Depends on what you prefer. If you’re not in a rush, you could just wait for that time. If you are, you may as well just create a new account and port over to Koodo once you get the sim cards. All phones come with sim cards by default with Koodo, so it’s all good. It’ll all setup the same just fine, regardless of the phones you have.

The thing about this is that you will likely need to go to your local Koodo store to put both of your lines on the same account.

When you sign up online, you can only put one line at a time. In order to consolidate both lines into one account, you will either need to spend $45 on the transfer of ownership to put all of your lines together into one account, or even worse, pay the $50 connection fee for each line to get it done in store. https://www.koodomobile.com/en/help/transfer-of-ownership-town

If you still want to proceed online, it would be best to create a line and wait for 45 days before adding a new line to your account. That way, you won’t have to waste money to get this sorted out.
