Hi @siva123 

Welcome to our o2 Community. 

Could you please tell us which DSL contract you are using? You can find the name of your data plan / tariff on your monthly invoice/ bill,

then we can check why you got the email you quoted. 

Best Regards Matze 

I am using o2 my home S tariff

@siva123 really a my Home S and nota my Home S Plus?

@siva123  The o2 my home S has limited data volume of 100 GB. 

After 100 GB of traffic your DSL speed is limited to 2mbit till the next monthly bill cycle starts.

My contract started from 16.8.2020. Then the new billing cycle starts from ever month 16th. Am i right?

@siva123 That could be, but to be a 100% sure you can check you invoice / bill, there you find your bill cycle.

Here you can check and download you invoice.

I always get this error message when i try to login to find my invoice. What is the reason for it? what can i do to see my invoice

@siva123  Could you try it with a different browser, and if that wont work via our o2 App? 

There you should have full access to your customer data and your invoice.

You will have to sign in at home with your DSL connection and do the following steps:

Go to www.o2online.de  and afterwards “Jetzt registrieren” Put in your Personal Identification Code (PKK)  and klick “Registrierung”  Choose a username ( not your emailadress or landline number!!) and a password.
