Hi Diana - sorry, but I'm not sure I understand your question. Are you looking to keep your TELUS phone number and bring it over to Koodo? Or do you have an account with TELUS and also with Koodo that you're trying to link?
If you want to bring your number over, you just need to log into your self-serve account, select 'change phone number' at the bottom of the page, and then follow the steps to port your number in. If that's not what you're looking to do, please explain a bit more and we can try to help.
