The 'unfrozen ATPL' isn't actually a licence given to you. When you get your first flying job (assuming you're thinking about airlines) you fly for that airline, post type rating, on your blue CPL until you have 1,500 hours where on passing your next proficiency check you're able to send off to the CAA who'll give you a lovely green licence which is known as an ATPL.
..but in future, please use the search function and find out the answers to your questions before making a new post because it's probably been answered before.
Good luck, S88
