SIM PIN
Telstra SIMs have a PIN set by default, so if you did not specify it, then your
SIM card most likely has one. To disable the PIN you need to put the card into
a normal digital mobile phone and select the security menu. Exact key presses
will depend on the mobile phone used but from this menu you should be able
to disable the PIN. Alternatively the following command can be used to disable
the PIN: AT+CLCK=”SC”,0,”XXXX” where XXXX is the pin number. The
quotes are required.
14.1.8
CSD Data Service
If the modem needs to send or receive calls, it will need Circuit Switched Data
(CSD) enabled.
This will be a separate number to your voice number. If you only have one
phone number for the phone then it is most likely the voice number. Check
with your service provider to enable the data service using Bearer Code 2620 –
see Section 3. This is the number that the modem must be called on. If you
have difficulty getting a data number activated on your SIM, contact Campbell
Scientific.
14.1.9
GUI Issues
If the Intelimax GUI becomes unresponsive or does not appear to detect the
modem when attached, restart the software. This fixes most issues.
