    Overall excellent experience!

    Overall excellent experience! I ordered two sim cards from O2 and I was surprised by the speed of delivery. My business trip to Europe felt so much easier knowing to have internet upon arrival. I only struggled changing a few settings on my phone but the online support helped me out a lot!

    Worked very good in all European countries…

    The Prepaid GO CARD by O2 worked very good in all European countries i went during this summer. The 10GB data were more than enough – the speed was super satisfying. I will definitely use it again when I come back to Europe. Whenever you have a problem, just contact their customer support – they’re super responsive and helpful.
