Quick User Guide
The configuration of the tracker is very simple, you just need a little patience. It works through sms commands
which the user sends the device from the own mobile phone number. It can also work through the app or web
page after necessary initial SMS configuration.
1. Prepare a SIM card
The tracker works thanks to a sim card which is put inside the device. Please be assured it has got sufficient credit
or a promotion, as it uses sms, calls and a little but necessary quantity of data traffic (about 100mb per month). Be
assured that the sim supports the GSM, GPS, GPRS, internet 2g networks, sms and calls. Ask your most trusted
company for eventual promotions about sim cards for home alarms or security systems.
2. Disable the PIN code
Insert the sim in a smartphone to deactivate PIN, answering service and call transfer. Get from the network
settings the APN information of your company (address and eventual username and password) or get it from this
address: http://wiki.apnchanger.org/Main_Page
3. Insert the SIM card
Go to an open space. Insert the sim in the tracker. This will shut on showing blue and yellow leds.
4. Setup the admin phone number
Set the admin number (your personal cellphone number) sending SMS to the SIM in the tracker:
Command: admin123456+space+your number (eg. admin123456 7894561230).
Reply: admin ok
You can now send command G123456# or call the tracker to soon receive a sms containing information about
latitude, longitude, date, time, tracker battery status and a google maps link which shows the tracker’s actual
position.
5. Setup the APN
As the device has to be connected with GPRS network before send location or alarm information to the APP
or Internet, APN settings must be done before using APP tracking or webpage tracking.
Please setup APN according to this example. Information should be replaced with those of your tracker sim
company
For Tesco Mobile SIM card in the UK, we got APN information below.
APN name: prepay.tesco-mobile.com
APN username: tescowap
APN password: password
Send SMS below to set APN
1. gprs123456
2. apn123456 prepay.tesco-mobile.com
3. apnuser123456 tescowap (no need to send if APN username is empty)
4. apnpasswd123456 password (no need to send if APN password is empty)
Now the blue and yellow leds should flash, indicating that the tracker receives gps and gprs signals correctly.
6. Install and login the mobile APP

On Android: Search “TKSTAR GPS”in the Google Play Store
On Apple iOS:Search “TKSTAR GPS”in the Apple APP Store
After download and installed the APP, input the below information for login.
Select “Log in by IMEI/ID”on the bottom of login screen
Server: www.mytkstar.net
ID: can be found on the back side of device
Password: 123456
7. Now you can fully use the tracker easily via the mobile APP, webpage and SMS command.
