Unlimited Smartphone Data Plans in Older Adults With Data Deprivation: Quasi-Experimental Study.

Abstract

The growth of mobile health has underscored the critical importance of equitable internet access in promoting healthy aging. Among older adults, particularly those in digitally underserved populations, access to mobile data is often limited due to affordability and technological barriers, leading to a phenomenon known as "data deprivation." This form of digital inequality limits the older adults' ability to participate in social, recreational, and community-based activities, which are protective against isolation and decline in later life. In South Korea, where unlimited smartphone data plans have become increasingly accessible, a unique opportunity exists to examine the real-world association of improved data accessibility on older adults' social lives and digital engagement.
