Добрый день, 

Я обращаюсь к вам, потому что уже неделю не могу войти в свой аккаунт My O2. При попытке входа постоянно получаю сообщение об ошибке.

Не могли бы вы проверить, не заблокирован ли мой аккаунт, и помочь мне восстановить доступ?

Lösung von Liudmyla64

Good afternoon. The problem was solved quite easily; I had to find this post*, where Mr. Boomer provided the right solution to another user, and that solution worked for me as well.

What kind of contract do you have with o2, and is it active?

I have a mobile phone contract (term contract) with O2. Yes, the contract is active and I use it.

Then log in using your phone number as your username.

Unfortunately, after I try to log in, I get this text: 

Die eingegebene Rufnummer/E-Mail-Adresse oder das Kennwort ist nicht korrekt. Bei mehreren falschen Versuchen wird der Login automatisch gesperrt. 

I don't know what could be the problem, I tried to log in from the computer, but it didn't help.

Hello ​@Liudmyla64 ,

welcome to our o2 Community 😀

What exactly is the error message you're getting?

Could you post an anonymised screenshot here? 

Kind regards,

Solveig

Hello ​@Liudmyla64 ,

Can you click on “Forgot password” and request a new password? 

Or you could try using a different browser. 

Kind regards, 

Solveig

You are not yet registered with this phone number!

I've been getting this error for a week, I used to go to O2 quietly, and a week ago I couldn't log in without obvious reasons. Unfortunately, I can't log in via SMS, and I can't log in via the contract number, because I reissued the contract and the data was not saved.

As I wrote, you are not registered with the contract. Use the link from my last comment.

I used your link to register, selected this item, but it redirects me back to the login tab, where I can't log in.

Have you tried the *Forgot Password* function?

Yes, the same problem persists, they ask me to enter my contract number, but unfortunately, I don't have it in printed and electronic form, so I recently reissued it.

When asked about the PKK, you still haven't verified your email address; otherwise, a different form of authentication would be requested. Wait until you have the four-digit code, then try again.
