Peter,
cut and paste is the last step(for copying ppp script ;P )
Before that you need to setup your system to recognize that modem.
First check if the idProduct is listed in your usbdevs. If not you need
to add it similar way like are other.
For example E3131 is added like that:
root at backup:/usr/src/sys/dev/usb # grep -Hr E3131 *
serial/u3g.c:   U3G_DEV(HUAWEI, E3131, 0),
serial/u3g.c:   U3G_DEV(HUAWEI, E3131_INIT, U3GINIT_HUAWEISCSI),
usbdevs:product HUAWEI E3131_INIT       0x14fe  3G modem initial
usbdevs:product HUAWEI E3131            0x1506  3G modem

Then recompile and install kernel and try if that helps. I'm not sure if
compiling u3g module is enough that's why I suggested whole kernel
recompiling.
