Learn how to use the 3 way calling (also called as Multi calling) on your Samsung Galaxy S4. The 3-Way or Multi-Party feature allows you to answer a series of incoming calls and place them on hold. If this service is supported by the network, all calls can be joined together. You are notified of an incoming call by a call waiting tone.
Note: The Merge option combines all of the calls you have established with your phone (both active and on hold). Swap places the current call on hold and then activates the previous call.
