Hey @Francesco,
Our service is accessible worldwide, and you’ll be able to manage your account from every point of the world. You don’t need to create a new account, nor sign a new contract. Instead, you may reach our team, and we’ll update your residential address.
As of the list of the supported countries - there is quite a simple way to check this: go on our page, tap on the “Open account” button and select the country you’re interested in. You’ll see a notification in case the country is not supported by us.
