Brazil eSIM for tourists: get connected before you land

Your first hour in Brazil is easier when you can find your hotel, message your host and arrange your next stop. Set up your connection before the flight, and you can spend that hour getting somewhere you want to be.

Need mobile data? Choose a prepaid eSIM for your unlocked phone. Need a Brazilian number? Choose a plan with local calls and SMS. TIM and Claro also document passport registration routes without CPF, Brazil's taxpayer number.

Choose your connection for Brazil

• Maps and messages: a data eSIM. Compare fixed-data plans against your recent usage. The 3–5 GB examples below are a useful starting point if you mainly use maps and WhatsApp. Compare data plans.
• Calls and Brazilian SMS: a local number. Choose local voice and SMS. Follow TIM or Claro's documented passport route, or confirm Vivo's tourist registration before buying. See passport routes.
• Laptop and video calls: more data to share. Compare the total allowance, hotspot limit and reduced speed. Unlimited data can still have a daily tethering limit. Check hotspot limits.

No eSIM support? Use a physical SIM in an unlocked phone. Visiting Argentina too? Check that your package includes both countries.

Check your existing mobile plan too. If it already includes enough Brazil roaming, you may not need another SIM. Confirm the allowance, speed and charges with your carrier before leaving.

An eSIM is the digital version of a SIM card. It does not tell you whether the service includes a phone number, SMS or only internet access. Read the package details, not just the word eSIM.

Get online, then get ready to pay locally. Add US$50 to Tucu and get a free Brazil eSIM: 3 GB of data for 30 days, starting when you land. Then pay supported Pix QR codes without a Brazilian bank account, and see the full dollar cost before confirming. Join the waiting list for early access.

Brazil eSIM prices and local options

Here are representative packages advertised by the providers, checked on 12 October 2026, and Guac's on 13 October 2026. International-provider prices are in US dollars, and Vivo's price is in Brazilian reais. Compare the allowance and duration together. These are examples, not a ranking of network performance.

Check the current package, final checkout total and refund conditions before paying. Coupons, credit-card conversion fees and changed tariffs can alter the comparison.

Need a Brazilian number? Look at the local option before buying a data-only plan. Vivo advertises local calls and SMS, credit-card payment and hotspot use. Confirm the tourist registration and device requirements first. Its purchase page returned an error when checked for this guide, so arrange a working arrival connection before relying on that offer. Vivo's tourist-plan details.

Check your phone before paying for an eSIM

You need two things: an eSIM-compatible phone and permission to use another carrier. A recent phone can still be locked to the carrier that sold it.

On iPhone, open Settings → General → About and check Carrier Lock. An unlocked phone shows No SIM Restrictions. Compatibility also depends on the model and where it was sold, so check Apple's regional guidance rather than assuming every recent iPhone works. Apple's travel eSIM guide.

On Android, check the exact model and market variant. Pixel and Samsung have their own installation menus and compatibility conditions. Look for Add eSIM in the SIM settings, then confirm support with the manufacturer and provider. The menu alone does not prove that the phone is unlocked. Google Pixel guidance, Samsung guidance.

If your phone cannot use an eSIM, a physical SIM may suit you. Check that it has a SIM tray and is unlocked before planning a store visit.

Can tourists buy a Brazilian SIM without CPF?

Yes, documented passport routes exist. The important part is using the carrier's process for foreign visitors.

TIM says visitors can obtain a SIM at its own or partner stores and register for an available prepaid offer. Its required details include a passport, RNE or eligible foreign identity document, the address where you are staying, the issuing country and other personal information. TIM's foreign-visitor FAQ.

Claro directs foreigners without CPF to physical Claro stores, with a passport or RNE. Buying a card from a kiosk or supermarket is not the same as completing that registration process. Claro's instructions.

Bring your passport and accommodation address. Ask for the foreign-visitor prepaid route, check the total package price and test the connection before leaving. Use your own identity details. If the ordinary online form insists on CPF, follow the carrier's documented alternative.

Will a data eSIM work with WhatsApp and verification codes?

You can keep using an existing WhatsApp account with its registered home number while another SIM supplies the internet connection. If you need to verify the account again, you still need access to the registered number through an available verification method. WhatsApp's roaming guidance, SIM and account guidance.

