eSIM4Travel does not provide a truly unlimited data eSIM for Brazil. All plans that carry the word “Unlimited” in their name, such as Unlimited‑3Days‑Brazil (Vivo) and Unlimited‑5Days‑Brazil (Claro), have a data cap of 3GB per day and a validity of 3 to 10 days. The provider notes confirm that the name does not indicate unlimited data.
Travelers who need larger data allowances can choose fixed data plans that offer unthrottled high‑speed data for 30 days, such as the 20GB/30Days plan for Brazil on the Vivo network or the 20GB/30Days plan on the Claro network. These fixed data plans can be more cost‑effective for heavy data users.
