Solve : wifi vs 3g?

1.	Solve : wifi vs 3g?
Answer» on the tablets some offer only wifi others 3g. i am not SURE what this really means. if one buys a TABLET with wifi only can he still connect with the internet via modem? If so, what is the advantage of the built in 3g?Which tablets are you referring to? LET's take the iPad for example. Apple offers a Wifi iPad and a Wifi + 3G model. This simply means that, on the 3G version, you can subscribe to a 3G network. This will give you internet access wherever there is 3G coverage. The Wifi-only model means you can only use the internet where there is a wireless internet SIGNAL.
