Hi @HvP_84 ,

have you checked your bill to check on the differences?

You can open your bill in the “Mein o2”-App and in the “Mein o2-Portal”. There you’d find an overview stating the costs and expanses.

Do notice something out of the line or unusual?

Viele Grüße,
Kurt

Hi..I check and seed the differences. 
Just this: 5 EUR monatl. Rabatt auf Ihre Grundgebühr - gültig bis 24.08.2021 is finish ! 

@HvP_84 

you started the contract in February 2021

The basic charge is 34,99 EUR/month

The router: 5,99 EUR/month

You got a discount of 24x10 EUR in the beginning of the contract and a 6 x 5 EUR on top. 

The 5 EUR discount was finished in August 2021 and that’s the reason for the new monthly price of 30,98 EUR.

Greetings
