SIM card for Brazil: What tourists can actually buy in 2026

Can tourists buy a SIM card in Brazil?

Tourists can buy a prepaid SIM card in Brazil, although buying a SIM card involves an extra activation process. Brazilian carriers normally register prepaid lines using a CPF, the country’s taxpayer identification or tax number. This forms part of Brazil’s mobile registration requirements rather than an individual store policy.

Foreign visitors without a CPF can still register prepaid service with some carriers by presenting a passport. For example, TIM states that visitors can register using a passport, RNE (foreign residency card), or eligible foreign identity document, while Claro allows foreigners without a CPF to activate a prepaid SIM at a physical store using a passport or RNE.

Vivo’s public prepaid guidance focuses on CPF registration and doesn’t explain the passport process as clearly. Travelers who want a Vivo SIM card should therefore visit an official Vivo store with their passport and confirm the requirements before buying.

You may also find prepaid SIMs at supermarkets, pharmacies, and newsstands, but simply buying the SIM card doesn’t complete registration. Avoid SIMs already registered in somebody else’s name and use an official carrier store if you need help activating a local SIM.

A travel eSIM like Saily eliminates that registration step. You can install it without a Brazilian CPF or an in-store passport check, so your mobile data can be ready before you arrive.

Can I use my US phone in Brazil?

Most recent US smartphones will work in Brazil, provided they are carrier unlocked and support the frequencies of Brazilian networks. If you bought yours through a US carrier, check how to tell if your phone is carrier unlocked before relying on a Brazilian SIM card or international eSIM.

Brazilian networks use several frequency bands for 4G and 5G, including 700 MHz, 1800 MHz, 2500 MHz, and 3.5 GHz. Recent iPhones, Google Pixel phones, and Samsung Galaxy models usually support the main frequencies, although older US carrier-specific devices may have more limited compatibility.

You can also use your US carrier’s international service, but international roaming charges and other roaming fees may make it an expensive option for a longer trip.

💡 Pro tip: Brazil uses type N power outlets, and voltage varies between 110/127V and 220V depending on the region. Bring an adapter and check the voltage before connecting equipment that doesn’t support both.

Which SIM card is the best for Brazil?

Vivo, Claro, and TIM are Brazil’s three main mobile networks. Their prepaid SIM prices are similar enough that coverage, itinerary, and usable data matter more than a small difference in cost.

Current packages from all three carriers cost around R$30 (about US$6) for roughly a month of service.

Opensignal’s January 2026 report found that Vivo had the fastest average overall and 5G download speeds nationally, while TIM performed particularly well for reliability. Regional results varied, so national rankings don’t tell you which network will work best everywhere.

All three carriers serve the Rio-São Paulo corridor and major coastal cities well. Coverage can become less predictable in the Amazon, Pantanal, and inland parts of the Northeast, so download offline maps before remote or long-distance travel, whichever provider you choose.

Vivo: The best coverage across Brazil

Vivo is one of Brazil’s largest mobile operators and performs strongly across many parts of the country. Opensignal’s January 2026 report found that Vivo delivered the fastest average download and 5G download speeds nationally.

The current Vivo Pré package costs R$30 (around US$5.90) and provides up to 25 GB for 30 days — 15 GB for general use, 5 GB of bonus data, and 5 GB for YouTube. You can manage the plan through the Vivo app and top up through carrier stores and other retailers, including pharmacies and lottery agents.

Vivo can be a practical choice for itineraries that extend beyond Brazil’s main coastal cities. Check its coverage map for specific inland or remote destinations before relying on one network for the whole trip.

Claro: The best for cities and 5G

Claro has strong coverage in Brazil’s major cities and a large physical retail network, which is useful for tourists who need help registering a prepaid SIM with a passport.

Its Prezão package costs R$30 (around US$6), is valid for 30 days, and currently includes 15 GB, with 12 GB for general data and 3 GB for YouTube, plus unlimited WhatsApp and domestic calls. Smaller packages are available for shorter stays. 

