I believe so. The writing is such that you use it, but you cannot. But reps here have repeatedly answered you should be able to use the 16 dollar a day rate thereafter, and even re-add the travel pass if you need it again in the same billing cycle.

Hi ​@Gwg you can continue to use daily Easy Roam once the pass expires. You can find out more information here https://www.koodomobile.com/en/help/europe-easy-roam-travel-passes

Make sure you add the Easy Roam add-on to your account to avoid pay per use charges as it is not currently active.
