Hi, you don't give us a lot if info there.

What version of Ubuntu are you running and what version of Huawei dongle do you have and what program is it that recognize the dongle?

However I don't think you have to install or do much to get it working (that's only for Windows users), use the Network Manager in Ubuntu to set it up.

See this page for instructions:
https://help.ubuntu.com/community/NetworkManager0.7

See there is a tab for "Mobile Brodband", it's almost to easy.
