Ubuntu + Umobile

While I was searching for solution to get my Umobile broadband connected to the internet using Ubuntu OS last 2 days, I can see that a lot of people were also in my shoes. So I decided to explain in details how I get to overcome this problem sucessfully.

First of all, I'm using Ubuntu 8.10 but I think this should work for whatever version of ubuntu. Bare in mind, this solution is only for model E220 HSDPA modem.

1. Applications -----> Accessories -----> Terminal

sudo gedit /etc/wvdial.conf

Press ENTER & input your password if neccessary

2. gedit application will pop out end edit it with this

[Dialer Defaults]
Phone = *99***1#
Stupid Mode = 1
Modem = /dev/ttyUSB0
Username = user
Password = pass
ISDN = 0
New PPPD = yes
Baud = 1843200
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem

Save & Close..

3. Restart

4. Applications -----> Accessories -----> Terminal

sudo wvdial

Press Enter

----------------------------------------------------------------------

If u're getting this for ur last few lines, meaning that u are connected

--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Fri Apr 24 09:37:23 2009
--> Pid of pppd: 7864
--> Using interface ppp0
--> local IP address 10.21.3.71
--> remote IP address 10.64.64.64
--> primary DNS address 123.136.100.2
--> secondary DNS address 123.136.100.3

5. Final step.. Open your firefox..

Press File option and uncheck 'work offline' checkbox. You can now start surfing

If you're getting this error message

--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory
--> Cannot open /dev/ttyUSB0: No such file or directory

Plug off your modem and plug in back.. wait for 10 seconds and start redialing again. Everything should works fine..
