Roaming charges in Brazil depend on the home operator, tariff and whether Brazil is included in a travel pass. Do not assume that a plan covering another part of the Americas automatically includes Brazil.
Unexpected charges usually come from background data, automatic network use or the home SIM remaining available for mobile data. Check the operator’s written terms before departure.
A NoveSIM Brazil plan is data-only. It can replace home-SIM data use, but it does not provide a Brazilian number, traditional calls or SMS.
Quick answer: Confirm Brazil roaming prices with the home carrier, disable data roaming and mobile-data switching on the primary SIM, and select a Brazil eSIM for data. Pause backups before landing.

Check the home tariff first
Record the daily pass price, data allowance, fair-use limit and what happens after the allowance. A vague “international†label is not proof that Brazil is included.
Prevent accidental home-SIM data
Select the eSIM for mobile data, turn off data roaming on the primary SIM and disable automatic data switching. Use the background-data controls.
Choose an alternative
Compare a travel eSIM, local SIM and Wi-Fi based on route and length of stay. The Brazil eSIM guide explains the data-first option.
Prepare travel beyond cities
Download complete road and onward routes because coverage can vary. Review mobile internet in Brazil rather than treating roaming price as the only decision.
