It also lets you make calls from devices that are not on the same Wi-Fi networks as your phone (depending on your carrier) and also lets you make calls when your phone is switched off.

HOW TO HOOK UP TEXT MESSAGES ON MAC MAC
To receive calls on your Mac when it’s connected to a different Wi-Fi network, use Wi-Fi calling. Keep in mind that in order for you to receive calls from your phone, your devices have to be near each other and connected to the same Wi-Fi network.
Make sure you select the box next to Calls from iPhone.
Scroll down and click on “FaceTime” to see which account is enabled. On your iPhone, open up “Settings.” You should see your Apple ID at the top of the settings screen.
Make sure that both devices are connected to the same Wi-Fi network and that you’re signed into FaceTime and iCloud on both your Mac and your iPhone using the same Apple ID. Make sure your Mac is toggled on to receive text messages.
