Mobile carriers: how it works in Brazil — first-hand
Real experience of people from chats on «Mobile carriers» in Brazil — as it is, no fluff. For your case — ask Luky.
From real experience
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).
Mobile network coverage in Brazil presents challenges across operators. Tim is used by one individual, though coverage issues are acknowledged. Claro is suggested as a provider with good and affordable plans. Vivo's 'Easy' plan allows for data top-ups as needed, with 2GB costing 16 BRL per month, which is sufficient for users who primarily rely on Wi-Fi.
For tourists in Brazil, the local provider Vivo is recommended. SIM cards can be purchased at any shopping mall with a passport. Costs start from approximately 30 BRL. Roaming is generally not recommended due to high costs compared to local prepaid plans.
For UnionPay (RSHB) cards in Brazil, 'red 24horas' ATMs are widely available for cash withdrawals. Note that UnionPay may not work in certain areas, such as the domestic departures zone at GRU airport. For local SIM cards, Tim and Vivo are recommended operators, with users reporting similar service quality.
