Setting up the Reliance Huawei EC-325 is relatively easy compared to that of its cousin the ZTE 880.  After you plug in your modem, running dmesg from the command line should show you something similar to that below.

[13834.424042] usb 4-2: new full speed USB device using uhci_hcd and address 6
[13834.604048] hub 4-0:1.0: unable to enumerate USB device on port 2

[13835.813641] usb 4-2: GSM modem (1-port) converter now attached to ttyUSB0
[13835.820376] usb-storage: probe of 4-2:1.1 failed with error -5
[13835.820394] option 4-2:1.1: GSM modem (1-port) converter detected

It detects it as a GSM modem which is OK.

To configure wvdial, type sudo wvdialconf It should show you that it has detected a modem at the end of the commands output. (If you don’t have wvdial do a sudo apt-get install wvdial -You need to be online to do this)

next edit /etc/wvdial.conf (sudo nano /etc/wvdial.conf) Make sure that in the line Modem = /dev/ttyUSB0 You replace USB0 with what wvdial detected in your case.

Then, Copy and paste the following lines into your wvdial.conf

Note: If you are copying and pasting, the quotes will get mangled and you will need to delete and renter all the quotes/comma’s

[Dialer Defaults]

Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
Phone = #777
Username = 9310xxxxxx
Password = 9310xxxxxx
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Set Volume = 0
FlowControl = Hardware (CRTSCTS)
Modem = /dev/ttyUSB0
Dial Command = ATDT
Baud = 460800
Stupid Mode = 1

Now replace the 9310xxxxxx in username and password with the Reliance number of your data card

Now you can connect by opening a terminal and typing in wvdial from the terminal. If you get any permission errors, try sudo wvdial. I haven’t managed to figure this one out yet. On some somputers it works without sudo, on this AMD64 Thinkcenter, I need to sudo to connect.
