WiFi Calling with iPad

If your both your Cellular Carrier and your calling plan support WiFi Calling, your iPad can make and receive calls independently of the iPhone - even when the iPhone is switched off, elsewhere, or using a different WiFi network. Not all carriers support full WiFi calling - and many Carrier representatives don’t technically understand or acknowledge its existence.

More information about Continuity and the relevant Cellular services can be found here:

In conclusion, if your Cellular Carrier and tariff support WiFi Calling, it is theoretically possible to configure WiFi Calling service for your iPad. After WiFi Calling is enabled and configured, your iPad can continue to make and receive cellular calls independently of your iPhone whilst connected to a WiFi network. Otherwise, if WiFi Calling is not available, your iPad can make calls via your iPhone (using Continuity) subject to the iPhone being turned-on and connected to the same WiFi network as your iPad.

I hope this information and clarification is helpful in understanding the capabilities of both your iPad - and if you have one, your iPhone.
