First time I use my Ubuntu I was so confused of how I can connect my Ubuntu to Internet. Then for several weeks I let my Ubuntu installed without touching any programs! I had a CDMA modem before and I always connect to Internet in Windows operating system.
Then, I began to try how had connecting to Internet in Ubuntu is. Finally, by simple way I can connect my Ubuntu! These are what I do to connect.
Connecting via GSM/CDMA Modem
I use ZTE CDMA MG1880 Modem with Flexi card plugged. Register your card to your operator before using. Remember your username and password. Write in note if necessary.
Plug your modem into USB socket and until indicator light on the modem device is on. Open your terminal and type (the $ and # mark is only a privilege indicator)
$ lsusb
It displays devices plugged in our USB socket. Here is my result,
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 005: ID 19d2:fffe ONDA Communication S.p.A.
Bus 004 Device 003: ID 0458:003a KYE Systems Corp. (Mouse Systems) NetScroll+ Mini Traveler
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 1058:1010 Western Digital Technologies, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
In my case, ONDA Communication is a factory of my modem. It means that my modem is recognized without installing any modem driver.
Then, at Main Menu go to System > Preferences > Network Connections to show this dialog
Select Mobile Broadband tab then click Add, it will show
Select your device. In my case, I use ZTE CDMA Tech then click Forward
Select your country. I select Indonesia, then click Forward
Because there is no provider listed, I enter my provider manually. You can type whatever you want. I type "Telkom Flexi" as an indicator that I use Telkom Flexi operator. Click Forward.
Creating connection list succeed. Then, we are to edit the connection we just create.
Enter your username and password you received from your provider. Then, click Apply. The connection is ready to use
The dialog above shows that I gained to create a connection named "Telkom Flexi connection 1". Okey, I will use it to make my Ubuntu connected to Internet. To do that, I click a network connection icon indicator located at top-right corner of Ubuntu desktop.
Just click Telkom Flexi connection 1 and Ubuntu is connected!
it indicates "connection process"
and it indicates "Connection Established" !!!
If you want, there is an application that can be a user interface to ZTE CDMA modem named "Cross Platform UI" It's free and easy to install. By this application you not only can connect your computer to Internet but also send-receive text message and doing voice call. Download here.
