    Hello,
    The shield doesn’t support calls. But you can receive SMS. Please check AT commands guide for details.

    Hello Saeed

    Thank you for the answer
    but why when I dial from my phone to the modem
    and then write ATA on the rpi
    the phone opens the Connection like the modem answered.

    Hi,

    It will receive(as you can send AT commands) the call but you will not get any voice support since the voice data pins are not connected.

    Hello Saeed

    than I don’t understand why I do not get the call confirmation.

    do I have mistake with the USB number I am using.

    for me USB4 is the port to send and receive the AT Command.

    Hi,
    I can get 4 ttyUSBx options

    /ttyUSB0
    /ttyUSB1 Receives GNSS/GPS data
    /ttyUSB2 Sends AT command when connected to PPP
    /ttyUSB3 connects PPP

    Is there any other device connected to your Raspberry Pi?

    Hello Saeed
    Yes I have USB HUB connected to the RPI
    and on the HUB I have USB GPS receiver
    USB WIFI, USB Keyboard and Mouse,
    and the Quectel EC25-E modem.

    USB keyboard and Mouse is not going to cause any problem.
    Could you try Quectel ec25 + base shield alone first?
