Unable to Create O2 Account – Ongoing Issue for Over 3 Months

Where did you buy the prepaid card?

I bought it from the O2 shop in Heidelberg 

Is the card active? Are you trying to register the phone number there?

Yes , card is activated also. Im making and receiving calls also. The link you have shared I have been trying to create account through that but its not working.

The account may already be created; use this link:

https://login.o2online.de/signin/XUI/?service=ForgotPassword#login/

Username = Phone number

Please do not mark every answer as the solution!

I have tried this link also, it’s not working also.

My apologies.

What does *doesn't work* mean? What does it say?

When Im putting my number as Username it says : The verification code has been sent. But I’m not getting any code . 

Do you receive any other text messages?

Normally when Im trying to register it is sending my code on SMS but with this forgot password its not sending anything 

Try using a different browser for registration, preferably on a desktop PC via an anonymous tab!

I tried using different browsers on desktop PC via anonymous tab but its not working either

It would be more helpful if you could provide screenshots?

I have tried to create account from different browsers via PC but it’s redirecting again to this page.

What exactly do you enter as your username?

As you have mentioned above also; Username = Phone number. So I’m using contact number.
