Roaming Charges in Brazil
Using international roaming in Brazil can be quite expensive, as many foreign carriers charge high fees for calls, messages, and data usage. Depending on your provider, roaming costs may vary, but it’s common to see hefty surcharges for each MB of data consumed. In some cases, travelers have reported paying exorbitant amounts for basic internet access, making it essential to plan ahead.


To avoid an unexpectedly high bill, it’s important to explore alternative options for staying connected while traveling in Brazil. Many travelers opt for local SIM cards, eSIM solutions, or portable Wi-Fi devices to maintain internet access without the risk of excessive charges. Additionally, some credit cards and mobile plans offer international roaming packages, so it’s worth checking with your provider before your trip.
How to Get a Travel SIM Card for My Trip to Brazil
One of the best ways to save on roaming costs is by purchasing a travel SIM card before your trip. Many companies offer international SIM cards that work in Brazil, providing affordable data packages and local call options. These SIM cards are available online and can be shipped to your home before you depart, ensuring you have connectivity as soon as you land. Alternatively, you can buy a travel SIM at international airports upon arrival. Some of the popular providers for travel SIM cards in Brazil include Airalo, HolaFly, and SimOptions.

These companies offer prepaid packages that cater to different usage needs, from light browsing to heavy data consumption. Before purchasing, ensure that your phone is unlocked and compatible with international SIM cards. Additionally, check if the SIM provides both data and voice services, as some travel SIMs are data-only. Having a travel SIM can significantly reduce your mobile expenses while ensuring a seamless connection throughout your stay.
How to Get Unlimited Internet Data for My Phone in Brazil
For travelers who need unlimited internet access, there are eSIM options that provide unlimited data plans for Brazil. Services like Airalo and HolaFly offer digital SIM cards that can be activated instantly, eliminating the need for a physical SIM. This is a great solution for those who want a hassle-free way to stay connected. Additionally, major Brazilian telecom companies such as Claro, TIM, and Vivo offer prepaid plans with generous data allowances that can be recharged as needed.


These local providers often have promotions for tourists, offering weekly or monthly unlimited data packages at reasonable rates. Another alternative is renting a portable Wi-Fi device, which allows multiple devices to connect simultaneously. This is particularly useful for families or business travelers who need consistent internet access across multiple gadgets. Be sure to compare plans and providers before choosing the best option for your trip.
Can I Buy a Brazilian Line During My Trip?
In Brazil, tourists face difficulties buying a SIM card because most mobile carriers require a CPF (Cadastro de Pessoas Físicas), a taxpayer identification number issued by the Brazilian government. This requirement exists due to regulatory, security, and financial reasons.
The government enforces strict telecommunications regulations to prevent fraud, identity theft, and illegal activities, ensuring that all phone numbers are linked to identifiable individuals. Since a CPF is only issued to Brazilian citizens, legal residents, or foreigners with a valid reason to obtain one, most tourists do not have it, making SIM card registration difficult.

The CPF requirement is also a measure against phone-related fraud, such as SIM cloning and unauthorized transactions, which have been issues in Brazil. To combat this, telecom companies must comply with rules set by Anatel (Agência Nacional de Telecomunicações), which mandate proper identification of users. Furthermore, mobile carriers integrate CPF numbers into their billing and customer management systems, using them for fraud prevention, marketing, and linking accounts to digital services such as mobile banking. Without a CPF, tourists may struggle to activate a SIM card, register for promotions, or even add credit through certain online payment methods. Although some workarounds exist, they are not always reliable. In some cases, major carriers like TIM and Claro allow tourists to register a SIM card with a passport instead of a CPF, but this is inconsistent and varies by store.
Another option is to purchase tourist-friendly SIM cards at international airports, where some stores offer prepaid plans without requiring a CPF, although these options tend to be more expensive. Alternatively, travelers with eSIM-compatible devices can buy international or local eSIM plans online, avoiding the need for a physical SIM card and CPF registration. Some tourists also use a Brazilian friend’s CPF to register a SIM card, though this carries privacy and legal risks. Overall, while the CPF requirement creates a barrier for tourists, it is primarily intended to regulate telecommunications, enhance security, and prevent fraud. Those visiting Brazil should plan ahead by exploring alternatives such as eSIMs or airport SIM card purchases to ensure connectivity without unnecessary complications.
