You can cancel any time from your account page. Your plan keeps working until the end of the period you already paid for, and you are not charged again.
Plan words stay usable until the end date and end with the plan. Top-up words and sign-up words never expire and stay on your account after the plan ends.
Before the end date, open My account and click Resume plan. Your plan continues on the same billing date.
If you want a refund as well, see the refund policy.
