Wi-Fi calling is self explanatory. It works when your network signal is weak and phone is connected to Wi-Fi. The phone uses your Wi-Fi signal instead to make (and receive) phone calls. The catch is you have to have an active promo subscription or postpaid account to use this, as your call is still "counted" by your network.
The iMessage thingy is RCS, which is its Android counterpart. That one you can use via Google Messages app.
