How Does SIM Card & Internet Work in Brazil?
Last verified: 2025-06 · Americas
1The Quick Answer
Buy a prepaid SIM from Claro, TIM, or Vivo at the airport or a phone shop — bring your passport as it is legally required for SIM registration.
2What You Need to Know
Brazil's three main mobile carriers are Claro, TIM, and Vivo, all offering prepaid (pré-pago) SIM cards with data plans at airports, carrier stores, and supermarkets. You must present your passport for registration, which is a legal requirement. Coverage is excellent in major cities and coastal areas but can be patchy in the Amazon and remote rural regions. International eSIMs such as Airalo work in Brazil and are convenient if your phone supports eSIM — activate before arrival.
3Practical Tips
Practical Tips
- 1Claro generally offers the best coverage in the Amazon and northern regions — choose Vivo or TIM for the best coverage in the urban south and southeast.
- 2A 15GB prepaid data plan typically costs R$40–60 and lasts 30 days — far cheaper than roaming on your home carrier.
- 3WhatsApp is the primary communication tool for almost all Brazilians — having a working SIM with data means you can contact hotels, tour operators, and local contacts via WhatsApp.
