How much will it cost for your trip?
Brazil has 4 mobile networks: Vivo (Telefônica — ~38% market share, the only carrier with 100% of Brazilian municipalities covered by 4G; widest 5G geographic reach), Claro (~33% market share, fastest 5G speed in dense urban areas — Ookla 5G speed leader 2025), TIM (~23%, competitive pricing, solid 4G in cities), and Oi (in restructuring, less consistent). For São Paulo, Rio, Brasília, Salvador, Recife, all four work in city centres. Coverage drops significantly off the coast: Amazon interior (deep jungle past Manaus), Pantanal, Chapada Diamantina rely on Vivo's 700 MHz spectrum and have weak-or-no signal on competitors. For Amazon expeditions, no mobile network is reliable past major river towns — consider a satellite communicator. Verify which underlying network your travel eSIM routes through; Claro or Vivo are the safest defaults. Download offline maps for all routes before leaving São Paulo, Rio, Salvador or Manaus.
Brazilian local SIM cards (Vivo, Claro, TIM, Oi) require CPF (Brazilian tax ID) or passport for activation. Some operators charge a registration fee of R$10–20 (~$2–4) for the SIM and registration process. Tourist plans range from TIM's "Tim Visitor" R$25 (~$4) for 1.5 GB / 7 days, to Claro's R$100 (~$17) for 4 GB. International travel eSIMs are exempt from this registration — they roam onto Brazilian networks via international agreements and operate without local paperwork. Practical note: Brazil's Federal Supreme Court has occasionally suspended specific apps (WhatsApp 2016, Telegram 2022, X/Twitter 2024) for short periods following court orders. These are exceptional, time-limited events rather than persistent restrictions, but worth being aware of for high-profile messaging dependencies — keep an alternative communication channel (email, alternative messaging) for any week-long trip.

eSIM — Brazil
Network coverage in Brazil
Brazil has three mobile operators: Vivo, Claro and TIM. For São Paulo, Rio de Janeiro, Brasília, Salvador and main coastal cities, all three perform well on 4G/5G. Vivo has the widest national footprint — the only operator covering every Brazilian municipality with 4G — which matters for itineraries beyond the coast. Vivo also leads on 5G download speeds, with Claro close behind; TIM leads on reliability and 5G availability.
Coverage drops significantly in the Amazon interior, the Pantanal and remote northern states — no carrier is reliable past major river towns. For these itineraries, see the field tip above for which network to prioritise and offline map advice before leaving the last connected city.

VPN, passwords and documents
Brazil has no general internet restrictions — all major platforms work normally. On public Wi-Fi (airports, hotels, cafés), a VPN masks your traffic from the network operator. A password manager and a secure cloud backup of your passport, insurance certificate and hotel bookings can also be useful — keep an offline copy too. None of these are mandatory.
