why the app keeps saying there is no data?
1.Pls check if you insert the sim card correctly first.
2.The sim card you installed in the device is incompatible. The tracker support the GSM network.
3.If your sim card compatible with GSM , but there is no date
You didn't remove off the PIN code of your sim card. Put the sim card in your mobile, turn off the PIN code, then insert the sim card into the tracker again.
4.If you already turn off the PIN code, yellow LED still blinking fast -- it's the APN set problem, your sim operator APN not in our server list, there is the SMS command to set APN:
APN setting: “APN#parameter#account#password#”( if there is no account password, don't need to fill in. )(For example, there is a Holland Mobile APN is: KPNMobile, text message: APN#KPNMobile#)Text this message: APN#parameter to the sim number in the tracker, will reply you a message: set successfully.
