Can I still use an unlocked iphone 5c without a data plan?

Thinking about ordering the iphone 5c online from Apple, it comes with a sim card already.
I don't want a data plan.
BUT can i still use the phone to text or access apps? Will i be able to use it over Wi-Fi? And does that mean I can't make phone calls?

Added (1). Oh, and it's the UNLOCKED iphone 5c****

If it's unlocked, you can go to your carrier and pick ANY plan you like. For example, a prepaid plan with some minutes and unlimited text for as little as $15 a month! If you don't want to use any carrier-offered services, yes you can download apps like Kik and Whatsappp for texting over Wi-Fi and apps like Skype for calls over Wi-Fi

Sure why not
