When this tutorial was created, I used the BackTrack distribution. And it should work on other Linux distributions too.
First, you need to download usb_modeswitch. If you already have an internet connection (with Wi-Fi, for example), you can simply run the wget command:
wget https://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.2.tar.bz2
After the download process is complete, extract usb_modeswitch-1.0.2.tar.bz2, which you just downloaded.
tar -xjf usb_modeswitch-1.0.2.tar.bz2
Go to the usb_modeswitch-1.0.2 directory and install:
cd usb_modeswitch-1.0.2; sudo make install
and you will get output similar like this:
[sudo] password for ditatompel:
mkdir -p /usr/sbin
install ./usb_modeswitch /usr/sbin
mkdir -p /etc
install ./usb_modeswitch.conf /etc
It can be seen that two files have been installed: usb_modeswitch and usb_modeswitch.conf. Edit usb_modeswitch.conf, which is located in the /etc directory.
sudo nano /etc/usb_modeswitch.conf
Add the following configuration, which is similar to ZTE AC2710 (EVDO) modem configurations by Wasim Baig:
#########################################################
## ZTE AC2726i (EVDO)
DefaultVendor= 0x19d2
DefaultProduct= 0xfff5
TargetVendor= 0x19d2
TargetProduct= 0xfff1
MessageContent= "5553424312345678c00000008000069f010000000000000000000000000000"
Then, open the wvdial configuration in /etc/wvdial.conf and edit the configuration file:
* I recommend always backing up your configuration before making changes.
sudo nano /etc/wvdial.conf
Add the following configuration:
[Dialer smart]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
ISDN = 0
New PPPD = yes
Phone = #777
Modem = /dev/ttyUSB0
Username = smart
Password = smart
FlowControl = CRTSCTS
Carrier Check = No
Baud = 9600
The usb_modeswitch and wvdial configuration has been completed.
Run usb_modeswitch from the terminal to change the USB modem product from fff5 to fff1.
usb_modeswitch
Then, the next step we need to do is detect the product ID of the modem we are using:
sudo modprobe usbserial vendor=0x19d2 product=0xfff1
Finally, run the wvdial command:
sudo wvdial smart
