IP Communication (GPRS/EDGE/3G/HSDPA) settings
The GSM 3G supports third generation communication standard, including, from slowest to fastest:
GPRS (2G), EDGE (2.5G), UMTS (3G) and HSPDA (3.5G).
There is no configuration to select one or the other network; the GSM 3G will select the fastest available.
You have to choose either ‘GSM-Data’ mode OR ‘GPRS’ mode. It is not possible to use the
modem in both modes at the same time, but it is possible to combine GPRS mode and
sending of SMS (see below).
When selecting IP (GPRS, 3G, …),
TWinSoft
automatically adapts
Initialization and Operator Phone number
fields (see next).
If the connection requires a login, select
the
option ‘The server requires
authentication’.
You may receive a fix, dynamic, public of
private IP address, it depends on your
subscription; You don’t have to declare
the IP address anywhere.
Initialization: You have to update the initialization string with the APN (ask you GSM operator).
Replace in the string the apn with the URL you receive from your GSM operator.
Example with Mobistar: AT+CGDCONT=1,“IP”,“WEB.PRO.BE”.
PIN Code: If the SIM card you have inserted uses a PIN code, type it at the place of the letter n.
Example: with the PIN code 4896, you should have in the field: AT+CPIN=“4896”,
including the quotes.
If the SIM card you have does not require a PIN code, you can leave the field as it is or
erase it completely.
Operator Phone number: special number to establish the GPRS connection.
Typically, the number is *99***1#. Check with your operator and type it following the
command ATD.
Example with Mobistar, Proximus, SFR, AllIP, …: ATD*99***1#
