How hard is it to cancel Oi?

Oi scores 43/100 (grade D) for how clearly it documents cancellation in the BR, a poorly documented cancellation policy. Cancellation is available via phone, in person.

Last reviewed 2026-06-06 · Documented-Policy tier · grade D

Oi (now primarily B2B after selling its fiber/residential internet operations to NIO in 2025) offers cancellation of its remaining fixed-line residential service (Oi Fixo) exclusively by phone: 103 31 for residential customers or 0800 031 0800 for business accounts; in-person store visits are also an option. No self-serve online or app-based cancellation is offered for consumers. If a plan is cancelled within a 12-month loyalty/fidelity period, a proportional penalty on the discount granted applies (base value of R$300 pro-rated to remaining months); for plans without fidelity, no cancellation fee applies. Charges are billed proportionally through the last usage period following the cancellation request.

Evidence

Scope & fairness

This is the Documented-Policy tier: it measures how clearly the cancellation policy is published (cited, dated facts), not the behavioural experience of cancelling (Verified-Flow audit pending). Every company is scored on the same five dimensions with the same published weights, scores cannot be bought or removed. It is opinion grounded in disclosed facts, and not legal advice.
