In case the PIN code request of the SIM card was already switched off or you change later
to a SIM card with switched off PIN request you need to delete an earlier entered and stored
PIN code by insertion of
PIN number = 0 <Return>
.
For the protection against misuse and theft the inserted PIN code cannot be requested
Attention: Never change the PIN code arbitrarily. The PIN code is
send from the viasis to the radio modem after each modem power on
automatically. After 3 failing attempts the SIM card is locked and the
PUK code is requested further on.
In case the inserted PIN code is rejected check your provider infor-
mation first before you retry it again.
6.4.2.3 GPRS configuration
If you select “
3. Configure GPRS
” in the GSM/Email menu you will receive the current GPRS
configuration. The following example shows the configuration ex factory:
APN: not set
USER: not set
PASS: not set
ROAMING: off
Change (y/n)?
In case you answer the question
“Change(y/n)?”
with “y” for yes, the APN (access point net-
work), the related USER username and PASS pass code will be requested sequentially by the
viasis. Valid entries are up to 31 alphanumeric characters, but without question mark, colon
and double point. The text string must be ended with <
Return
>. Entering
<Return>
only will
skip the request and the setting remains unchanged.
Thereafter you can allow or deny roaming connections, what means connections made instead
of your service provider by another provider, which will bill the connections separately to your
provider. This is in common accompanied by much higher connection charges.
You may configure GPRS access by all viasis serial interfaces (RS232, GSM, Bluetooth and
USB). But only by using the RS232 connection the configuration is immediately tested and the
protocol is send to a connected terminal:
Configure ...

AT+CGDCONT=1,"IP","internet.t-mobile"
AT+QICSGP=1,"internet.t-mobile","tm","tm"
AT+CGATT=1
AT+QIMODE=1
AT+QIREGAPP
AT+QIACT
AT+QILOCIP
+IP: 100.76.160.156

In case of a problem or an error while establishing the GPRS connection the sequence above
ends with „
Error GPRS
“. If you configure by other interfaces as RS232 connection a direct
