    In the phone settings, there should be a way to disable access to the memory card. Then set to modem mode.

    While I no longer have such a phone, I used to have to do that on my Sprint Instinct.

    I don't have any details or any more info other then to say that used to work for me.

    You may find umtsmon will work for this device. Yours may be in the list of supported devices:

    UMTSmon

    It may be necessary to google for more info on this - I've never needed it.

    Have a read of this guide. Its for Huawei devices, but the principles are the same.

    For devices that are not handled properly, there is a general manual method you can use to get the modem device exposed. First, open a terminal and become root with 'su - ' command. Then type

    Code:
    eject /dev/sr1
    If you do

    Code:
    lsusb
    you should now see your modem device with vendor and product ID codes (as far as I remember). You will need these in the following modprobe command

    Type

    Code:
    rmmod usbserial
    Code:
    modprobe usbserial vendor=0x**** product=0x****
    Hopefully you will now have a ttyUSB* device present.

    Code:
    ls -l /dev/ttyUSB*
    From there you can treat as a normal modem with wvdial, or configure with yast and use kinternet to dial.

    You need to be root first with

    Code:
    su -
    Then try the eject command.

    linux-2eoi:/home/njuguna # rmmod usbserial vendor=0x1edf product=0x6003

    Be careful with the commands you're typing. After

    rmmod usbserial


    you do

    modprobe usbserial vendor=0x**** product=0x****


    However, let me clarify, its not 'vendor=0x1edf product=0x6003'. That vendor code is for your mass storage device (built in). You need to be able to expose the modem device by this first

    eject /dev/sr1

    Then you should see /dev/ttyUSB* appear

    ls -l /dev/ttyUSB*

    You might like to try installing 'usb_modeswitch'. It will simplify the process of getting the modem working after plugging in. All you should need to do is verify that /dev/ttyUSB[0,1, or 2] exists. (However, I've never required this utility for any usb broadband modem devices, so you may have to google for more info on using it). It takes care of the storage/modem mode switching for you. Yo'd have to search and for and install the package via yast first. Then you run it with a command like

    Code:
    /usr/sbin/usb_modeswitch -v 1edf -p 6003 -d 1
    A guide on using usb_modeswitch for ZTE modem (same principles should apply to you):
