How can I avoid roaming charges when visiting Brazil?

To avoid roaming charges when visiting Brazil, turn off data roaming on your home SIM and use a local solution instead. The most convenient option is a Brazil eSIM for tourists, which you can install before departure and activate on arrival to get local data at predictable prices. You can then use apps like WhatsApp, Telegram, and Skype for calls and messages over data instead of traditional voice and SMS. Public Wi‑Fi can help reduce data usage, but it’s often unreliable during busy periods like Carnival, so having your own eSIM data plan is the safest way to avoid surprise bills.
