Internet in Brazil: coverage once you leave the coast

Brazil looks manageable on a map and is not. This guide is about the two things that catch travellers out: coverage disappears as soon as you leave the coast and the big cities, and the distances are so large that flying is not really optional. Both change how much data you need and when you will need it.

How to get online in Brazil

Roaming with your own carrier

Brazil sits in the expensive zone of most tariffs: a daily pass with little data, or pay per use. For a three-week trip it does not add up. Check your tariff before flying.

A Brazilian prepaid chip

You can, and without a CPF: the rules accept a passport to register a tourist prepaid chip, and all three carriers have visitor products. They usually also ask for proof of accommodation. The catch is twofold: you have to go to an official shop — kiosks sell the chip but cannot sort out activation — and Brazilian carriers’ eSIMs are almost always designed for contracts, not tourist prepaid.

Travel eSIM

You buy the days you will be there, install the QR at home on wifi and land connected to a Brazilian network as a visitor. Your home line stays in the phone with its data off, for bank texts. In a country where the first journey is almost always an Uber from an enormous airport, walking out of the terminal already connected is worth more than it sounds.

Real coverage: who covers what, and where it ends

Three networks split the country: Vivo, Claro and TIM. Oi sold its mobile operation in 2022 and no longer has its own network, so discount it. 5G is in every capital and spreading through mid-sized cities; deep inland what you get is 4G, and sometimes 3G.

Good: Rio de Janeiro, São Paulo, Salvador, Recife, Fortaleza, Belo Horizonte, Curitiba, Florianópolis, Porto Alegre, Brasília, Manaus city, Foz do Iguaçu and the motorways of the southeast.

Where it ends, whichever carrier you are on:

• The Amazon: Manaus has normal coverage. Out on the river, at the lodges and in riverside villages, do not count on it. The whole region’s connectivity hangs on very few fibre routes, and when one breaks half the Amazon notices.
• Pantanal and the Transpantaneira: kilometres of dirt road with nothing. It is one of the clearest places to see that the problem is not your plan.
• Chapada dos Veadeiros: in Alto Paraíso and Cavalcante the phone shows signal, but a message can take hours to send.
• Lençóis Maranhenses: weak across the whole area; Vivo usually holds up best.
• Chapada Diamantina and Bonito: fine in the towns, nothing in the canyons and on the trails.
• Fernando de Noronha: the island has coverage and even 5G, but it is a case apart and worth checking which network your plan uses.

And as always: the eSIM connects to Vivo, Claro or TIM — it brings no network of its own. Where there is no mast, no eSIM works, ours or anyone else’s.

The distances, which nobody estimates correctly

This is the section that saves the most trips. On a map, Brazil looks manageable. In hours, it does not:

Route	By air	By bus
Rio - São Paulo	45 minutes, departures constantly	—
Rio - Salvador (about 1,970 km)	Under 2 hours	28-33 hours
São Paulo - Foz do Iguaçu	Under 2 hours	16-18 hours
Manaus - Rio	About 4 hours	No practical overland route

Translated into connectivity: you will spend a lot of time in airports and on buses, which is exactly where data goes and where the advertised wifi does not appear. And you will cross areas with no coverage between one city and the next, so the ticket, the map and your accommodation address need to be downloaded before you board.

How much data you need

Type of trip	Typical use	Plan that fits
Cities and beach: maps, transport, messaging	400-600 MB a day	5 GB for a week
The above plus social posting daily	800 MB - 1.2 GB a day	10 GB for two weeks, or unlimited
Lots of flights, video and long waits	Over 1.5 GB a day	Unlimited by days

The breakdown app by app is in how much data do I need for a trip.

Installing the eSIM and landing connected

1. Compatibility: dial *#06# and look for the EID; the phone must be carrier-unlocked. List by brand on compatibility.
2. Buy for the days of the trip: validity starts with the first connection in Brazil.
3. Install at home on wifi. Name it “Brazil”.
4. Lines: your home line for calls and texts with its data off; the eSIM as mobile data with roaming on.
5. On landing: turn off airplane mode and wait to see “Vivo”, “Claro” or “TIM”. Order your car from inside the terminal.

Every menu, step by step, in how to install an eSIM.

Apps people use in Brazil

• Uber and 99: both work in every large city and it is worth having both. At night, always an app rather than a street taxi.
• Google Maps with each city downloaded before you arrive.
• WhatsApp: everything happens there in Brazil, from booking the pousada to asking for the bill. Your own number works fine.
• iFood for food; ClickBus for long-distance buses, which take foreign cards without trouble.
• Payments: an international card for almost everything, even small stalls, plus some cash in reais for beaches, markets and small towns. At ATMs, charge in reais and decline conversion to your own currency. The 10 % taxa de serviço on restaurant bills is optional by law, though paying it is the norm.

Connectivity tips

• Before the Amazon, the Pantanal or any chapada: maps downloaded, power bank, and your route told to your accommodation.
• In airports there is decent wifi and a lot of dead time: use it to download rather than burning your plan.
• Overnight buses advertise wifi that rarely works.
• Bank verification texts arrive on your home line, which stays active and costs nothing to receive on.
• If the trip continues to Argentina, Uruguay or Paraguay, a Brazil-only plan stops at the border: look at regional plans.
