HI @leyosu21 Yes , changing sim card is easy
But what you meant by you are waiting the account to be deactivated? What did you do to disable the account? You only need to login to My Account and click Lost/Stolen to temporary suspend the service
Then get a new sim card from a Telus or Koodo store near you
After you got the sim card, you logon to My Account, un-suspend your account (make it out of Lock/Stolen status and active again)
Then go to the profile page, edit account information and then you can enter the new sim card number to link it with your current account.
