Hello @Sara184,
welcome to our o2 Community
The easiest way to cancel the speed options is online: Tarife & Optionen. If you klick on the corresponding details there, just go to “Abmelden” to cancel it by the next possible date.
Alternatively you can also cancel them in the Mein o2 App under “Vertrag” and “Alle Optionen verwalten”.
Please let us know if it was successful or if you have any further questions
Best regards
Giulia
ou can cancel the speed options in the customer portal, at tariff & SIM card under Internet and 5G options. Click on *Details* for the option you want to cancel and confirm the unsubscribe option.
