Hello,
Sorry, you won’t be able to use it from Europe until Apple permits it. This article from Apple states:
Supported languages: Apple Intelligence will initially be available in English (US) in most regions around the world. In December, Apple Intelligence will add support for English (Australia), English (Canada), English (New Zealand), English (South Africa), and English (UK). Next year, Apple Intelligence will expand to more languages, like Chinese, French, Japanese, and Spanish.
After you have turned on Apple Intelligence, it will continue to work when you travel to other regions around the world.
For European Union residents: Apple Intelligence will not currently work if you are in the EU and if your Apple ID Country/Region is also in the EU. If traveling outside of the EU, Apple Intelligence will work when your device language and Siri language are set to a supported language.
