In Short

Verizon Wireless is the largest wireless carrier in the United States, with over 145 million customers. Although we often refer to Verizon as a carrier, it is actually a large telecommunications company that offers wired internet, phone and television service and also operates its subsidiary, Verizon Wireless, as the wireless carrier.

Verizon Wireless' network consists of a CDMA 3G network and LTE 4G network, the latter of which has offered generally comprehensive nationwide coverage for a couple of years now. Verizon was the first carrier in the U.S. to launch an LTE device, the HTC Thunderbolt, along with a handful of markets at the end of 2010. Currently the carrier has no plans to shut down its CDMA 3G network until at least 2022, when it will start to sunset some markets, with no final operation date yet set.
