eSIMatrix does not offer an unlimited data eSIM for Brazil. The provider’s offerings for Brazil consist of fixed data plans: Brazil 20 GB - 5 days for $44.00 USD, Brazil 20 GB - 10 days for $49.00 USD, Brazil 20 GB - 15 days for $51.50 USD, and Brazil 20 GB - 30 days for $54.00 USD. There is also a South America 20 GB plan that covers Brazil and 16 other countries for $70.00 USD.
Choosing a fixed data plan may be more cost effective for most travelers, unless the user is an extremely heavy data consumer who would consider an unlimited option.
