Suspended account

You can dial #227 from your Koodo phone to pay the overdue balance. It works even when the line is suspended.

As well, you can pay through your bank's online banking without logging in to Self Serve, just allow 3-5 business days for the payment to get to Koodo. Once the payment is received your service should be restored within an hour, restart your phone after that.

For the Self Serve login, I wonder if it gives you the option to get the verification code by email instead of SMS. If you can get in, you can pay right away by card or check if you are eligible for a payment arrangement (up to 3 payments)

You may want to schedule a callback through Koodo Assist and speak with a rep to see if there is any way to get back into your Self-Serve account. https://Koo.do/Chat 

Once you are able to log in, you may be able to set up a payment arrangement or pay the full balance with your credit card. https://www.koodomobile.com/en/help/payment-arrangements
