How to make calls and send messages on other Galaxy devices

The Call & text on other devices feature is a Samsung account-based service that forwards and synchronizes calls and messages between your Samsung devices. You can use your phone’s number to make and receive calls and messages on your other Samsung devices. Your Galaxy phone and tablet must be signed into the same Samsung account and the Call & text on other devices function of both devices must be on.

Step 1. Launch the Settings app, and then select Advanced features.

Step 2. Tap the switch next to Call & text on other devices to turn it on.

Or you can also activate Call & text on other devices on the Quick panel.

The connection will occur automatically. Now you can make and answer calls or send messages on your tablet.

When a call comes in, if your tablet is closer than your phone, just answer the call on the tablet. It's very easy to take calls with a tablet instead of a phone. When you see an incoming call on your tablet, simply swipe the green Answer icon to answer the call. You can also reject a call by swiping on the red Hang up icon, or to send a message to the caller or call back by swiping up from the bottom of the screen.

If you would rather talk on your phone, tap Pull call on the phone itself. This will end the call on the tablet and open it up on the phone.

Device screenshots and menus may vary depending on the device model and software version.
