If you don't have a different provider SIM Card to put in to bring up the unlock code input you could try this I just found it online so never tried personally, so if you do try and it works feel free to come back and let us know if it worked or not to help others, thanks. Samsung Galaxy S2, S3,...
You can send Koodo a private message to their FB page where they can swap the SIM for you, it could take a little for them to get back to you if busy. That or call from another phone to customer service if you need it activated immediately. Dial 1-866-995-6636
