If you own a no-name or cheap Chinese GPS tracking unit you must read the following information.

Different manufacturers and sellers brand their devices under similar popular names (e.g. TK102, TK103, GT02A, H02, and others), so it’s impossible to identify the correct port and protocol for those devices just by knowing a model name. If you have one of those devices please try all of the following ports:

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

Please also check for the following common issues:

1. The 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 the TK103 protocol (port 5002) send a 12-digit device identifier instead of IMEI. Usually, it consists of 11 last digits from IMEI plus leading zero. For example, if the 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 a 12-digit identifier.

If you have tried everything above and your device still doesn’t work, then your device is not supported.
