We advice you to use the sim card like speedtalk, please make sure that the sim card have call sms service and data 

1.Why does the device show wrong position when the device is online in platform？  
1). No GPS signal ,but the device can get LBS location, should put the device on the window or outside to get GPS signal , the blue light is solid on in this situation, the green light flash  

 2.Why does the device can’t be on line ? 
1)  APN setting is wrong 
2) GPRS is off ( the green light is off or solid on ) 
3)  IP and port was changed by somebody 

When app shows offline, then need to set up the apn 
Firstly, Need to ask the carrier about the apn informtaion of the sim card in tracker 
Then send those command:
Gprs123456
Apn123456 apn name
Apn123456 apn username
Apn123456 apn password
Have a space after 123456 , don’t need to send last two commands if sim card don’t have username and password.

For Example: if you use the card Speedtalk 
Apn name :wholesale
Apn username:blank 
Apn password:blank 
Then you need to send the command:
apn123456 wholesale
Gprs123456

Package includes:
1 x GPS tracker
1 x USB cable
1 x user manual
