When reading this user manual, you will notice that we have used "+" and
"space" between some words;
"+" between two words means they should be written together as one word and
"space" between two words means you should leave one character space
between two words.
e.g. : sleep+123456+space+shock this should be sent to the tracker as
follows;
sleep123456 shock
6.6 Authorization
You have to save your phone number as authorized user to be able to use certain
functions as movement alerts, sos alerts and reports. You can authorize up to 5
numbers. Authorization can be done in two different ways;
6.6.1 Dial the GPS-303’s number 10 times from your mobile phone and it will
register your mobile phone number as the authorized number automatically
6.6.2 Send SMS “admin+password+space+cell phone number” to set up an
authorized number. All the other authorized numbers must be set by the first
authorized number.
Example: admin123456 07776665554
Response: admin OK
Depending on your network and phone, the tracker may read your number in
internatonal format. If you notice that the GPS-303 doesn’t send you any alarm
notifications after or doesn’t respond to your calls with a location report after

9
setting yourself as the authorized number, try authorizing your number in
international format;
Example: admin123456 [phone]
Response: admin OK
6.6.3 Delete authorization Send SMS：“noadmin+password+space+authorized
number” to delete the authorized number.
6.7 SMS Text Message locating
If there aren't any authorized numbers set-up, GPS-303 will reply to all calls
with a location report. If there are authorized numbers set-up, only authorized
numbers will be able to receive location report from the tracker.
The SMS text message will include coordinates, current speed, time and date. It
will also contain a direct Google Map link for smartphone users.
*If you request your tracker's location and receive blank text message with no
coordinates or location information, this means your tracker has not established a gps
fix yet. Once it establishes a gps fix it will send another text message with the new
coordinates.
6.8 Interval Tracking
GPS-303 can send automatic location reports at set intervals. If SMS mode is
active, reports will be sent as SMS text messages. If GPRS tracking mode is
active, location report updates will be uploaded to the online tracking server.

6.8.1 Continuous interval tracking:
Send SMS “fix030s***n+password” to the GPS-303, it will reply the
latitude & longitude continuously at 30 seconds fixed intervals.
Note: Minimum interval setting is 10s.
Example: fix030s***n123456
Please note that you will not get a response for this message.
6.8.2 Smart interval tracking:
Please activate "Continuous interval tracking" before selecting this function.
Send sms command "distance+password+space+distance" to activate smart
interval tracking. GPS-303 will reply "Distance ok" and it will start uploading
its location at pre selected time intervals and distance.
Example: distance123456 0050
Response: distance OK
This means that distance is 50 meters; the number must be 4 digits. This will
configure the GPS-303 to send its location every 50 meters.
To set this function on live tracking mode: Set time interval first and then
distance interval, GPS-303 will locate upon the time and distance.
6.8.3 To Cancel auto-tracking: Send SMS “nofix+password” to the tracker
device to
cancel the auto-tracking (auto-reporting).