A data-only package does not give you a Brazilian SMS number. Saily's optional phone-number service is US-based, and its support guidance says some services reject numbers identified as VoIP. Do not buy it assuming it will satisfy a Brazilian app's local-number requirement. Saily's number service, verification limits.

If a service you need asks for a Brazilian number or CPF, resolve that account requirement separately. Our iFood guide and CPF guide for tourists explain why an internet connection alone does not complete registration.

How much data do you need for Brazil?

Use your own recent mobile-data usage as the starting point. Look at a known period in your phone's settings, divide the usage by its days, then multiply by your trip length. Adjust for the way you will travel: reliable accommodation Wi-Fi, photo uploads, video calls and laptop tethering all change the budget.

For a simple planning example, a 3 GB total allowance spread over seven days is about 430 MB a day. Across 14 days it is about 215 MB a day, and across 30 days about 100 MB. These are approximate budgeting figures, not daily allowances or a promise that 3 GB will last your trip.

Make the data you buy go further:

• Download maps and media on Wi-Fi before leaving.
• Restrict photo backup, app updates and automatic media downloads on mobile data.
• Use your phone's data-saving settings and check which apps consume the most.
• Count your laptop's traffic if you share the connection.
• Check your remaining allowance while you still have a connection to buy more.

Apple provides app-level usage controls and Low Data Mode for reducing background activity. Downloaded Google Maps areas help too, but offline mode does not provide walking, cycling or public-transport directions, or live traffic. Keep a saved hotel address as well. Apple data settings, Google Maps offline limits.

What does unlimited data mean?

Check the high-speed allowance, the reduced speed and the hotspot limit. Unlimited total data does not necessarily mean unlimited full-speed laptop use.

Airalo's general unlimited policy has a default 3 GB high-speed allowance per 24 hours, then 1 Mbps, unless the package specifies a different threshold. Shared hotspot traffic counts toward that allowance. Saily's Brazil unlimited selection also advertises 3 GB per day at unrestricted speed, followed by up to 1 Mbps. Airalo's fair-use policy, Saily's Brazil plans.

Holafly's Brazil package allows 1 GB of hotspot sharing per day and says local-network fair use may temporarily reduce speed. If you need to work from a laptop, compare those terms with a larger fixed-data package before choosing. Holafly's Brazil package.

Install before flying, activate according to your plan

Installing puts the eSIM on your phone. Activation starts the service according to the package's rules. They can happen at different times.

Before your flight:

1. Check your phone and choose a package that covers your trip.
2. Read its installation instructions and activation deadline.
3. Install using a reliable Wi-Fi or mobile connection. Give the new line a recognisable name, such as Brazil or Travel.
4. Save the provider's support route and your essential arrival details.
5. Check the home carrier's charges if you intend to keep its number active.

Avoid using one provider's activation instructions for another:

Vivo timing, Ubigi activation, Saily Brazil, Saily data-management guidance.

When you land: turn on the travel line and select it for mobile data. Enable roaming on that line if the provider instructs you to. Saily, for example, requires it. Keep automatic mobile-data switching off when the provider advises it, so the phone does not silently use your home line for data. Saily setup guidance.

If you keep the home SIM active for verification codes, turn off its data roaming and check its tariff. Calls, SMS, voicemail or a daily roaming pass can still carry charges. Turning off data roaming does not make every use of the home line free. Apple's dual-line travel guidance.

Test a normal web page with Wi-Fi off while you still have a way to contact support. That small check is more useful than discovering the wrong data line is selected after leaving the airport.

Check coverage for the places you will visit

Choose a plan with suitable networks for your route. The current Airalo Brazil page lists TIM, Ubigi lists TIM Brasil and Vivo, and Holafly lists Claro, TIM and Vivo. Saily's technical text describes partner networks without naming them. Check the exact package because network access can change.

Use the permitted carrier's coverage map for your accommodation and onward journey. Anatel explains that these maps predict signal: terrain, buildings and indoor location affect the connection you receive. A country in the coverage list is not a guarantee of signal everywhere within it. Anatel's explanation and carrier maps.

