5006
  • 5013
  • 5015
  • 5023
  • 5036
  • 5093

Also check for following frequent issues:

  1. Device sends status information, but not GPS coordinates. Usually it happens with devices that use GPS103 protocol (port 5001). The solution is to send a command to the device to activate location reporting: fix060s***n123456 (where 060s is the interval between messages, *** tells the device to continue sending locations periodically and 123456 is the default password).
  2. Devices that use TK103 protocol (port 5002) send 12-digit device identifier instead of IMEI. Usually it consists of 11 last digits from IMEI plus leading zero. For example, if IMEI number is 123456789012345, the unique id would be 056789012345. The easiest solution is to register two devices, one with full IMEI and the other one with 12-digit identifier.

If you have tried everything above and your device still doesn’t work, try manually identifying the protocol. If even that doesn’t help, explore available support options.
