Yes, you can use Ay Yildiz with Medionmobile abroad. Ay Yildiz is a Turkish mobile network operator, and Medionmobile is a German mobile virtual network operator (MVNO) that uses the network of O2 in Germany.

However, be sure to check the roaming rates and policies of both Ay Yildiz and Medionmobile to avoid any unexpected charges while using your phone abroad. **