Claro also performs competitively on 5G and recorded the fastest average 5G upload speed in Opensignal’s January 2026 report. The service might be a good option for city-focused trips to São Paulo, Rio de Janeiro, Belo Horizonte, Salvador, and other major cities.

TIM: Competitive data pricing

TIM’s current prepaid offer provides up to 16 GB for R$30 (around US$5.90) over 30 days, including 12 GB in the main package and 4 GB for social networks. TIM’s Pré XIP package also includes WhatsApp messaging, although voice and video calls are excluded from that unlimited-app benefit.

TIM performed particularly well for reliability and 5G availability in Opensignal’s January 2026 testing. It’s a competitive option for city-based and multi-stop itineraries, although coverage can vary away from urban areas and main highways.

Brazilian SIM cards with unlimited data

“Unlimited data” on Brazilian prepaid plans often applies only to specific apps rather than all mobile use. Claro’s Prezão package includes unlimited WhatsApp alongside a fixed general data allowance, while TIM’s Pré XIP includes WhatsApp messaging but excludes voice and video calls.

Saily’s unlimited Brazil plan works differently — it provides 3 GB of unrestricted-speed data per day, followed by unlimited data at up to 1 Mbps for the rest of the day. A 15-day plan currently costs US$48.99.

Check exactly what “unlimited” covers before choosing a plan — unlimited WhatsApp is very different from unlimited general mobile data.

How much does a SIM card cost in Brazil?

A prepaid SIM card in Brazil with a usable data package generally costs around R$25-75 (roughly US$5-15).

The price depends on the data allowance, validity period, and extras included. Vivo, Claro, and TIM currently offer plans around R$30 (about US$6) for approximately one month of service, making local mobile data relatively inexpensive if you can complete the registration process.

Travel eSIMs cost more per gigabyte but remove the store visit and registration steps. Saily’s Brazil plans start at US$3.99 for 1 GB over seven days, while 3 GB for 30 days costs US$9.99.

A local prepaid SIM therefore offers better value for heavy data use and when you need a local phone number, while an eSIM may be worth the higher per-GB cost if you want connectivity arranged before landing — without a store visit or registration.

Where to buy a SIM card in Brazil

If you want to buy a SIM card in Brazil using a foreign passport, go to an official Vivo, Claro, or TIM store. SIMs (or “chips”) are also sold through pharmacies, supermarkets, newsstands, and other retailers, but buying one doesn’t necessarily solve the registration issue. A tourist SIM card still needs to be registered correctly if it uses a local Brazilian prepaid line. 

An official store can register and activate the line and help confirm that mobile data works before you leave.

At the airport: GRU, GIG, SDU, BSB, and CNF

International travelers commonly arrive through São Paulo/Guarulhos International Airport (GRU), Galeão International Airport (GIG) in Rio de Janeiro, Rio’s second major airport Santos Dumont Airport (SDU), Brasília International Airport (BSB), or Belo Horizonte/Confins-Tancredo Neves International Airport (CNF).

Keep in mind that you might not find an official Vivo, Claro, or TIM store open when you land. Airport retail outlets change, and current directories don’t consistently show official carrier branches at all five airports. Galeão, for example, currently lists Aerochip, a third-party mobile retailer, rather than a clearly identified Vivo, Claro, or TIM store. Airport mobile retailers also tend to keep normal retail hours. 

An official airport carrier store can be convenient because staff can handle passport registration as soon as you arrive, although airport outlets may offer fewer prepaid plans than larger city branches. If you buy a SIM card at the airport, ask staff to activate it and confirm that mobile data works before you leave. 

If the available plans are limited, the store cannot register your passport, or you arrive outside opening hours, wait until you reach an official carrier store in the city.

In carrier stores and shopping malls

For most foreign visitors, an official carrier store in a shopping mall is the most straightforward  place to get a Brazilian prepaid SIM card. Vivo, Claro, and TIM have staffed stores throughout major cities, and Claro specifically directs foreigners without a CPF to its physical stores for passport-based activation.

