Where/how to put apk additional data of games iOS?

So i got a new iphone 5, but its 6.1.4 so can't jailbreak, n most importantly, I DON't HAVE INTERNET IN IT. So i use itunes from pc to transfer games BUT i can't download additional data in-iphone games.
like Fast n Furious 6, it needs network, then Nitro, Despicable me minion rush,(these r the games i need network so far), n i have very less idea on iOS devices cuz i used android last 3 years…
o i need infos like where can i get the additional datas, or do i need to jailbreak n stuff.
NOTE: the apps on my iphone is all legally paid on itunes(basically free app though. )
so if there's any way OTHER THEN usinng net on mobile, id like to check it out.
n please don't answer like "get a Wi-Fi its cheap" or "search around your home for free Wi-Fi", etc…

I'm sorry, but there really isn't a way. Even jailbreaking your phone won't get you free Wi-Fi. Downloading the additional data requirese 3G/4G/Wi-Fi. Even if you were to download the additional data you still need Wi-Fi or 3G/4G to keep playing the games that require it. Also how the heck can you download games on your iTunes then sync them onto your iPhone? Doesn't that require you to have internet in your house? And so if you have internet. Why not use it to download the games directly on your iPhone.

But overall you need Wi-Fi to keep playing the games that need it. So I would suggest getting games that could be played offline. I would recommend Injustice. It's an awesome game for people who love DC games ( That's where super heroes like Superman and Batman come from by the way ) Real Racing 3 is also awesome if you like racing games. Hope I helped.
