This app doesnt works for basic plan...
i dont have a specific carrier and i just want locate postcodes zone in Paris.
Unable to do that with this app..
Hi, the app works with all plan types but you will need the Realtime Carrier Rates module. This is available by default on the Advanced and the Plus plans and is a restriction put in place by Shopify.
You can also get Realtime Carrier rate free of charge by switching your store to an annual billing plan.
Unfortunately you have left a 1 star review based on a platform limitation and not the functionality of the app. We would be happy to work with you to get this resolved.
