Internet in Brazil for Tourists: Roaming vs eSIM

Getting internet in Brazil as a tourist comes down to three options: roaming on your home plan, relying on Wi-Fi, or using a travel eSIM. Each works, but they're not equal once you're out of the hotel and need a ride, a map or a reply on WhatsApp.

Here's how they compare, and which apps you'll actually need once you land.

Roaming vs eSIM vs Wi-Fi: what works in Brazil

Home-carrier roaming is the easy default, but it's usually expensive. Many carriers sell day passes that add up quickly over a one- or two-week trip.

Wi-Fi is common in hotels, cafés and malls, but it's patchy everywhere else: on the beach, in an Uber, on a trail or while you're searching for a restaurant. You'll also be asked for your connection the moment you land, to call a ride or message your host.

A local prepaid SIM from TIM, Claro or Vivo requires a CPF or registration with your passport, a store or kiosk, and often a queue. If you want the details, see our guide to the Brazil SIM card for tourists.

A travel eSIM gives you local data from the moment you land, without swapping SIM cards or visiting a shop.

Why a travel eSIM is the simplest option

VoaSim is a Brazilian company, so it knows the local networks and the country. Its Brazil eSIM includes unlimited data on 4G/5G networks in the state capitals and along the tourist coast.

• Installs in about 2 minutes by QR code, before your trip or on the airport or hotel Wi-Fi.
• Data-only: no Brazilian number, but your home SIM stays in the phone, so your number and WhatsApp keep working.
• No CPF, no store, no queue. Pay by card in USD through Stripe, with a receipt.
• 24/7 human support by WhatsApp and e-mail in English, Spanish and Portuguese.
• Full refund if the eSIM doesn't connect and support can't solve it.

Plans start at USD 6.90 for 1 day; 15 days is USD 49.90. Ordering 2 or more eSIMs together gives 10% extra off. See all Brazil eSIM plans. Your phone must be carrier-unlocked and eSIM-compatible, such as iPhone XR or newer, Samsung Galaxy S20 or newer, or Google Pixel 3 or newer.

WhatsApp runs everything in Brazil

In Brazil, WhatsApp isn't just a chat app. Restaurants take reservations on it, tour operators send meeting points, Airbnb hosts share check-in instructions, and many shops and businesses answer customers there instead of by phone or e-mail.

That's why being reachable on WhatsApp matters more than having a local phone number. With a data-only eSIM, your existing WhatsApp account keeps working on your usual number, so contacts at home and new contacts in Brazil can both reach you.

Payments, rides, maps and food apps

• Pix is Brazil's instant payment system and you'll see Pix QR codes everywhere, from street vendors to stores. Cards are widely accepted in cities too, so you won't be stuck without it.
• Uber and 99 are the main ride-hailing apps. They're the easy way to get from the airport, between neighborhoods or home after dinner.
• Google Maps and Waze handle navigation, walking routes and public transport info.
• iFood is the go-to food delivery app if you want dinner at your hotel or rental.

All of these need mobile data on the go, which is where Wi-Fi alone falls short. Heading somewhere specific? Check our tips for Rio de Janeiro and Florianópolis.

Turn off data roaming on your home line

Once your eSIM is installed and active, go to your phone's cellular or mobile data settings and set the eSIM as the line for mobile data. Then turn off data roaming on your home line.

This keeps your home SIM available for calls and texts if you need them, while making sure all internet traffic goes through the eSIM instead of triggering roaming charges from your carrier. On the eSIM line itself, data roaming may need to stay on; follow the installation instructions you receive.
