I cancelled my contract and O2 sent me an email asking to return the router and they gave me the serial number and the following link: https://router-retoure.o2online.de/app/dashboard

Unfortunately, the serial number is not found. My router is very old (2012). What should I do?

Good morning ​@router_return 🙂

Thank you for reaching out with your question.

We’re sorry to hear that you’ve canceled your service with us. Please use this link to request a router return and receive the shipping label. Let us know if that works out.

Thanks ​@o2_Kathi for your reply. Unfortunately, that link also doesn’t find the router. My router is an “o2 Box” from 2012. Its serial number is 2043008604. What should I do?

The o2 Box 6431 type is too old, the serial numbers are not available in the returns portal anymore. Please have the device disposed of properly (do not put it in the general household waste).

Hi ​@blablup. Thanks for the reply. So, just to be 100%, I will not get an invoice as per “Sollte der Router innerhalb der genannten Frist nicht bei uns eingehen, stellen wir Ihnen den entsprechenden Gerätewert in Rechnung.”?

@router_return blablup is right - the router is too old, which is probably why it no longer shows up in the returns portal. Are you sure the email we sent you is about returning this router? 🤔

yes, very sure. Here it is, you can see the same serial number.

Ok, so I just ignore this, ​@o2_Kathi ??

For a device that old the value would be 0 EUR.

@router_return 

you can ignore the message. No need to worry. There is no charge for non-return anymore.
