Hello and thank you for your question.

Standard & Poor’s Telecommunications: Wireless Industry Survey
provides a 50 page detailed report which I made use of in answering
your question.
 
Based on estimates from the Cellular Telecommunications &
Internet Association (CTIA), total U.S. wireless penetration reached
39% of the U.S. population (based on 109.5 million estimated total
customers).
