More than two-thirds of U.S. mobile phone subscribers prefer data plans that cover only smartphones, while the rest prefer plans that would extend to multiple devices, such as tablets and laptops, Parks Associates found in a study released early Wednesday (http://bit.ly/Ubnio3) in anticipation of Amazon’s announcement of a smartphone and subsidized mobile data plan. Two in every three subscribers would rather buy a smartphone at full price in return for scrapping a contract. Lower-income subscribers especially like the idea of unsubsidized handsets because they believe it will lower their monthly fees, the study found.
