New O2 esim with contract - verification not possible

Is it about prepaid or postpaid?

Have you been to an o2 Shop? They should be able to verify your identity with the documents you have there.

Its a prepaid contract. I havent been to an O2 shop, will try going today.

If you ordered the card online, you do not need to go to an o2 shop. Register online instead.

I have ordered it online via mediamarkt, i have already tried online registeration and verfication via webId. They are not able to verify my passport and fiktionsbescheinigung, they said to instead connect with esim provider - which is O2. 

  Will going to the shop physically help at all?

MM activates the SIM card. And, as previously mentioned, an o2 shop is not the right point of contact.

An o2 Shop can verify the identity to activate a prepaid SIM as well, ​@Bumer. Whether they are prepared to do it is another question. Or possibly try an o2 stand in Mediamarkt.

Ok, so I went both to O2 store and a O2 stand in Mediamarkt. Sadly the O2 store redirected me to Mediamarkt and The O2 stand in Mediamarkt told me they cant do anything for an online contract. And that I can only try online. 

Whereas the online verification told me to visit O2 store! 

This is such a broken system. Do they not want new customers?! This is so frustrating

As previously stated, registration and identification can only be completed where you made your purchase.
