new phone plan

Just to confirm — do you have a Tab (device balance) on the second line? An active Tab can prevent a plan change from going through.

As well, that 5G 100GB Canada-US plan may be a promotional offer with its own eligibility criteria, so it won't always appear on both lines (each line is separate — Koodo plans aren't shared). Open Change my plan in Self Serve and read "The Legal Stuff" at the bottom of that page to see the requirements — https://www.koodomobile.com/en/help/changing-your-rate-plan

If there's no Tab and the plan still isn't offered on the second line, that offer is likely tied to the line it appeared on. In that case, make sure you're logged in here with your Koodo credentials and someone can ask  a rep in this thread.

I clicked on Tab balance and it says I do not have one. 

The legal stuff doesn’t say anything that I can only apply one play per phone number. 

I would hope it would be offered for ALL Koodo customers. 

 Are you logged into the community with your self serve account?

If so we can flag a rep for you.

I cant see why they wouldnt be able to change your plan to match the plan on the other line.

yes I am logged in. I would like to add the same plan to both my cell phone lines.
Thanks for your help
