Does the iPhone 6 require internet for it to buy it? Or can you buy it without the internet?

Ok, so my dad's going to buy me a new phone as a reward for getting into this good school. I want to get the iPhone 6, but he says that the iPhone 6 MUST HAVE internet and that we can't afford that. Is this true, do you need to buy the iPhone 6 with internet?

All smartphones require data plans (aka internet).
