Is there any calling apps that work without Wi-Fi?

I have a 5 Generation iPod. My parents can't afford an iPhone for me, and I can't afford one either. I want to call and text without Wi-Fi on my iPod. Is there any LEGIT and REAL apps that do this? If you don't have anything nice to say, don't say it at all.

-Thank you.

Kind of impossible it needs some kind of Internet or cellular connection in your case Wi-Fi is the only option think of it this way can a tv turn on without electricity

So… Do you expect it to travel through dirt?

No. Not a phone.
