More Customers Losing Landlines and Going Solely Mobile

A third of 18-to-29-year-olds use only a mobile phone or the Internet for their calls.

With more than 200 million mobile users in the U.S. and in excess of 2 billion globally, mobile phones are an important communication force. A growing number of these consumers are eliminating their land-based phone line and relying on their mobile phone.

Over half of US adults who only use a mobile phone are younger than 30, according to a Harris Interactive study conducted between October and December 2006. In fact, a third of 18-to-29-year-olds use only a mobile phone or the Internet for their calls.

Over eight in 10 US adults said they had a landline phone, and over three-quarters said they had a mobile phone. About one in six used an internet phone based system (VoIP). Only 2% said they did not have phone service at all.

About six in 10 US adults used multiple approaches to making telephone calls. Just less than one in five used only a landline phone.
