Claro in Brazil

Claro is one of Brazil’s three national carriers, and the network the eSIM Americas Brazil eSIM uses.

Claro’s place in the market

Brazil’s telecoms regulator, ANATEL, counted 276.4 million mobile accesses in the second quarter of 2026, 3.7% more than a year earlier. Its competition report places Claro second with 33.2% of the market, between Vivo’s 37.9% and TIM’s 22.4%, and records 916 thousand new Claro accesses in the quarter. Lines on 5G reached 23.9% of the total, or 66.1 million.

Where Claro has 5G

Brasília was the first city in Brazil where 5G went live, on 6 July 2022, and Claro was one of the three carriers that switched it on there. Three years later the country counted 1,025 municipalities with 5G and 47.2 million customers, more than 70% of the population. 5G needs a phone that supports it, and a plan card here names 5G only where the store confirms it for the plan.

Check the signal before you go

ANATEL requires every operator to publish a coverage map for each technology it sells. The regulator points out that the maps are built from prediction models, so the signal indoors is not guaranteed. Claro’s own map, drawn from ANATEL’s data, covers almost 4,800 cities and shows its 5G, 4G, 3G and 2G layers by place.
