Does an iPhone 5 need Wi-Fi or can you just use the 4g data internet?

Does an iPhone 5 need Wi-Fi or can you just use the 4g data internet?

Anything you wish you can use

An iPhone all of them has the compatibility to connect to Wi-Fi. But it does need to me hooked up to a provider (i.e. Telus, Bell, Rogers, Virgin Mobile, etc.) be using Wi-Fi. When not in a Wi-Fi accessible area who can then use the 4g data plan if your provider has 4g available for iPhone 5 it probably does.
