Rio de Janeiro Bookings From the US Are Up 109% in 2026, the eSIM Reality
Destination eSIM · · 9 min read · By AirCarta Team
Rio de Janeiro was already a bucket-list destination for American travelers. In 2026, it's one of the fastest-growing ones, with bookings from the US up 109 percent year over year, among the sharpest increases of any international destination this year.
Quick answer: Brazil is one of the rare countries where an eSIM isn't just more convenient than a physical SIM, it genuinely solves a problem most tourists can't solve any other way. Local prepaid SIMs typically require a CPF, Brazil's tax ID number, which foreign visitors simply don't have. An eSIM sidesteps that requirement entirely.
Why This Isn't Like Buying a SIM Anywhere Else
In most countries, buying a tourist SIM means showing a passport, maybe waiting in a line. In Brazil, it's a different problem altogether: full registration for a prepaid SIM typically requires a CPF, the Brazilian equivalent of a tax identification number, something no foreign tourist has. Travelers who've tried it describe going store to store in São Paulo or Rio only to be turned away, occasionally getting lucky when a staff member or a stranger lends their own CPF to complete the registration. One traveler account describes trying three different Vivo, Claro, and TIM stores in Rio over several days before finally finding a post office employee in Leblon willing to register a SIM under their own CPF as a favor to a stranger.
It's a genuinely unusual situation. In most of the world, a tourist can walk into almost any phone shop and walk out connected within minutes. In Brazil, that's often not true. One well-documented workaround, TIM's tourist-only SIM, accepts a passport alone, but it comes with a single narrow plan option, commonly just 1.5GB for a week, and isn't stocked at every location, so finding one that carries it can itself take time you'd rather spend at the beach.
| Factor | Local Physical SIM | eSIM |
|---|---|---|
| ID required | CPF at most stores, passport-only options are limited and store-dependent | Payment details only |
| Setup time | Can mean visiting several stores before finding one that will register you | A few minutes, before you fly |
| Plan flexibility | Tourist-only options are typically limited to one small plan | Multiple data tiers to choose from |
| Where to find it | Not sold at the airport on arrival, unlike most countries | Bought online before departure |
That last row is worth sitting with. In almost every country in the world, a prepaid tourist SIM is sold right at the arrivals hall. Brazil is one of the exceptions, and it catches first-time visitors off guard specifically because they're expecting the same setup that worked everywhere else on their trip.
The Network Reality in Rio
Brazil's mobile market runs on three major carriers: Vivo, Claro, and TIM, together covering more than 95 percent of the country's mobile subscriptions. In Rio de Janeiro specifically, all three offer strong 4G coverage with 5G expanding, and independent coverage data consistently ranks Vivo as the strongest for overall nationwide reach, with Claro competitive on urban speed. For a trip that stays within Rio, Sao Paulo, and other major cities, any of the three performs well. The gap widens once you head toward the Amazon or deep rural interior, where Vivo's broader footprint tends to hold up better than the other two.
WhatsApp Isn't Optional in Brazil
This is worth knowing before you land: WhatsApp functions as essential infrastructure in Brazil, used for everything from restaurant reservations and tour bookings to everyday business communication. Showing up without reliable data for it isn't just inconvenient, it can genuinely complicate simple things like confirming a reservation or reaching a tour guide. Whatever connectivity option you choose, make sure it's active before you need to make that first WhatsApp message.
The Language Gap Makes Data Matter More
English proficiency in Brazil runs lower on average than in much of Western Europe or Southeast Asia's major tourist hubs, which means a working translation app isn't a nice extra, it's often how you order food, ask for directions, or communicate with a driver. Ride-hailing apps like Uber and 99 are the standard way to get around Rio safely, especially at night, and both need a live connection to work. None of this is unique to Rio, but it adds up to more day-to-day reliance on data than a trip to, say, London or Dublin would.
Getting Around Rio Itself
Rio's tourist geography splits roughly into the beach neighborhoods, Copacabana and Ipanema, the historic center, and Santa Teresa's hillside streets near the tram line. Coverage across all of these is consistently strong on the major networks, since they're some of the most densely built-up parts of the city. If your itinerary includes a favela tour, and many legitimate, community-led ones exist and are worth doing, going with a reputable local guide rather than arranging one independently is standard safety advice, and having working data to stay in contact with your group matters there as much as anywhere else in the city.

What Travelers Say
"Got turned away from two phone shops in Rio because I didn't have a CPF. Wish I'd just set up an eSIM before flying in."

Frequently Asked Questions
Why can't tourists just buy a SIM card in Brazil?
Most prepaid SIM registration in Brazil requires a CPF, the national tax ID number, which foreign visitors don't have. A small number of tourist-specific options exist, like TIM's passport-only SIM, but they're limited in plan choice and can be hard to find outside major cities.Does an eSIM avoid the CPF requirement?
Yes. Buying an eSIM online doesn't involve Brazil's local SIM registration process, so the CPF requirement simply doesn't apply.Which network is best in Rio de Janeiro?
Vivo, Claro, and TIM all offer strong 4G and expanding 5G coverage in Rio itself. Vivo generally has the edge for wider nationwide reach if your trip extends beyond the city.Do I really need data for WhatsApp in Brazil?
Yes, more than in most countries. WhatsApp is used for everything from restaurant reservations to tour bookings and everyday communication, so having it working from the moment you land matters more here than it might elsewhere.Why are US bookings to Rio up so much this year?
Rio de Janeiro's bookings from the US rose 109 percent year over year in 2026, one of the sharpest increases among international destinations tracked this year, alongside similar surges to Quito and Kathmandu.Is Rio safe to navigate with just an eSIM and no local number?
An eSIM covers data, including maps, translation, and ride-hailing apps, which covers most practical navigation needs. If you specifically need a local phone number, a physical SIM would be required in addition.Do I need to speak Portuguese to get by in Rio?
Not fluently, but English proficiency is lower on average than in much of Western Europe, so a working translation app matters more here than in many other popular destinations.Are Uber and 99 reliable in Rio?
Yes, both are the standard way tourists get around the city safely, and both require an active data connection to book and track rides.Is it true you can register a Brazilian SIM at a post office?
Some travelers have managed to register a SIM through Correios, Brazil's postal service, though it typically still requires someone's CPF, so it isn't a guaranteed workaround for tourists without one.Final Thoughts
Rio de Janeiro is having a real moment with American travelers this year, and it's arriving in a country where the usual backup plan, grabbing a local SIM at the airport, doesn't actually work the way it does almost everywhere else. An eSIM set up before you fly isn't just the easier option here, it's often the only one that doesn't involve begging a stranger to use their tax ID.
