Sprint

Sprint Corporation, commonly referred to as Sprint, is an American telecommunications company that provides wireless services and is an internet service provider. It is one of the largest mobile network operator in the United States, and serves 54 million customers as of October 2017. 
The company also offers wireless voice, messaging, and broadband services through its various subsidiaries under the Boost Mobile, Virgin Mobile, and Assurance Wireless brands, and wholesale access to its wireless networks to mobile virtual network operators. The company is headquartered in Overland Park, Kansas.
Sprint traces its origins to the Brown Telephone Company, which was founded in 1899 to deploy telephone service to the rural area around Abilene, Kansas. In 2006, Sprint exited the local landline telephone business, spinning those assets off into a newly created company named Embarq, which later became a part of CenturyLink. The company continues to be one of the largest long distance providers in the United States.
Prior to 2005, the company was also known as the Sprint Corporation, but took the name Sprint Nextel Corporation when it merged with Nextel Communications that year. In 2013, following the shutdown of the Nextel network and concurrent with the acquisition by SoftBank, the company returned to using simply Sprint Corporation.
