The CAREU UCAN Vehicle Tracker communicates with your control center by either
SMS or GPRS (TCP/UDP). Before the device is installed into a vehicle, communication
parameters should be set.

1. SMS Configuration
Use AT$SMSDST command to set a SMS control center phone number or short code.
For example, if the SMS control center phone number is [phone], the
AT$SMSDST command to be issued into HyperTerminal should be:

AT$SMSDST=[phone]

OK

Then you can try to use cellular phone or SMS gateway to send a SMS message to the
CAREU UCAN device. Send a SMS message -->"AT$MODID?"
Device will response:
$MODID=101000001

OK
