Modern transport monitoring systems are becoming more accessible, and the device Tkstar TK915 is a prime example of an effective tracker with advanced functionality. This gadget allows you to track your location in real time, monitor fuel consumption and even control your car's engine remotely. However, to gain access to all features, you must complete the initial setup and activation of the SIM card correctly.
Many users encounter difficulties when starting up for the first time, since the factory instructions are often written in complex technical language or contain translation inaccuracies. In this guide, we will go through each step of preparing the tracker for work, paying special attention to SMS commands and server configurations. You will learn not just to turn on the device, but also to set up geofences, listen to your surroundings and block the engine.
It is important to understand that TK915 is a serious security tool that requires careful attention to installation details. Errors at the stage of entering APN settings or activating GPRS can lead to the tracker being “silent” on the server, even if the GPS indicator is on. Below is a step-by-step algorithm of actions that will help you avoid common mistakes.
⚠️ Attention: Before starting installation, be sure to check the polarity of the wires. Mixing up plus and minus when applying power can lead to irreversible damage to the tracker electronics.
Preparing a SIM card and activating GPRS
The foundation of any GSM tracker is high-quality communication. For Tkstar TK915 A Mini-SIM (standard) SIM card is required, although adapters are often included. The key requirement is to disable the request PIN code. If the card is new, insert it into a regular mobile phone, disable the PIN request in the security settings and make sure that there are funds in the account for data transfer.
After installing the card in the tracker and applying power, the device must register on the network. The GSM indicator will start flashing at a certain interval, signaling that it is searching for a network. Once the connection is established, it is necessary to activate the GPRS function, without which the transfer of coordinates to the server is impossible. To do this, send an SMS from the owner’s phone to the tracker number.
The command to activate GPRS is as follows: adminip123456 (where 123456 is the standard password, if it has not been changed). After successful activation, the tracker will confirm the action with a response message. The device is now ready to transmit packet data.
- 📱 Make sure that the Data Transfer service (GPRS/3G/4G) is enabled on the SIM card.
- 🔒 Be sure to remove the PIN code request before installing it into the tracker.
- 💰 Check your account balance to avoid blocking by the operator.
- 📡 Wait for the GSM indicator to flash steadily before sending commands.
APN setup: Internet access
The most critical stage of setup is registering the access point APN (Access Point Name). Without the correct APN settings, the tracker will not be able to access the Internet, even if GPRS is activated. The parameters depend on your mobile operator and must be entered as accurately as possible, respecting the case of letters.
To configure, send an SMS command in the following format: apn123456;point_name;login;password. Often a login and password are not required, then a space or an underscore is used instead. For example, for some operators the command might look like apn123456;internet;;;. It is better to check the exact data for your region with your telecom operator or in the table below.
⚠️ Attention: When entering the APN command, do not allow extra spaces. An error in one character will result in the tracker being unable to connect to the monitoring server.
Table of popular APN operators
MTS: internet, mts, mts|Beeline: internet.beeline.ru, beeline, beeline|Megafon: internet.gprs, gdata, (empty)|Tele2: internet.tele2.ru, (empty), (empty)|Yota: internet.yota, (empty), (empty)
After successfully setting up the APN, the GPRS indicator on the device body should light up or change its blinking pattern, which indicates the presence of an Internet connection. If this does not happen, try rebooting the device by turning off the power for 10-15 seconds.
| Operator | Access Point (APN) | Login | Password |
|---|---|---|---|
| MTS | internet | mts | mts |
| Beeline | internet.beeline.ru | beeline | beeline |
| Megaphone | internet.gprs | gdata | - |
| Tele2 | internet.tele2.ru | - | - |
Registration on the platform and server
To visualize data on a map, you must register the device on the server. Tkstar TK915 by default it is often configured for Chinese servers, which may be unstable or unavailable in your region. It is recommended to redirect the tracker to a local or global server, e.g. gps.ee or ru02.gps.ee.
The server and port are changed via SMS command: adminip123456;IP_address;port;0. For example, for the gps.ee server the command will be: adminip123456;gps.ee;8820;0. After sending the command, the tracker should reboot and begin transmitting data to the new address. You can check the status by sending the command status123456.
Use the command "over speed123456;120" to set the speed limit to 120 km/h. If exceeded, the tracker will send a notification.
After setting up the server, register on the web platform or mobile application (for example, ProTrack or TKStar). Enter the device IMID (indicated on the sticker) and the password you created. If all steps are completed correctly, the device will appear in the online list and you will see its coordinates.
Function control via SMS commands
Main advantage TK915 — the ability to have full control through simple text messages. You can control the device even without the Internet, while in the GSM coverage area. Below is a list of the most important commands that every owner should know.
To listen to the interior, send the command call123456. The tracker will automatically answer an incoming call on the first ring, allowing you to hear what is happening around the car. To disable this feature, send nocall123456. A command is also available to force the determination of coordinates: where123456.
adminip123456;server.ip;port;0
// Example: adminip123456;gps.ee;8820;0
An important function is battery monitoring. Team batt123456 will request a report on the charge of the built-in battery. This is useful for diagnostics if the tracker has stopped transmitting data when the external power is turned off.
- 📞
call123456— activation of interior listening. - 📍
where123456— request current coordinates by SMS message. - 🔋
batt123456— checking the charge level of the internal battery. - 🛑
stop123456— engine blocking (a relay in the circuit is required).
☑️ Check before travel
Diagnosis and Troubleshooting
If the tracker stops responding or is displayed “offline” on the map, it is necessary to carry out diagnostics. First of all, check the status of the indicators. If only the red power light is on and GSM and GPS are not active, the problem may be with the SIM card or antenna.
A common problem is the “flashing” of APN settings after updating the operator’s network. In this case, a complete reset of settings using the command reset123456 and re-configuring from scratch. It is also worth checking whether the money in the account has run out, since if the balance is zero, data transfer is blocked by the operator.
⚠️ Warning: When using the engine lock command, make sure the vehicle is parked in a safe place. Blocking does not occur instantly, but after stopping the engine.
If the GPS antenna does not see satellites (the GPS indicator does not light up or blinks slowly), check the quality of the antenna installation. It should be on a metal surface (roof) and have a direct view of the sky. Signal reception is not possible inside a metal garage or underground.
90% of problems with Tkstar trackers are related to incorrect APN settings or the SIM card being blocked by the operator due to lack of traffic.
Frequently asked questions (FAQ)
How do I change the default administrator password?
To change the password, send the command password123456;new_password. Remember the new password, as without it you will lose access to manage the device. The standard password is 123456.
Why does the tracker show coordinates with a large error?
The error may be caused by poor GPS reception (antenna inside the cabin, near metal) or the use of LBS (tower triangulation) instead of satellites. Make sure the GPS antenna is installed correctly and has a view of the sky.
Can Tkstar TK915 be used for motorcycle?
Yes, the device is protected from moisture according to the IP54 standard, which allows it to be used on motorcycles. However, it is recommended to additionally protect the housing from direct water ingress under high pressure washing.
What to do if the tracker does not send coordinates to the server?
Check APN and server settings. Send a command status123456 — the response SMS will indicate the GPRS status and the IP address of the server to which the data is sent. Compare it with what is required.
How often does the tracker send coordinates?
The interval depends on the settings. By default, this could be 10-30 seconds when moving and 1-5 minutes when sleeping. You can change the interval with the command upload123456;seconds.
