Brazil has four main operators: TIM, Claro, Vivo, and Oi. HelloRoam eSIMs connect via TIM, which operates the widest 5G rollout in the country. TIM launched 5G in Sao Paulo, Rio de Janeiro, Brasilia, Belo Horizonte, and Salvador, with ongoing expansion to secondary cities.
In Sao Paulo, average 4G speeds range from 25 to 60 Mbps in the city center. The metro system has 4G coverage at most stations. In Rio de Janeiro, the Zona Sul beach neighborhoods (Ipanema, Copacabana, Leblon) have strong 4G. Favela areas and hillside communities can have weaker signal due to terrain.
The northeast coast cities including Fortaleza, Natal, Maceio, and Porto Seguro have reliable 4G along beach areas and in town centers. The Iguazu Falls area on the Brazilian side has solid 4G service. Ferry crossings between Salvador and the island of Itaparica can see brief signal drops mid-crossing.
