I'm trying to setup a Q2426B Wavecom modem to navigate using the GPRS channel.
Given the following sequence:
AT+CREG?
+CREG: 1,2
OK
AT+CREG=1
OK
+CREG: 2
AT+CREG?
+CREG: 1,2
OK
You can note that the device never registers on the network, its looking for a new carrier (+CREG: 1, "2"). Why is this? And which parameters should I change?
In the following commands:
AT +CGDCONT=1, "IP", "vox.internet","172.24.97.29"
OK
AT +CGQREQ=1,1,4,5,2,14
OK
AT +CGQMIN=1,1,4,5,2,14
OK
AT +CGATT=1
OK
AT +CGACT=1,1
+CME ERROR: 3
What is causing the failure? What should I change?
And in this:
AT +CGDCONT=1, "IP", "vox.internet"
OK
ATD*99***1#

NO CARRIER
Why isn't the carrier detected?
If I use the same SIM sith a WAP phone... it navigates without troubles... According to the carrier's technical support... it should work just fine with my PC as well...

How do you connect to the module? I do not know the module you're using.
However, the two last commands:
AT +CGDCONT=1, "IP", "vox.internet"
and
ATD*99***1#
seem to do the job. The garbage is probably the PPP-protocol. As your terminal don't answer, the connection is shut down after a little while. You will have to answer/implement the PPP-protocol, or use your PC (see below)
I would not bother to set the other parameters (AT+CGQxxx).
My way:
To use a GPRS-box as a modem I usually define a Unknown Modem (Control Panel - Phone and Modem Options i w2k)
and add the:
AT +CGDCONT=1, "IP", "internet" as extra initialization commands (Properties - Advanced)
Having the modem in place, create a new dial-up connection using the defined modem and use
*99***1#
as phone number (add username/password if necessary)
