Sprint has started rolling out a new over-the-air update to its Samsung Galaxy S4 devices that support Sprint Spark, enabling them to use international Wi-Fi calling features for the first time.

Sprint states:

"This new feature allows those traveling abroad with Wi-Fi Calling enabled phones to make and receive calls to friends and family in the United States, U.S. Virgin Islands and Puerto Rico at no additional charge while connected to a Wi-Fi network."

This new feature is supported in 100 countries. Sprint added that it will update more of its smartphones with this international Wi-Fi calling feature throughout the rest of 2014. What do you think of Sprint adding this feature to the Galaxy S4.
