Best eSIM for São Paulo in 2026
— Ranked by Real Performance
São Paulo's eSIM connectivity relies heavily on Vivo and TIM's extensive urban networks, with Claro providing crucial backup coverage in the city's dense financial districts. The non-obvious reality is that many international eSIM providers route through Vivo's network infrastructure, which can create congestion during peak business hours in areas like Faria Lima and Vila Olímpia due to the concentration of multinational corporations.

- →Claro provides 98% coverage in the metropolitan region but struggles with indoor penetration in older buildings
