Cme error: 148

Legacy Open AT
1

Hi.
I’m trying to attach my modem (Q2426B) to the GPRS network and when I send the command AT+CGATT=1 the modem responds CME ERROR: 148. In the wavecom FAQ’s appears the possibles causes for this error like:

  1. When the GPRS services is not enabled on the SIM card.
  2. When the module is in a roaming and the currently selected PLMN does not support GPRS services for the HPLMN of the module.
  3. When the received signal strength by the module is very weak.

But my SIM card is already configured to work in the GPRS network and when I check the signal quality with the AT+CSQ command it seems to be OK.

My code is the following:

AT+CPIN=XXXX
OK

AT#GPRSMODE=1
OK

AT#APNSERV=XXXXXXXXX
OK

AT#APNUN=XXXXXX
OK

AT#APNPW=XXXXXX
OK

AT+CGATT=1
+CME ERROR: 148
+CGREG: 2
+CGREG: 0

How can I solve this problem???
Thanks to everybody
