All shipping methods before user logged in

[ermes]

Hi, there is a method to show all shipping methods before the user logged in or inserts billing/shipping informations?
My shipping methods are 3:

- Express courier Italy - (only for italy)
- Express courier Europe - (only for europe)
- Express courier World - (already visible for all because the field "Countries" in the configuration is empty)

Can you help me, please?
Tnx very much!
