Configure admin number in Sino GPS trackers (ST-906, ST-915)

You can set three authorise mobile numbers that can control your Sino GPS trackers (model: ST-905, ST-906, ST-915 and ST-925). Set an admin, i.e. control number, send this SMS command:

Number+pass+blank+serial
Sample: 04001234560000 1
Where, 0400123456 is your mobile number, 0000 is password, 1 refers to the first admin/control number.
When the tracker reply “SET OK” means the setting is ok.

Set admin number in a Sino GPS tracker

To check /view the admin number you can send an SMS command RCONF or rconf.
You can then set the second and third admin/ control number.

Now, how can we remove/delete an admin/control number if we incorrectly set it?

To remove / delete control number from your GPS trackers:
Send the following SMS command:

D101# (delete the first control number)
D102# (delete the second control number)
D103# (delete the third control number)

You can again send SMS command, RCONF or rconf to verify the number deletion.

See, admin number 2 is removed from the config.
