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

Although the overall association of unlimited data plans was limited, certain vulnerable subgroups-particularly older men living alone-experienced meaningful gains. These findings suggest that improving mobile data accessibility may enhance social engagement among digitally underserved older adults. Compared with more complex or resource-intensive interventions, expanding access to unlimited smartphone data plans may offer a relatively simple and scalable strategy to support healthy aging and reduce social isolation.
