GPS Tracker Sim Card Fault Finding

Have you activated the sim card and inserted into the device? Does the sim have available credit not data only? What network are you using? Can you put the sim card in a phone and check it can make and receive calls SMS and has an internet connection?

When you call does it:
A) Go straight to answer phone? This mean the device is either turned off, not in a service area or the sim card is not inserted properly

B) Rings once then goes straight to answerphone? This mean the device is turned on and working but you may not have an available credit on the device. Remember the sim has to be not data only, it must have credit available for calls, SMS and data.

C) It says the person is unavailable or the service is disconnected? This means that the sim has not been activated properly. Please try in a phone and check that it can make and receive calls.


What APN do I use when not using the recommended Amaysim Sim Card?

Send the following message to the number of the sim that is in device depending on which network you are using.

Telstra: AS7777AT+APN=Telstra.iph,,;

Vodafone: AS7777AT+APN=live.vodafone.com,,;

Optus: AS7777AT+APN=yesinternet,,;


 Is the tracker still not live on the software?

If not, send me the phone number of the sim that is in the device, turn it on and tell which network you are using. 

I will then remotely communicate with the device and get it online for you. 

We will get this resolved ASAP for you. Can you please turn on the device, leave beside a window and the charger. Then send us the mobile number of sim that is in the device, The network you are using and the IMEI number that is printed on the device. We will do some remote diagnostics and get back to you.

Please send all information to info@ozsmartthings.com.au
