Where you come across it. Conversations about "where to get an account with no maintenance fee", deposits, buying certificados de aforro.
There are few branches, and they are in the big cities: everything else is done through the website and the app. A free account does not mean a free card: the card carries an annual fee. And bear in mind that money in your account and securities bought through the bank are protected differently: deposits by the Fundo de Garantia de Depósitos up to €100,000, securities by the Sistema de Indemnização aos Investidores up to €25,000. The name is written in various ways: BiG, BIG, Banco BIG.
