To which operator does the number belong that I am calling?

You can identify the operator of a number by means of two options:

  • Via Offnet beep: You will hear a beep when the person you are calling is not part of the BASE network. Enter *555*# and press the call button in order to activate or deactivate the service.
  • On www.1299.be: enter the number to find out to which operator this number is linked.
