Brazil is one of the most breathtaking destinations on the planet — from the white-sand beaches of Florianopolis to the thundering falls of Iguacu and the electric streets of Rio de Janeiro. But there is one thing almost every visitor discovers on arrival: staying connected to the internet is harder than you expected.
Whether you need Google Maps to navigate Sao Paulo's labyrinthine streets, Uber to get around safely at night, WhatsApp to communicate with local hosts (Brazilians live on WhatsApp), or just a reliable connection to share your trip with friends back home, internet access is not a luxury — it is a necessity.
This guide compares every option available to foreign tourists in Brazil in 2026. We break down the real costs, the hidden catches, and the practical pros and cons so you can pick the best solution before you board your flight.
1. International Roaming: The Expensive Default
How It Works
International roaming is the simplest option on paper. You land in Brazil, your phone connects to a local network, and your home carrier charges you for every megabyte of data, minute of calls, and text message you send.
The Real Cost
Most major carriers from the US, UK, and Europe charge between $5 and $15 per megabyte of roaming data in Brazil. Yes, per megabyte — not gigabyte. A single Instagram scroll could cost you $20. Streaming a short YouTube video could run $50 or more.
Some carriers offer international day-passes ($10-$12/day), but these come with low data caps and still add up to $70-$84 for a one-week trip — far more than other options.
Hidden Fees and Bill Shock
The biggest danger with roaming is "bill shock." Background apps, automatic photo uploads, and software updates can consume data without you realizing it. Travelers have reported returning home to bills of $200, $500, or even over $1,000 from a single week in Brazil.
When Roaming Makes Sense
International roaming only makes sense for very short trips (under 24 hours) or as an absolute emergency backup when no other option is available.
Verdict
Expensive, unpredictable, and risky. Avoid roaming as your primary internet source in Brazil.
2. Free WiFi in Brazil: Unreliable and Risky
Airport WiFi
Major airports like Guarulhos (GRU) in Sao Paulo and Galeao (GIG) in Rio de Janeiro offer free WiFi. However, it typically requires registration with a Brazilian phone number or CPF, the connection is slow, and it drops frequently. It is fine for sending a quick message while waiting for luggage — and nothing more.
Hotel and Hostel WiFi
Most hotels and hostels in Brazil include WiFi. Quality ranges from excellent in upscale hotels to barely functional in budget accommodations. Even good hotel WiFi keeps you tethered to the property — useless when you are out exploring all day.
Restaurant and Cafe WiFi
Chain restaurants (like Starbucks) and modern cafes in major cities usually offer WiFi. However, speeds are inconsistent, you often need to ask staff for a password, and the connection is rarely strong enough for video calls or heavy use.
Public WiFi Networks
Some Brazilian cities have public WiFi initiatives. Sao Paulo's WiFi Livre SP program provides free internet in parks and public spaces. While this is a great initiative, the coverage is limited, speeds are slow, and — critically — public WiFi is a security risk. Without a VPN, your personal data, passwords, and financial information are vulnerable on open networks.
Verdict
Free WiFi in Brazil is a useful supplement but completely unreliable as your only connection. The security risks of public WiFi make it unsuitable for banking, shopping, or entering sensitive information.
3. Local SIM Cards: Cheap but Complicated
Brazil's Major Carriers
Brazil has three main mobile carriers:
- Vivo — The largest carrier with the best nationwide coverage, including rural and remote areas. Uses Telefonica's infrastructure.
- Claro — Excellent coverage in urban areas and major cities. Strong 4G/5G network.
- TIM — The most budget-friendly option with competitive prepaid plans, though coverage is weaker in remote regions.
Where to Buy
You can purchase a local SIM at airport kiosks, official carrier stores in shopping malls, authorized resellers, and some newsstands (bancas de jornal). Airport shops are the most convenient but also the most expensive.
The CPF Problem
Here is the biggest obstacle most tourists do not know about: Brazilian carriers require a CPF (Cadastro de Pessoa Fisica) to activate a SIM card. A CPF is the Brazilian tax identification number — similar to a Social Security Number in the US.
As a foreigner, you do not have a CPF. While some airport shops and resellers sell pre-activated SIM cards that bypass this requirement, this is technically a gray area. These workarounds are unreliable — sometimes they work, sometimes they do not, and the SIM could be deactivated later.
Cost
Prepaid plans typically cost between R$30 and R$80 (roughly $6 to $16 USD) for 7 to 30 days of data. This makes local SIMs one of the cheapest options on paper.
Pros
- Affordable plans
- Local Brazilian phone number (useful for some services)
- Good data allowances
Cons
- CPF requirement creates a real barrier for tourists
- Requires visiting a physical store
- Language barrier (most staff speak limited English)
- Takes 30-60 minutes to purchase and set up
- You must swap or remove your home SIM card
Verdict
Local SIM cards offer great value but the CPF requirement, store visit, and language barrier make them complicated and time-consuming for foreign tourists.
4. Portable WiFi (Pocket WiFi): Decent for Groups
How It Works
A portable WiFi device (also called a pocket WiFi or MiFi) is a small battery-powered router that connects to the local cellular network and creates a personal WiFi hotspot. You connect your phone, tablet, or laptop to the hotspot just like any WiFi network.
