Kansas City is the 12th market that Sprint has deployed Spark in. The others include Austin, Texas; Chicago, Dallas, Fort Lauderdale, Fla.; Fort Worth, Texas; Houston, Los Angeles, Miami, New York, San Antonio, Texas and Tampa, Fla. By the end of this year, 100 markets will have the service, which will cover 100 million Americans. Besides faster speeds, Sprint Spark also features a stronger signal that penetrates buildings better than the carrier's regular LTE service. Sprint has also started to use HD Voice in the area. Sprint calls this a next-gen technology that removes background noises and enhances sound quality.
The devices that support Sprint Spark include the Samsung Galaxy S4, Samsung Galaxy S4 mini, LG G2, Samsung Galaxy Mega 6.3, Nexus 5 and the HTC One max will work with Sprint Spark. Soon, the LG G Flex will be added to the roster once it launches on Sprint.
