This release does not have a Play Store Description, so we grabbed one from version 4.0.00.33:
Make calls and send messages from your Galaxy tablet
Don’t you hate it when your phone starts ringing once you’re snuggled up and comfortable in bed? With the Call & text on other devices feature, you can make and receive calls on your tablet as long as it’s signed into the same Samsung account as your phone. You can also send messages. However, the connected phone will need to have active service.
Note: Call & text on other devices currently does not work with Verizon and AT&T phones and may not be available on all models from other carriers.
Note: If your Call & text on other devices version is higher than 3.3.00 these features have changed. In order to make or receive calls, both the tablet and phone must be using the same WiFi network. You can send and receive messages whether or not both parties are on the same WiFi network.

A20, A50, A32 5G, A42 5G, A52 5G
