If you use Huawei E220, Ubuntu 8.04 OS, and you want to connect to Telkomsel Flash in Indonesia, you can *almost* connect using the manual method that they provided to you on Ubuntu help here (the manual section):

https://help.ubuntu.com/community/DialupModemHowto/Huawei/E220

The auto-detection tool wvdialconf does detect the modem if you are using Ubuntu 8.04. However, when you enter “wvdial” it will fail as you will have no way to supply it with user name and password, because the Telkomsel Flash system does not use user name and password!

Fear not. Just enter anything in both fields (I use ‘telkomsel’ in both fields just for the heck of it, but anything should and will work just as fine). Then go on to dial using “wvdial” again. You should get connected now (and on the unlimited connection, it is much easier to use wvdial than Telkomsel’s dialer software on Windows. You don’t even need to press Enter repeatedly to retry connecting, if you can’t get in the first time. This is caused by wvdial not having any time-out feature as the Telkomsel Flash dialer does; it simply waits until it gets connected, even though the servers required for handshaking are not responding!)

P.S. Hmmm… this gets me thinking, why does it still work even though we’re not being authenticated (at least for the unlimited Telkomsel Flash package)? Because the handshaking is probably not used! Then why is the PAP/CHAP routine still embedded in the modem? We can probably get rid of the authentication setting on Windows in order to guarantee logging in EVERY TIME that “Connect” button is pressed. DISCLAIMER: This is just a theory, I haven’t verified it for fact yet. I’m just thinking out loud.
