The short answer
Brazil's main mobile carriers are Vivo, Claro, and TIM. Getting connected is straightforward, but one thing is non-negotiable: prepaid SIM cards require real-name registration with a CPF. Home internet is widely available over fiber in most cities. Specific plan prices change constantly and were not verified for this guide — check the carrier's current offers before buying.
Prepaid SIM (chip pré-pago)
Prepaid is the simplest start for newcomers:
Buy a chip (SIM card) at a carrier store, supermarket, pharmacy, or kiosk.
Register it with your CPF — real-name registration is required, so have your CPF number ready.
Top up (recarga) at the same outlets, via the carrier's app, or online once you have a Brazilian payment method.
Coverage varies by region and carrier — ask locals which network works best in your neighborhood, especially outside major cities.
Postpaid plans (pós-pago)
Contract plans usually require a CPF plus proof of address, and sometimes a Brazilian credit history — which newcomers lack. They may ask for a deposit or restrict you to prepaid at first. If you are staying long-term, compare postpaid offers once you have local documents and a payment history.
eSIM and short stays
If your phone supports eSIM and your home carrier offers affordable roaming, that can cover your first days while you sort out the CPF. Whether Brazilian carriers sell eSIMs to prepaid customers varies — ask in store.
Home internet (banda larga)
Fiber-optic broadband is widely available in urban Brazil, and most households get online that way. Signing up normally requires a CPF and a Brazilian address; installation appointments are scheduled after the contract. Speeds and prices differ by provider and neighborhood — compare current offers locally, as plan prices were not verified for this guide.
Frequently asked questions
Can I buy a SIM card without a CPF?
No, effectively not. Prepaid lines must be registered to a CPF, so get your CPF first — it is free and can be obtained at a Brazilian consulate abroad.
Which carrier is best?
Vivo, Claro, and TIM are the national options. "Best" depends on where you live — coverage differs by neighborhood, so ask people nearby rather than trusting national maps.
Do I need internet at home, or is mobile data enough?
Many newcomers start with mobile data only. If you work from home or stream a lot, fiber broadband is the standard solution and is widely available in cities.
