Activating SIM Cards for Foreigners: how it works in Brazil — first-hand
Short answer
To purchase a Brazilian SIM card, you generally need a CPF tax ID, which can be obtained online or via a local resident. For tourists without one, buying a SIM from an official store or newspaper kiosk and calling customer service to activate it using passport details is a common alternative. Alternatively, eSIMs offer a more convenient, CPF-free solution for short-term travel.
From real experience
To purchase a local SIM card in Brazil, a CPF (Cadastro de Pessoas Físicas - Brazilian individual taxpayer registry identification) is mandatory.
Travelers without a CPF can either obtain one remotely before the trip or visit large shopping malls (e.g., RioSul) where store employees may assist in activation. eSIM is suggested as a more convenient alternative for short-term tourists.

If you are a foreigner in Brazil unable to activate a Vivo SIM card via the app due to regional store restrictions (e.g., Russian App Store), call customer service at 1058. Say: 'Quero ativar o chip como estrangeiro, sem CPF.' Alternatively, consider carriers like TIM or Pague Menos (which offers 5GB/month for 30 BRL via their network).

Foreigners face difficulties acquiring a local SIM card in Brazil without a physical Brazilian identification document.
Options include:
1. Asking a local resident to register a SIM card in their name. This has been successfully done, sometimes for free.
2. Obtaining a CPF (Cadastro de Pessoas Físicas) and registering the SIM card independently for long-term stays.
3. A workaround reported by one user involved generating a fake CPF online after their legitimate CPF was rejected, which successfully activated the SIM.
4. Using an eSIM is also a convenient alternative.

A local prepaid SIM card in Brazil (e.g., TIM) is very affordable (approx.
20 BRL/month) and can be bought at newspaper kiosks ('banca') or border pharmacies (e.g., in Foz do Iguaçu). However, activation requires a CPF (Brazilian tax ID). Advise travelers to register for a CPF online prior to their trip or seek help from local residents for activation. Note that TIM's coverage can sometimes be spotty in certain areas.

When purchasing a TIM SIM card in Brazil, it is highly recommended to buy it directly from an official TIM store.
Buying from general shops/kiosks can lead to activation issues, even if you possess a CPF. While activation might be possible by contacting customer service directly and providing personal details, SMS-based registration may not be an option, and official stores might refuse to assist with SIMs purchased unofficially.

It is possible to purchase a physical tourist SIM card in Rio de Janeiro at a newspaper kiosk inside the RioSul shopping mall without a CPF.
The process involves providing passport details to an English-speaking operator via phone, which activates the card. The reported cost was 70 BRL. After obtaining the SIM, Uber accounts may still require verification (passport photo and selfie) if they initially ask for CPF or a credit card.

In Brazil, major telecom brand stores rarely sell mobile plans to tourists without local residency (CPF/VNJ).
To obtain a prepaid SIM card ('chip pré-pago'), buy it at a street newsstand (banca de jornal) for around 20 BRL. It is highly recommended to activate it immediately with the seller's help to verify it works. Balance top-ups can be done at local pharmacies.