Bring your passport and accommodation details. Staff can register the SIM, activate the line, and load your prepaid package. Before leaving, switch off Wi-Fi and confirm that your SIM card and mobile data work properly. 

Beware that English may not be widely spoken outside major tourist areas. Having the phrase “chip pré-pago para turista” and the plan you want written on your phone can make the process easier.

Online and before you travel

Buying a prepaid Brazilian SIM before leaving the US doesn’t get you around registration. Every prepaid line in Brazil — whether bought from Vivo, Claro, TIM, or a third-party seller — must be registered with a passport (or CPF, if you have one) before it fully works. Some international sellers pre-register or handle activation for you, but don’t count on it — check with the seller, and be ready to complete registration yourself once you land.

A travel eSIM is easier to arrange in advance. You can install your eSIM before you travel and keep it switched off until needed, avoiding a setup attempt after landing without a reliable internet connection.

eSIM for Brazil: The route with no CPF requirement

An eSIM is a digital SIM built into a compatible phone, allowing you to install a mobile plan without inserting a physical SIM. For travelers who mainly need mobile data, a travel eSIM can serve the same purpose as a data SIM card without the local registration process. 

With a Saily eSIM for Brazil, you can choose and buy a data plan before departure without a CPF, passport registration at a Brazilian carrier store, or a conversation in Portuguese at the counter. The plan will start working automatically after you arrive in Brazil.

Current Saily Brazil plans include 1 GB for seven days at US$3.99, 3 GB for 30 days at US$9.99, 5 GB for US$13.99, 10 GB for US$24.99, and 20 GB for US$39.99. Unlimited plans are also available.

Saily offers data plans in more than 200 destinations, which can be useful if Brazil is one stop on a longer trip. Every Saily plan also includes security features such as an ad blocker, web protection, and a virtual location.

To use an eSIM, your phone must support eSIM technology and be carrier unlocked. Many iPhones from the iPhone XS generation onward and recent Google Pixel and Samsung Galaxy models support eSIM technology, although compatibility varies. 

Once your phone’s sorted, consider the phone number question. Saily’s standard Brazil data plans do not give you a Brazilian mobile number. You can, however, get an optional eSIM with a phone number, which provides a US number. A physical SIM card may therefore suit longer stays or travelers who need a Brazilian phone number for local services and SMS verification. For a shorter trip where mobile data is the priority, an eSIM helps you avoid much of the friction involved in buying and registering a local SIM.

If you are comparing options for internet in Brazil, the choice usually comes down to data needs, whether you require a local number, and how much setup you want to do after arrival. If you’re still weighing your options, comparing an eSIM vs. physical SIM card before choosing is a good place to start.

How much data do you need for a trip to Brazil?

Your ideal allowance depends on how long you are staying and how you use your phone. Messaging and occasional browsing consume relatively little data, while video, hotspotting, and frequent social media uploads use considerably more. Our guide to how much data you need offers a more detailed breakdown.

WhatsApp is widely used in Brazil by hotels, restaurants, tour operators, drivers, and other businesses. Simple text messaging uses little data, but voice notes, photos, video, and calls add up.

Multi-city trips can also increase usage because navigation, transport apps, translation, and travel research run throughout the day. Consider moving up one data tier if your itinerary covers several cities or regions.

Quick recap: How to stay connected in Brazil

The best option depends on your trip.

• If you want to avoid local registration and have mobile data ready on arrival, choose a Saily eSIM. 

• For a Brazilian phone number, buy a prepaid SIM card from an official Vivo, Claro, or TIM store and take your passport.

• For inland or remote travel, compare carrier coverage at your actual destinations before choosing.

• For a longer or data-heavy stay, a Brazilian prepaid SIM usually offers more data for the money.

• For a wider regional trip, consider an eSIM for Latin America or a SIM card for South America.

• If Colombia is also on your itinerary, compare your options for a SIM card in Colombia.

For most short-term visitors who mainly need data and want to avoid local registration, Saily offers a simpler setup — you can download the Saily eSIM app before departure.
