APN setting EG25-G

Hi!

I’d like to know how is the process to set up de APN in a EG25-G modem. I’m using SIM cards that only require APN (without user and password). In that case I use the AT+CGDCONT command and the connection is successful.

How can I do it when I need to set up the APN with user and password? I know the AT + QICSGP and AT + QIACT, but when I try to use them the connection fails. Are these commands suitable for this modem?

Thanks.

Yes.
If we need to set username and password for the SIM card, we only could try the AT+QICSGP.
The CGDCONT cannot configurate the username and passwd.
