There should be drivers built in to support the Huawei modems. I have and I'm still having some problems with the 3g connection since Ubuntu 9.10 with the Huawei E220 and Huawei E1550 modems. There may be problems getting the dongles to work from Ubuntu. I sometimes solved and got the modems working by unplug and plug back in workaround. Kubuntu 11.10 has sometimes connected with the Huawei E220 modem.
@Sleepy John (john-eyre) comment #13 "CODE sudo usb_modeswitch -v 0x12d1 -p 1003 -V 0x12d1 -P 1003 -R Then unplug and replug the dongle, and now it will connect." Solved the problem, this works perfect. Kubuntu 11.10 now connects with my Huawei E220: "Connected to Tele2 - Mobilt Bredband".
