Verizon is the #1 wireless phone service in the US (ahead of rival AT&T Mobility) and the #2 US telecom services provider overall (after AT&T). The company's core mobile business, Verizon Wireless, serves about 113 million retail connections. Verizon's wireline unit, with more than 18 million voice connections (end of 2015), provides local telephone, long-distance, internet access, and digital TV services to residential and wholesale customers.
