critical issue with my o2 Prepaid account access.

Hello,

I am having a critical issue with my o2 Prepaid account access.

Previously, I was registered and could use the "Mein o2" app without any problems. However, a few days ago, the app logged me out. When I tried to log back in, nothing worked.

I then tried to recover my password via the website, but without success. I even requested and received a temporary password/code via post (paper mail), but when I enter it, the system keeps saying it is incorrect. It seems my login credentials and profile are completely out of sync.

Out of desperation, I tried to re-register. When the system asked for my PUK code, I entered the exact PUK printed on my original SIM card holder, but the system rejected it as incorrect.

It feels like my backend profile is completely broken or locked. Could an o2 moderator please look into my account database profile, reset the online registration lock, and help me regain access?

Thank you!

First, compare your SIM card number with the one on the SIM card holder.

Hi ​@peaced 

welcome to our community. Pleasure to meet you. 🙂

Unfortunately we don’t have any access to your data because you are signed in here as a prospect. 

We recommend to use the Prepaid-Chat

Hello, thank you for message. But the issue is I can’t even login to the prepaid chat. Because anytime I try to login with my number, it sends the code but it doesn’t go further an error message always appear. So I don’t have any way to access the prepaid chat.

Alright, where exactly did you purchase the SIM card? Registration for *Mein o2* takes place during the identification process!

That is not so nice when you cannot move forward with your Prepaid SIM, ​@peaced, did you purchase the SIM Card online or in one of our shops or via another channel?

Best Regards,

Gerrit
