If it's in a mode which attaches as umsm, yes you need to look at ppp(4) and pppd(8), there are also some examples in umsm(4)'s own manual. I don't know this particular device, but in general these devices have several modes - the modem-like mode used by umsm, and a mode that presents as an ethernet interface (cdce or urndis), if it's in that mode then it would show in ifconfig and you would just use dhclient. It looks like you can switch modes on/off on a Huawei with an AT^U2DIAG=(something) command on the serial port (takes effect after replugging the device) but there doesn't seem to be much good documentation of the values to use. From ethernet mode it looks like the Huawei dongles have an internal web page that allows switching back to 'modem' mode.
