Sprint also offers an unlimited data plan for smartphones on its LTE network
Sprint has launched its new 4G LTE network to 15 cities in the Atlanta, Dallas, Houston, Kansas City and San Antonio markets.
Sprint LTE network has gone live in Atlanta; Athens, Calhoun, Carrollton, Newnan, Rome in Georgia; Dallas, Fort Worth, Granbury-Hood County, Houston, Huntsville, San Antonio, Waco in Texas; Kansas City, and St. Joseph, Missouri.
The company which had launched its 4G service in 2008 in the country is also planning to launch a 4G LTE network for residents surrounding Waco, Texas.
Sprint Network senior vice president Bob Azzi said, "Sprint and our vendors have been deploying Network Vision sites all across the country for the last several months and we are thrilled to deliver our new network to our customers today in and around Atlanta, Dallas, Houston, Kansas City, San Antonio and Waco."
"This new network is performing extremely well and customers should find it consistent, reliable and really fast," Bob added.
Sprint plans to launch additional 4G LTE markets in the second half of 2012, which will be announced later this year.
By the end of 2013, Sprint expects to largely complete the build out of its 4G LTE nationwide network to reach 250 million people across the US.
The company said users will have average downlink speeds of 6-8 Mbps with peak speeds of 25 Mbps, and average uplink speeds of 2-3 Mbps and experience stronger signals and better video streaming capabilities on wireless devices.
Sprint has already launched five 4G LTE-capable devices for $199.99 each including the HTC EVO 4G LTE, LG Viper 4G LTE, Samsung Galaxy Nexus, Samsung Galaxy S III and Sierra Wireless 4G LTE Tri-Fi Hotspot.
Sprint started offering 4G services based on WiMax technology in 2008, being the first national wireless carrier in the US, the company said.
The company has joined the 4G LTE party, but it faces competition from rivals like AT&T and Verizon Wireless.
Verizon Wireless offered 4G in December 2010 and AT&T in early 2011.
