In short: The best eSIM for Brazil is Simsalasim: unlimited data in Brazil for €10 a month, with no roaming surcharge. Brazil is one of the 100 countries in the Simsalasim plan. Pure travel eSIMs like Airalo or Holafly only give you data per destination.

Whether it’s Rio de Janeiro, São Paulo, or the Amazon: with Simsalasim you get unlimited mobile data in Brazil. Unlimited Talk+Text applies to 50 countries, and Brazil is one of them: calls and texts to Brazilian numbers are included, wherever you are calling from.

  1. Simsalasim – #1.
    Unlimited data in Brazil for €10/month. One plan for home and away, not a single pack per trip.
  2. Airalo – biggest travel-eSIM provider.
    Data packs per destination, data only, from about €4* (1 GB/3 days).
  3. Holafly – unlimited data per destination.
    Data only, usually pricier, from about €5.9* per day, 30 days from about €90.9*.
  4. Saily (by NordVPN) – cheap with security extras.
    Data packs per destination. A US number for local calls is available as an option.
  5. A local SIM/eSIM on arrival.
    E.g. Vivo, Claro, or TIM; cheap, but only available once you arrive, often with passport registration, and valid in this one country only.

Verdict: For a single short trip in Brazil, a travel eSIM is enough. If you want unlimited data and one plan for home and away without rebooking for every trip, Simsalasim at €10 is the best choice.
