Sprint Samsung Galaxy S4 with Spark, receives update to support International Wi-Fi Calling
With this feature, Sprint customers with the updated Galaxy S4 can use Wi-Fi Calling, even when outside of the U.S. While overseas in over 100 countries, these Sprint customers will be able to call or text anyone in the U.S., the Virgin Islands, and Puerto Rico without having to pay for the calls, or having them count against their monthly allowance of voice minutes. Over the course of the year, other Sprint models that support Wi-Fi calling will receive the update that allows them to use this feature internationally.
Right now, 11 Sprint branded handsets can use Wi-Fi Calling such as the HTC One max, HTC One (M8), HTC One (M8) Harman/Kardon edition, LG G3, LG G Flex, Samsung Galaxy S4 with Sprint Spark, Samsung Galaxy S4 mini, Samsung Galaxy S5, Samsung Galaxy S5 Sport, Samsung Galaxy Mega, Samsung Galaxy Note 3 and the Sharp AQUOS Crystal (coming soon).