Where to Rent in Brazil
Several companies rent pocket WiFi devices in Brazil, typically through online booking with airport pickup and return. Some hotels also offer rental services.
Cost
Expect to pay $8 to $15 per day, which adds up to $56-$105 for a one-week trip — more expensive than a local SIM or eSIM, but the device can connect 5-10 devices simultaneously.
Pros
- Connects multiple devices at once (great for couples or groups)
- No SIM card needed
- Easy to use
Cons
- Battery life lasts only 6-8 hours (you are carrying a charger too)
- Must carry an extra device everywhere
- Must return the device before departure (risk of fees if damaged or lost)
- Deposit often required
Verdict
Pocket WiFi is a decent option for groups or families traveling together. For solo travelers or couples, an eSIM is simpler and more cost-effective.
5. eSIM: The Best Option for Most Tourists
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM built directly into your smartphone. Instead of inserting a physical card, you download a cellular plan by scanning a QR code. Your phone connects to a local network — no store visit, no paperwork, no waiting.
Think of it like this: a traditional SIM is like a DVD. An eSIM is like Netflix. Same result, far more convenient.
How It Works
- Purchase your plan online — Choose your data plan and trip duration before you leave home.
- Receive a QR code — Delivered instantly to your email.
- Scan and install — Add the eSIM profile to your phone in under 2 minutes.
- Activate on arrival — Turn on the eSIM when your plane lands in Brazil. You are connected before you leave the airport.
Compatible Devices
Most smartphones released since 2018 support eSIM:
- Apple: iPhone XS, XR, and all newer models (including iPhone 15 and 16 series)
- Samsung: Galaxy S20 and newer, Galaxy Z Fold/Flip series
- Google: Pixel 3 and newer
- Other: Motorola Razr, Huawei P40+, and more
Tip: Check your phone settings for "Add eSIM" or "Add Cellular Plan" to confirm compatibility.

- Works on landing — Turn it on as the plane touches down. Uber from the airport, navigate to your hotel, message your host — all within minutes of arrival.

Practical Tips for Staying Connected in Brazil
- Download offline maps — Google Maps and Maps.me allow you to download areas for offline navigation. Do this before your trip as a backup.
- Get WhatsApp — If you do not already have it, install WhatsApp before arriving. It is the primary communication tool in Brazil. Restaurants, tour guides, hotels, and even businesses use it instead of email or phone calls.
- Use a VPN on public WiFi — If you must connect to free WiFi, always use a VPN to protect your data.
- Set up your eSIM before departure — Install the profile at home. Activate it when you land. This way you are connected the second you step off the plane.
- Disable data roaming on your primary SIM — Avoid surprise charges by turning off roaming on your home carrier line.
- Carry a portable charger — Whether you use an eSIM, local SIM, or pocket WiFi, heavy data use drains your battery. A 10,000mAh power bank is a travel essential in Brazil.
FAQ: Internet in Brazil for Tourists
Can I use my phone normally in Brazil?
Yes. As long as your phone is unlocked and you have an internet connection (via eSIM, local SIM, or WiFi), all your apps work normally in Brazil. WhatsApp, Google Maps, Uber, Instagram, and banking apps all function as expected.
Do I need a CPF to get internet in Brazil?
Only if you buy a local SIM card from a Brazilian carrier. Carriers like Vivo, Claro, and TIM require a CPF (Brazilian tax ID) for SIM activation. With an eSIM like FlyConnecta, no CPF is needed.
Is free WiFi safe in Brazil?
Free WiFi in Brazil carries the same security risks as anywhere else — your data can be intercepted on open networks. Avoid accessing banking apps or entering passwords on public WiFi unless you are using a VPN.
How much data do I need for a trip to Brazil?
For typical tourist use (maps, messaging, social media, ride-hailing, and light browsing), most travelers use 1-3 GB per day. If you plan to stream video or make frequent video calls, you will use more. FlyConnecta offers plans designed to cover all standard travel usage.
Can I use WhatsApp in Brazil with an eSIM?
Absolutely. Your WhatsApp remains linked to your home phone number. The eSIM simply provides the data connection. You can send messages, make voice and video calls, and share media through WhatsApp with no issues.
Will my eSIM work outside major cities?
FlyConnecta eSIMs use Brazil's major carrier networks (Vivo, Claro, TIM), which cover all major cities and most tourist destinations. In very remote areas (deep Amazon, isolated rural zones), coverage may be limited — but this is true for all cellular options, not just eSIM.
Can I use an eSIM and my regular SIM at the same time?
Yes. Most modern smartphones support dual SIM — one physical SIM and one eSIM active simultaneously. This means you can keep your home number active for incoming calls while using the eSIM for data in Brazil.
What if my phone does not support eSIM?
If your phone does not support eSIM, a local SIM card or pocket WiFi rental are your best alternatives. Check your phone's settings or contact your manufacturer to confirm eSIM compatibility before your trip.
Stay Connected from the Moment You Land
Planning a trip to Brazil should be exciting, not stressful. Connectivity is one of those problems you can solve completely before you even pack your bags.
With FlyConnecta, you purchase your Brazil eSIM online, receive your QR code instantly, and activate it the moment your plane touches down. No CPF paperwork. No store visits. No language barriers. No extra devices to carry. Just reliable, fast internet across Brazil from the second you arrive.
