Hi there,

So the pass is a one time use then you will need to purchase another. Once your first 7 day pass is used up you will then be charged the daily roaming fee rates of $14 a day unless you get another pass.

You can only purchase another of the same pass if it either expires after 30 days for the USA or if the 7 days of an existing US pass is used up. Only after that can you buy another pass, not before. More information can be found in the link below. I hope this helps
