Cannot register on Mein O2 app or website to access prepaid SIM account info

Hi there,

I need help to either send me a default password via SMS or verify my email address so I can access the Mein O2 app and the O2 website. 

I am a Prepaid SIM user and I have been trying to register an O2 account on the O2 app and the O2 site, but the registration process always goes in a sort of loop and I cannot finish the process. Here is what happened when I tried to register on the app:

  1. I click Einloggen, and it directs me to a Login page
  2. I click on the Jetzt registrieren link
  3. I choose Ich bin Mobilfunk-funke and click Weiter
  4. I input my prepaid SIM phone number and click Abschicken
  5. I input the verification code received from SMS and click Verifizieren
  6. I input the PUK number and click Verifizieren
  7. I input my email address and click Bestätigungscode senden
  8. I input the verification code received in my email and click Verifizieren
  9. HERE IS THE PROBLEM: it goes back to the Login page. I input my phone number, and it asks for Kennwort. But at this point, I DO NOT have a password.
  10. I click Kennwort vergessen? and it goes to the Du hast dein Kennwort vergessen? page and I input my prepaid phone number in the Nutzername and click Weiter, and it goes to Rufnummer bestätigen
  11. I input the verification code received via SMS and click Verifizieren, and HERE IS THE ANOTHER PROBLEM: it goes to say E-Mail nicht bestätigt. 
  12. The only optioins I have now is Kennwort per Brief zurücksetzen or call the O2 hotline. But:

    1. I have a prepaid SIM, and no one asked for my address when I purchased it at your O2 official store.

    2. Your hotline for Prepaid SIM only has German service. I did manage to get through to a human after 15 minutes of waiting, but then the person asked for my SIM card holder Karten-Nr., went for a long check in silence, then disconnected the phone call. 

Just for your information, before all this drama, I had gone to an O2 store and they couldn’t fix it. They told me to the Alexa store where there was “technical support,” - and they couldn’t fix it there either. They told me to contact the hotline, and here we are in a perfect loop of dysfunctionality O2 has created for its prepaid customers. 

How hard is it to register for an O2 account to access its prepaid service on its App and website? 

So please, find a way to fix this. Please get in touch to either send me a default password via SMS or help me verify my email address so I can finish the registration process and use your app/website. I’d be happy to share my contact means in a private message. Thank you.

Hello ​@david.law,
welcome to the o2 Community. Thank you for contacting us with your query. Is your SIM card already activated and have you already verified your identity? Only then is it possible to register via My o2 or the app.
Best regards, Bianca

Hello,

Thank you for responding.

Could you define “activated” and “verify your identify” please?

What I know is:

  • I purchased the SIM at one of your official stores, and I have been using the service for a few weeks by now.
  • I can use it to make phone calls and access the Internet. 
  • My ID was used by one of your staff at the store in order to issue the prepaid SIM card

So I assume my SIM card is activated and my ID was verified. Unless you have a different definition of “activated” and “verify your identify”, in which case, please let me know.

Best.

Hello ​@david.law,

oh dear that is frustrating when a registration process ends in a loop of error messages.

Have you tried the registration also via our webpage: login.o2online.de/signin/XUI/?service=UserRegistration#login/?

Best regards,

Gerrit

Yes, I have tried the web reigstration. It goes in a loop. 

It starts here:

I chose Ich bin Mobilfunk-Kunde, entered my phone number, verfication code via SMS, PUK, email, verification code via email, then it loops back to the same place:
 

 

Honestly, I waited for three days and all I get is “have I tried registering on the web”?

Please, someone who has the techiical access, get in touch to give me a password reset and a default so I can access my account via the app, or help me verfiy my email address so I can reset my password by myself. I’d be happy to verify any appropriate personal information you need. Please esclate the case, if necessary, to save both of our time.

Once this case is resolve, I would suggest you have your web/app development team look at your business logic of the app and web and find out who delivered this substandard web app and IOS app to O2 DE. 

 

DO NOT MAKE ME WAIT FOR DAYS AND COME BACK WITH ANOTHER QUESTION TO ASK ME TO CHECK SOMETHING ON MY SIDE. GET IN TOUCH WITH A SOLUTION, NOT WITH MORE QUESTIONS. I HAVE DONE MY DUE DELIGENCE TO PROIVDE YOU THE WHOLE CASE. 

 

Thank you.
