It's a feat for 3 languages, and even when 4e was released and feats were essentially worthless, it was a weird option. There's only 10 basic languages in the game. Most starting characters have from 2 to 3. (2 is the default, but you can pick up another with your theme.)
4e doesn't have skill points, so that's not an option. You can learn new languages with a feat, as parts of paragon paths, or via items/ritual casting.
Telepathy is a popular way around it, too. :)
