Home Broadband 2015 | Pew Research Center: Still, the fact that more Americans have only a smartphone for online access at home has consequences for how people get information. Those who are “smartphone-dependent” for access do encounter distinct challenges. Previous Pew Research Center findings show that they are more likely than other users to run up against data-cap limits that often accompany smartphone service plans. They also more frequently have to cancel or suspend service due to financial constraints.This study paints a grim picture of the state of telecommunications in the United States. On the sell side, market failure leaves many premises without landline Internet service. Service providers redline and refuse to serve neighborhoods where the business case can't be justified. On the buy side, in neighborhoods they do offer landline service, it's perceived as unaffordable. That forces many to rely on mobile wireless service via smartphones that has its own affordability issues and suffers from serious user limitations.
