Using the Wavecom Fastrack M1306B GSM Modem and the Intercel SAM Modem.
A GSM modem is just like any PSTN modem you may be familiar with, except it
communicates via the GSM mobile phone network, rather than the Public Switched
Telephone Network (PSTN).
SIM Card
The GSM modem must have a SIM card installed, the same way your mobile phone has a
SIM card. However you can’t just use a standard mobile phone SIM card, you must have the
card “Data Enabled” – that is you must contact your mobile phone network provider and
specifically ask them to “Data Enable” the card. (In Australia the Telstra contact phone
number is 1300 131 816.)
Wavecom Fastrack :
Push the eject button shown, to make the SIM
card holder pop out.
Put the SIM card into the SIM card holder as
shown, and insert the SIM card holder back into
the modem.
Intercel SAM :
The SIM card fits into the rear of
the SAM modem – so the modem
must be unscrewed from its
mounting, the cover removed
from the modem, the SIM card
inserted and the cover replaced.
Connect the antenna and apply 12V DC to the modem.
LED Indicator
Both the Wavecom M1306B and Intercel SAM modems have a LED indicator that flashes as
follows :
LED Steady
=> Not registered with network
(No SIM card, no signal, no PIN)
LED Slow Flash
=> Registered OK but not connected
LED Fast Flash
=> Connected and communicating
