I do not intent to provide my own passport details, but you may want to go to the forum page and give your feedback to the people that had the problem.
Yep but if you look even further into the thread it has this reply from Giff Gaff and people are still not able to lift the filter(EU or not)
"Thanks for contacting me about removing your adult bar. Don't worry I'll look into this for you now.
Unfortunately due to a change in process recently we are only able to remove the adult content bar with a full driving license number or with a valid UK passport."