For rural roads, parks or remote stays, ask the accommodation which carrier works locally and save essential information offline. Having mobile data also does not make online wallet payments possible where there is no working connection. Carry a suitable backup payment method for your trip.

If your Brazil eSIM has no internet

Start with the settings that determine which line is supplying data:

1. Check the package. Are you in a covered country, with time and data remaining?
2. Check the line. Is the travel eSIM enabled and selected for mobile data?
3. Check roaming. Use the provider's instruction for that line, keeping the home line's charges in mind.
4. Follow its network settings. An APN is the connection setting some plans require. Use the provider's exact value rather than copying one from an unrelated guide.
5. Follow its reconnect instructions. These may include switching airplane mode on and off or choosing a permitted network manually.
6. Use Wi-Fi to contact support if the connection still fails.

Keep the eSIM installed while troubleshooting. Deleting it may require a replacement, and reinstall rules vary. Vivo's linked support guide, for example, says a deleted profile needs a new QR code from a store. Vivo's installation and troubleshooting guide.

Missing SMS is a different problem. A working data connection cannot receive a text for a phone number the package does not include.

Report a connection fault while the provider can investigate it. Refunds depend on the provider, whether the service was activated or used, and the reason for the request. Read the relevant policy before activating: Airalo, Saily, Ubigi, Holafly.

Get connected, then get ready to pay with Tucu

Once your phone is online, prepare for the other part of everyday life in Brazil: paying locally. A merchant's Pix QR code still needs a payment method that can pay that code. Our Pix guide for tourists explains your options.

Tucu is designed to let travellers pay supported Pix QR codes without opening a Brazilian bank account. Add money to your travel balance, scan the merchant's code and see the full cost in dollars before confirming. You can choose your lunch, your coffee or your next stop with a local payment option already prepared.

Tucu also gets you online: add US$50 to your balance and you get a free Brazil eSIM with 3 GB of data for 30 days. It comes from Guac, our eSIM company. Install it before you fly, and its days start when you land. When the data runs low, top it up from your Tucu balance.

Join the waiting list for early access and select Brazil so we can contact you about access for your destination.

For a fuller arrival plan, read how to pay in Brazil. If you want to compare payment costs, use the Pix versus card calculator with your own rates and fees.

Frequently asked questions

What is the best eSIM for Brazil?

Choose one that works with your unlocked phone, covers your route and includes enough data for your trip. If you need a Brazilian number, choose a plan with local voice and SMS. For laptop use, check hotspot and reduced-speed limits. The right choice depends on those needs, not only the lowest starting price.

Do I need a CPF to buy a SIM card in Brazil?

Not for every registration route. TIM documents passport registration for foreign visitors, and Claro directs foreigners without CPF to physical stores with a passport or RNE. Follow the carrier's visitor process. An ordinary checkout that asks for CPF does not establish the requirements of every Brazilian SIM.

Can I keep my WhatsApp number with a Brazil eSIM?

Yes. An existing WhatsApp account can keep its registered number while using another SIM's data. You still need access to that number through an available verification method if the account requires verification again. A data-only eSIM does not provide SMS service for your home number.

Should I install my Brazil eSIM before travelling?

Install over a working internet connection before departure if the provider permits it, and follow the package's activation rules. Installation and service activation are different. Vivo's tourist plan has a 15-day purchase-to-activation deadline and recommends activation after arrival. Other providers have different rules.

Will a Brazil eSIM also work in Argentina?

Only if that package includes Argentina. A Brazil-only label does not establish cross-border service. Check the countries and activation rules of a regional plan, or arrange separate plans. Tucu's free eSIM covers the one country you pick, Brazil or Argentina.

Can I share my eSIM data with a laptop?

Check the exact plan's tethering terms. The sampled Ubigi fixed-data plan allows sharing, while Holafly's Brazil plan limits hotspot sharing to 1 GB per day. Shared usage consumes the relevant allowance, and unlimited plans may reduce speed after a high-speed limit.

Can I keep my home SIM active for bank codes?

On a phone that supports both lines, you can use the travel eSIM for data while keeping your home line active for texts. Check your home carrier's international SMS and roaming terms first. Turn off home-line data roaming, and remember that calls, voicemail or a daily roaming pass may still carry charges.
