Please get the exact correct APN name from local SIM card provider. Take the tracker to a good signal place for operation and configure the APN for it as below:
| SMS Command Format | Reply | Example | Note |
|---|---|---|---|
| APN,ApnName,User,Password# | SET APN OK | APN,orange,orange,orange# | If the SIM card has APN user and APN password, then use this command. |
| APN,ApnName# | SET APN OK | APN,internet# | If the SIM card operator doesn't have APN user and APN password, then please use this command. |
Note: The APN information is very important; it must be 100% correct to match the SIM card of the tracker. If you configure the wrong APN, the tracker will reply "SET APN ok" but it will not get online!

6. Installation Recommendation
Where is the OBD interface?
Most of the car's OBD interface is located in A and B. A small part of the car will be in C, D, and E.
[Diagram Description: An image of a car's interior dashboard with areas A, B, C, D, E highlighted, indicating typical OBD-II port locations.]
| Area A | VW, Ford, Toyota, Hyundai, Citroen, BMW, etc./Most cars. |
|---|---|
| Area B | Honda, Lexus, etc. |
| Area C | Dongfeng Citronen, etc. |
| Area D/E | A few cars... |
7. Troubleshooting
| Type | Use |
|---|---|
| Unable to connect to tracking platform | Check the APN and settings. Check whether the data service of SIM card is enabled. Check the balance of SIM card. |
| Tracker shows offline | Check whether external power is still connected. Check if the vehicle entered network blind area. Check the balance of SIM card. |
| Unable to locate | Make sure the top side facing upward without metallic things shielded. Make sure it's not in an area with no satellite coverage. |
| Location drift | In areas with poor GNSS signal (tall buildings around or basement), drifting may happen. Check whether vibration happens around to trigger the accelerator. |
| No command reply | Make sure the command format is correct. The vehicle may be in a network blind area. Make sure the SIM card is well inserted and has SMS service. |
