How to use SmartBro Prepaid Kit on Linux (ZTE MF622 HSDPA USB MODEM)

Due to the typhoon that hit our area (Kalibo, Aklan), I was pushed offline, internetless for a week. As a recourse I was forced to purchase the SmartBro Prepaid Kit (ZTE MF622 HSDPA Modem).

Here's how I was able to use the SmartBro Prepaid Kit (ZTE MF622 HSDPA Modem) on my Linux dev machine (fedora 8) and should be applicable to other popular desktop linux distros.

I created two files as follows:

/etc/udev/rules.d/25-zte-mf622.rules containing:

ACTION!="add", GOTO="End"
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000",
SYSFS{idVendor}=="19d2", GOTO="ZeroCD"
SUBSYSTEM=="usb", SYSFS{idProduct}=="0001",
SYSFS{idVendor}=="19d2", GOTO="Modem"
LABEL="ZeroCD"
RUN+="/sbin/rmmod usb_storage"
LABEL="Modem"
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001",
MODE="660", GROUP="dialout"
LABEL="End"

/etc/smartbro.conf containing:

[Dialer Defaults]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init5 = AT+CGDCONT=1,"IP","smartbro"
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99#
Modem = /dev/ttyUSB0
Username = user
Password = pass
Dial Command = ATDT
Baud = 460800

To connect to the internet via the usb modem, simply invoke the following command on the terminal:

wvdial --config=/etc/smartbro.conf

To Disconnect, kill the process ID of the PPPD command called by wvdial or simply remove the USB HSDPA Modem.
