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.
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.

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.
