Dear Telekom customers,
Use your fixed line number on the go. With One Number it is possible to signalize the fixed line number when calling somebody from the mobile phone. The app allows you to switch this feature on and off. With thanks to the list of exceptions it is easy to select contacts which still will see the mobile number.
Have fun with the app!
Your One Number team
