Step 3: Get Instant Position (SMS)

Use your phone to send the SMS command “G123456#” to the tracker’s SIM number (or call the tracker’s SIM number directly).

You will receive a reply with a Google Maps link, latitude/longitude, battery level, and device ID—click the link for the exact location.

Step 4: Start online tracking

Step 4.1:Download the WINNES GPS app (iOS/Android) or visit www.mytkstar.net to log in and track in real time.

4.1.1 Device ID Login:For single tracker use

Enter the Device ID (on the tracker’s back cover) and the default password(the last 4 digits of the device ID or 123456).

4.1.2 Login by Username: For multi-device users (register via "Sign Up")

Step4.2 APN Settings (Required for App Tracking)

Note: If the tracker is online in the app, APN configuration is NOT  required. Skip this step.

If the device status shows “Not enable”, please set the APN.

4.2.1 Find the APN information

Check your carrier’s APN parameters.

You can find this information by:Visiting your carrier’s official website, or Inserting the SIM card into a mobile phone and checking: Settings > Mobile Network > APN

4.2.2 Set the APN

Using your own phone, send these SMS commands to the phone number of the SIM card inside the tracker.

Only enter the parameters required by your carrier. (some carriers only need APN name, with no username/password).

Note: There must be a SPACE between "123456" and the parameter  (Example: apn123456 mobilenet)

For examples：

US SpeedTalk SIM Card, only the APN name is required (no username/password).

Send the single command: apn123456 mobilenet

For UK Vodafone SIM Card, the APN name, APN username, and APN password are required. Send these 3 SMS commands:

apn123456 pp.vodafone.co.uk

apnuser123456 wap 

apnpasswd123456 wap

IMPORTANT: After the APN settings are successfully configured, remove and reinsert the SIM card to reboot the tracker. The APN settings will take effect after the device restarts.

2. SMS Positioning & Core Commands

2.1 Instant GPS/LBS Position

2.2 SMS Reply Data Explanation

GPS Position Reply (Flashing Blue Light)

● lat/lon: Latitude/longitude (exact GPS coordinates)

● Spd: Device speed (km/h; 000 = stationary)

● T: Tracking time (factory default:

GMT/UTC 0; set your timezone in Section 3.2)

● bat: Battery level (10%–100%; alert sent when <20%)

● ID: Device ID (for app/web login; found on the tracker’s back cover)

LBS Position Reply (Solid Blue Light): Indicates the device is indoors and using cell tower signals; accuracy is lower than GPS.

lac:27a4 1223 T:24/09/15 15:17 bat:100% ID:2015070203

Last:T:25/09/15 03:04 [Google Maps Link]

● lac: LBS cell tower data (approximate position)

● Last:T Time of the last valid GPS position (Maps link shows this GPS location)

3. Advanced SMS Settings

All settings take effect immediately after the tracker replies “ok”. Use the following commands to customize alerts and device behavior.

Note: Leave one space between the 123456 and the parameter (such as a phone number or speed value).

3.1 Authorize Admin Number (Required for Security)

Important: Only your authorized phone Admin Number can control the tracker and receive security alerts.

Example: admin123456 +44XXXXXXXXXX(Note: Replace the example with your actual mobile number. Ensure you include the country code, such as +1 for US or +44 for the UK)

● Alert Notifications: Once set, this number will automatically receive SMS alerts for Low Battery, Overspeed, and Vibration (Shock).

3.2 Timezone Setup (for SMS Replies)

Important: The WINNES GPS App automatically syncs your local time—no setup is needed for App tracking. Use these commands only to adjust the time shown in direct SMS location messages.

Example (UK winter time): timezone123456 +1

Example (US East): timezone123456 -5

3.3 Overspeed Alarm (Shock Mode Only)

Receive an alert if the tracker exceeds a specific speed (km/h). The alarm is sent every 5 minutes until the speed drops below the limit.

● Alert SMS: speed alarm! (sent to admin number)

● Note: Use 3 digits for the speed (e.g., 050, 080, 120).

3.4 Vibration (Shock) Alarm

Receive an alert when the tracker detects movement or a shock. After enabling, the tracker must remain completely stationary for 5 minutes to "arm" the sensor. If it moves before 5 minutes is up, the alarm will not activate.

● Alert SMS: sensor alarm! (sent to admin number)

2.5 Factory Reset

Use these commands to clear settings or start fresh.

4. Troubleshooting

All common issues can be solved with simple checks—always start with the SIM card and power supply (the most common causes of malfunctions). For technical support, email support@mytkstar.com with your Device ID and a brief description (or photo) of the issue (response within 24 business hours).

Q1: Why haven't I received a text message reply?

Possible causes and solutions:

• PIN Code: The SIM card PIN code is not disabled. You must remove it before inserting the card into the tracker.

• Incorrect Insertion: The SIM card is not inserted correctly or is not detected. Remove it and reinsert it properly.

• Incompatible Card: Your SIM card is a "data only" type (IoT/M2M). Use a card that supports SMS and data.

• Weak Signal: The cellular signal is insufficient. Move the tracker to an open area, preferably outdoors.

• Insufficient Credit: The SIM card no longer has sufficient credit to send SMS messages.

• Messaging App: Only use your phone's standard SMS app to send commands (no imessage, etc.).

• Device Off: The battery is empty or the device is powered off. Charge it and check that it is turned on.

Q2:Why does the App show "Not Enabled" or the tracker replies with correct location via SMS, but APP location in China?

This usually means the APN is not configured correctly. Even if the tracker responds to SMS messages, it needs the APN to send data to the app.

Solution: Please repeat Step 4.2 APN Settings to configure your carrier's APN.

Q3: Why does the App show "Inactive"

The "Inactive" state can be caused by 3 main factors:

1) Insufficient GPS signal: The device is in an area where the signal is blocked or disrupted.

Solution: Move the tracker to an open outdoor area.

2) Sleep mode: The device has entered power-saving mode.

Solution: Wake up the tracker by physically moving it or sending it an SMS command.

3) APN settings: An error in the network configuration.

Solution: Check and reconfigure the APN settings if necessary.

Q4:Why am I not receiving alarm notifications from the app?

If your tracker is active but you aren't getting alerts, check the following:
