Brazil SIM card or eSIM for tourists

At a glance

Your three options

There are three ways to stay online in Brazil. You can keep your home number on roaming, buy a travel eSIM from abroad before you fly, or buy a Brazilian prepaid SIM card or eSIM after you land. A local number is handy if you will call restaurants or receive SMS codes from Brazilian apps. Roaming or a travel eSIM saves you the registration step.

Whichever you pick, check two things on your phone before the trip: that it is unlocked for other carriers, and, for an eSIM, that your model supports it.

The registration rule for prepaid lines

Law 10.703 of 2003 requires every company that sells prepaid phone service in Brazil to keep an up-to-date register of its users with full name, address and an identity document number or tax number. That applies to tourists as well.

Anatel, the telecom regulator, describes how it works since November 2021. You insert a new prepaid chip, the carrier sends a notice, and you complete registration on your own phone (some carriers also do it through an app or website). The online form asks for:

• a CPF (Brazilian tax number), date of birth and home postal code (CEP), which the carrier checks
• a selfie and a photo of an identity document with a photo
• acceptance of a statement that the data is true

Anatel is clear on the result: without completed registration the line is not activated. If the data is wrong or incomplete, the carrier tells you and points you to its automated line. When that does not solve it, you can complete activation in person at a carrier store by showing a personal identification document.

A Brazilian SIM without a CPF

Most visitors have no CPF, so the online route does not fit. In practice that means going to a carrier store with your passport and asking the staff to register the line there. Anatel’s page does not mention passports or foreigners, so ask the carrier which documents it accepts before you buy. Some carriers sell plans aimed at foreign visitors; their terms change, so check them on the carrier’s own site.

SIM card or eSIM at Rio airport

At RIOgaleão, Rio’s international airport, the official site lists Aerochip, a phone service point that helps travelers activate chips with data and calls. It is in Terminal 2, on the ground floor (Piso 0), in the public arrivals area, and opens from 06:00 to 22:00. If you arrive late at night, a travel eSIM set up at home or roaming will cover the ride to the hotel. Our Rio airport transfer driver meets you in arrivals, so you do not need data to find the car.

Roaming and travel eSIMs

If your home carrier has roaming in Brazil, ask about its daily rate and data allowance before you leave. Turn off data roaming in your phone settings if you plan to use only Wi-Fi or a second eSIM. A travel eSIM bought before departure is set up at home, so you do not go through the Brazilian prepaid registration; it usually gives you data and no Brazilian number.

Emergency numbers

The U.S. State Department lists the main numbers: 190 police, 191 police on federal highways, 192 ambulance and 193 fire department. Save them before the trip, along with your hotel’s number.

Quick checklist

• Check that your phone is unlocked and supports eSIM.
• Decide between roaming, a travel eSIM or a Brazilian line.
• For a Brazilian line without a CPF, plan time for a carrier store and bring your passport.
• Save 190, 192, 193 and your hotel number.
• Check entry requirements on official websites.
