Sprint's 54 million subscribers who travel overseas need not worry any more on international roaming charges when they call their family and friends back home. The company last week introduced International Wi-Fi Calling service to call home at no additional costs starting with an over-the-air software update to Samsung Galaxy S® 4 with Sprint Spark.
Sprint which started offering native WiFi calling in US early this year at places without its mobile coverage, plans to expand Wi-Fi Calling with international calling capabilities to additional devices throughout 2014.
According to Sprint, the 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 when connected to a Wi-Fi network.
Wi-Fi Calling lets Sprint customers use voice and messaging services over existing home, office and public Wi-Fi networks.
