1und1: How to post data volumes

First switch off the WiFi connection of your cell phone for the next steps.

1. Open the browser on your smartphone and enter the following URL:
2. //1und1.de/mobile-center
3. However, the corresponding website only opens when your WLAN is switched off. This is because this is about the mobile network and the WiFi would only interfere.
4. You will now be redirected to a page on which you can easily post the data volume.
5. But be careful: you can only book this after you have used up the majority of your inclusive data volume.
6. The newly booked data volume is not automatically added in the following month. So you have to book it again if you need it.
