fidelização

período de fidelização — the period during which you commit to staying with the provider

A telecoms contract in which you promise to stay for a set period and in return get a lower price, free installation, a router or a set-top box. The legal maximum is 24 months. The provider must also offer contracts with no tie-in at all and show how the price differs for 6, 12 and 24 months. It can impose a new tie-in (refidelização) only if it gives you something new in return, named and costed in the contract, and only with your express consent.

Where you come across it. A contract for mobile service, home internet and TV; a line on your monthly bill.
The date the tie-in ends and the amount you would be charged for leaving today must appear on your monthly bill — that is where to look, not in a contract from two years ago. It is up to the provider to prove that you agreed to the tie-in.
