How hard is it to cancel O2 Czech Republic?

O2 Czech Republic customers can cancel by calling the free line 800 02 02 02 (Mon–Fri 8–19), visiting any O2 store, sending a written request by mail, or (for business) emailing [email protected]. A 30-day notice period begins the day after O2 receives the request, with service ending on the last day of that period. Contracts cancelled within the first 3 months may incur a flat-rate early-termination fee of 5% of the remaining contractual payments; device instalment balances are separately invoiced. There is no documented self-serve online cancellation through Moje O2; number portability requests (OKU code) can be initiated there, but full contract termination requires phone, store, or mail.

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.
