    Default Message control using USB GSM modem

    After checking the sticky topic Modems that are tested by COPA-DATA for message-control I bought the Huawei E1550 – UMTS-Modem for sending messages. Accordingly the the mentioned topic, it should work, but I think I am doing something wrong.
    This is what I have in Device Manager:

    In Message Control/SMS Mesage, everything seems to be OK:

    But when I try to send a message, I get this errors in Diagnosis Viewer:

    So, please tell me, what did I do wrong?

    Thank you!

    Default AW: Message control using USB GSM modem


    I know that some modems need to have an initial connection established - e.g. the modem itself is working, but it has not dialed in to the operator network. Our test modem at COPA-DATA behaves like this as well.

    Try to start the modem software that was supplied with it one time, try to establish a connection and then quit the software again. That always is working for me

    best regards,
