Your mobile phone number

Two phones, one number

  • 1 invoice and 1 call number, but 2 mobile phones and 2 identical SIM cards
  • Access to all Proximus services with 2 SIM cards
  • Stay connected at all times, even abroad

You'll  pay €25 to activate ProxiDuo and €6/month for using it.

Choose your number

  • Gold: choose a number that is easy to remember for everyone (for example: 047X 200 200) for the one-time fee of €198.
  • Silver: choose a combination of 6 digits free of charge. You can for example adapt your mobile phone number to match your landline (for example: 047X XX 87 93, if your landline is 02 xxx 87 93).
