Try this package:
https://dl.openrb.com/pkg/usb-modeswitch...9_imx6.ipk
https://dl.openrb.com/pkg/usb-modeswitch...9_imx6.sig

Install through System config > System > Packages > Add Package.
Reset your modem after installation.

Thanks for the fast answer.

i have installed the package. But no change the modem do not change the usb mode. After a reboot the device is only found as a USB Mass storage device
   

If i unplugged the device and plugged in again
   

After uninstall the package and reboot
   

I am happy about every solution.
