I'm glad to hear you have been able to clear off your past due balance with us. In the event of a cancellation a wireless number can be reactivated if it's been cancelled for less than 60 days, do you know what date was your account cancelled? Additionally a reactivation can only be completed if the number has not been re-assigned to another subscriber.
Typically, if an account is cancelled due to non-payment, it's best to speak to Credit Operations about any potential reactivations. You can reach out to them at 1 866 346-3430. Please visit our Contact Us page and click on Billing & Payments for hours of operation as well as a link to Live Chat.
