Login in der o2 App nach Vertragsabschluss nicht möglich

Hello everyone,

I recently signed my contract digitally and provided my current email address. Unfortunately, I can't log in to the o2 app with it – the login fails. I'll send a screenshot of the error message shortly.

Additionally, the contract overview on the website isn't working either: When I try to access my contracts via the website, I'm repeatedly redirected to https://hilfe.o2online.de/. So it seems there's a technical problem.

Unfortunately, I can't get anywhere via the hotline either, as they always ask for the contract or phone number, which I don't have yet.

What can I do to be able to log in?

Thank you in advance!

Prepaid or postpaid?

It is a home internet tariff (Flex) with monthly cancelation and SEPA collection every month, so I assume it is postpaid

And is it active? If so, register the landline number and log in using the new login details. Currently, you are only logging in as an interested party, without any contract association.

The problem is I don’t have the landline number and not sure where to look for it. On my email I have received a link to track my order status, but when I click on it it forwards me on a blank page.

So the contract isn't active yet?

Yes, the activation should happen only on 20th according to the email. But the thing is - I want to have an access to the account so I can see the landline number so I can get through the hotline bot to talk to a person, because after 2 appointments with a technician which were scheduled by O2 - there is no possibility to have a cable internet in the apartment. So I wanted to switch over to DSL / Optic cable.

You can only register using the contract assignment option once the contract is active; it is not possible to do so before then.

Understood, then we’ll see on 20th of August. Thank you!
