Using USB stick in Ubuntu

3G protocols allow wide area cellular communications that include not only cellphone voice transmission but also integrated broadband internet connections. This can be integrated into a single device, or communications can be received through an EVDO adapter. Examples of 3G radio interfaces include Mobile WiMax, CDMA-2000, TD-CDMA, EDGE, and DECT.

Virgin Huawei e169

See the Ubuntu forum solution:

sudo gedit /etc/ppp/options

Then find the line that says:

#-chap

and uncomment it (delete #)

-chap

this disables CHAP authentication .

I also had to change the APN to VirginBroadband instead of VirginInternet which was the default, and now it's happy.

Other settings are as follows:

Number *99#

Uname <your virgin username>

PW <your virgin password>

This will let you use your USB Modem stick for surfing the internet.

Sprint

Sprint EVDO cards can be used most easily through KPPP. For instructions, read the Sprint Mobile Broadband Setup Guide from its official website.
