I know that when you're purchasing a traveling policy/insurance, it should be delivered to your email address. Check the SPAM or INBOX folder to locate the email, because you might have to connect to the UILTraveller website to download it. Their website contains only a login form, which I believe is the place to download the traveling policy.
Access the following URL to login once you obtain the credentials. Additionally, contact the seller and ask for instructions about UILTraveller.
