Siemens-Sk65 udev script for GPRS

When I use GPRS some times my phone move to ttyUSB0 to ttyUSB1 and it disconnect me.

For the details doc: click here

I just add this in my udev.rules

KERNEL=="ttyUSB*", BUS=="usb", SYMLINK+="siemens-sk65"

then in my wvdial.conf

Modem = /dev/siemens-sk65

example:
