Not being able to use my USB modem was the one thing keeping
Karmic Koala (9.10) from being my favorite
Ubuntu to date.
Thanks to the diligence of the people behind this open source, free OS, recent updates enabled me to use my Huawei E1552 USB modem (
Globe Tattoo prepaid) to connect to the Internet.
1. Upgrade linux-headers to 2.6.31-14 or to the latest kernel. You can do this via the terminal or the Synaptic Package Manager, or the Update Manager. If you don't want to mess around with the terminal that much, I recommend using the Synaptic Package Manager, which can be found at: Application Menu-->System-->Administration-->Synapti
c Package Manager.
Before I did this, Karmic already recognized my modem and I was able to set up a connection profile via NetworkManager. However, I could never really connect to the Internet. The attempt to connect kept failing at authentication.
2. Install the linux-backports-modules-generic package and gnome-phone-manager (for sending and receiving SMS).
3. Restart your computer.
4. Plug in your Tattoo Huawai USB modem.
5. Right click NetworkManage, select Edit Connections.
6. At the "Mobile Broadband" tab, select Add. The wizard to set up a mobile broadband connection appears.
Select Huawei from the device dropdown, select Philippines as your country, click on Globe Telecom as your provider. Leave the "Select your plan" dropdown as is, click apply. The Edit connection window appears: change the APN from "internet.globe.com.ph" to "http.globe.com.ph" (do not include quotation marks in typing), click apply. Tadah!
Click on NetworkManager, select your Tattoo account and you're all set. You'll know you're connected if your modem's light stops blinking and is just a steady blue light.
Note: Sometimes the connection can be woozy due to signal strength. If you find you can't connect, try and try again. If a popup appears saying the Huawei connection needs a password, ignore it -- keep on tapping "Enter" on the keyboard (to leave the field blank and say it doesn't have a password) until the window disappears and you're able to connect to the network.
7. You'll find the Phone Manager application in Applications-->System Tools. You can use this to send and receive SMS via your Tattoo sim and modem.
To check how much load you've got left, run Phone Manager. It'll appear in your status bar. Right click on it, select Preferences and click on the "Connection" tab. Select "Other port" and type any one of the following, try and see which one will work: /dev/ttyUSB0 or /dev/ttyUSB1 or /dev/ttyUSB2 -- /dev/ttyUSB2 worked for me. Click on Close.
Click on Phone Manager again, and a send SMS window will appear. In the Recipient field, type "222", then in the Message field, type "BAL" (don't include quotation marks), then send. A message will arrive telling you how much load you've got left.
