Basic GPS Settings
The GPS unit is controlled via SMS and basically has a small mobile phone inside it. Once you have
inserted the SIM Card you SMS the GPS unit from your mobile phone just as if you were SMSing a friend.
Depending on the command you send, the GPS unit will translate the SMS, perform the function and
send a reply to you via return SMS.
Note:
The SMS functions listed in this guide should be sent WITHOUT the quotation marks. We have
bolded the actual command to make it more obvious.
Important Note to save you on usage costs
– The GPS comes pre-configured with a server to send data
to. We don’t use this server as we leave it open to you as to which platform to use if you want to track
online.
By default the GPS will send a packet of data to the server each night which costs about 30c on Telstra
Pre-Paid and will quickly drain your credit. To stop this happening, send the command “gprson,0#” to
the tracker. This will turn off the GPRS (Data) connection. You can test if the data link is turned off by
sending “gprsset#” and reading the message it returns.
The Green light will be extinguished with the GPRS turned off but the device can still receive SMS
messages. To turn the GPRS back on again, simply send “gprson,1#” to the tracker.
Note: The above section was updated 3 October 2017 to use the gprson command instead of the fake
APN work around which was causing issues with some recent firmware versions.
Set SOS mobile number(s)
You can set up to 3 SOS mobile phone numbers that the GPS unit will keep in its memory. These
numbers receive notifications when certain events occur and are the only numbers that can call
the GPS unit to use ‘Listening Mode’.
Send an SMS with “
SOS,A,MobileNumber1,MobileNumber2,MobileNumber3#
” (Note, you
don’t require all 3 numbers, you could send SOS,A,0400123456# and it will set 1 number only).
If successful, the GPS will reply with ‘SOS Number X setting OK’
Remove SOS mobile number(s)
Send an SMS with “
SOS,D,MobileNumber1,MobileNumber2,MobileNumber3#
” (Note, again,
you don’t require all 3 numbers, you could send SOS,D,0400123456# and it will delete this
number only)
If successful, the GPS will reply with ‘SOS Number delete successfully’
You can also select an SOS number to delete using its position in storage (harder to remember…)
Send an SMS with “
SOS,D,1,2,3#
” (Note, again, you don’t require all 3 numbers, you could send
SOS,A,2# and it will delete the second SOS number only) – you need to know the order to use
this function.
If successful, the GPS will reply with ‘SOS Number delete successfully’
