The advance payment is only for the phone order. If you don't want the mobile contract either you will need to cancel it within 14 days of receiving the contract confirmation by sending an email to widerruf@cc.o2online.de. You can then order a phone (and mobile contract) again. You don't need to return the SIM, just make sure you don't use it.

Thanks for your help and answer.

I'm sending an email to this address and I hope I get some quick feedback.

Hi @Maxcimus, 

welcome to our English Community. 

I regret that something went wrong with the payment of your device so that you had to cancel everything. 

The device will be cancelled automatically and the suggestion of bS0 is correct for your tariff. You will get a confirmation of the cancellation by e-mail. 

If you are still in the 14 days-withdrawal-period, you will not be charged or the charges will be returned back to you. 

Would you like to order phone and sim-card again?

Loving greetings,

Tobias

Hi.

I'm glad you helped quickly. My e-mail was returned the same day and I received a cancellation confirmation.
Yes I will renew my order now :)
Thank you for your help.

Hi @Maxcimus, 

great that everything is clarified now. 

We look forward to welcome you as a new o2 customer soon. 

In the mean-time, have a look to the different areas of our Community. 

By the way, do you know that we also have an English-speaking hotline? Just have a look here: 

Loving greetings,

Hi 

I ordered again, but I can't get information about my order. It gives an error when I enter the required information My new phone should arrive fast. I need it for my job. Please help me get information. When will my new phone arrive?

@Maxcimus 

you answered the email with the payment link to confirm your bank details?

Greetings

Yes i did it at 29Oct.

Okay, thank you for your reply.

Your phone is in state of waiting to be shipped. Unfortunately we have no binding date when it will be.

Greetings
