Please also check for following common issues:
- 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).
- 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 your SIM Card is not making proper contact in the GPS you will not get a response, if the steel case that keeps the sim card secure is bent contact is lost. Add a piece or two of sellotape to the back of the Sim to make it thicker. Of use a piece of paper above the case to wedge it down a little.
- Some GPS units take the SIM card the opposite way around.
- Make sure your GPS is comunicating via SMS and has data available before directing the GPS to TrackinT (GPS Software Server).
- Check that you have the correct port for the GPS when pointing it to the server.
