Brazil is Latin America's largest mobile market with around 250 million subscriptions, dominated by four operators: Vivo (Spain's Telefónica, market leader), Claro (Mexico's América Móvil), TIM Brasil (Telecom Italia), and Oi (whose mobile business was acquired by the top three in 2022). Prepaid plans dominate, and USSD is used for balance enquiries, data pack subscriptions, and number lookup.
