Motorola reported that 46% of its cell phone sales in 2007 were in the United States, up from 35% of sales in 2006. The proportion of its total sales, not just handsets, to the U.S. market also increased to 51% in 2007, up from 44% in 2006.

The struggling handset manufacturer announced that its top handset client in 2007 was the also struggling carrier Sprint Nextel, and that its top five handset clients represented 42% of its sales. Top clients behind Sprint were AT&T, Verizon Wireless, China Mobile and America Movil. Though Motorola said that no single customer represented more than 10% of its sales in 2007.

Outside the United States, the handset manufacturer said its biggest markets in 2007 were Brazil, China and Mexico.
