Apple have been making Macs since 1984 and there have been numerous versions. There are numerous providers of 3G internet connections. The possible permutations are too numerous to individually explain. In general the provider may supply a USB dongle (configured in the Network section of System Preferences) that plugs into a Mac's USB socket to connect to a 3G Network, or the Mac may connect to a 3G phone via Bluetooth (configured in the Bluetooth section of System Preferences). Not all providers/accounts will allow such connections to their 3G network.
