Unwanted calls or text messages

Are you receiving threatening or insulting text messages? Are you being stalked or harassed on your mobile phone? Or do you regularly receive calls from an unknown number? Various actions can be taken, depending on the telephone number.

Do you often receive calls from an unknown or foreign number?

Does an unknown, often foreign number with a different country code than the Belgian +32, call you and do you hear a recording, static or nothing at all when you pick up? These are call centers that dial 10 numbers simultaneously: the first one to answer gets a salesperson on the line. The other nine numbers don't hear anything but will be called back later by the system. This is annoying, but often temporary.

  • Never call back an unknown number

    Never answer calls from numbers you don't know, especially international numbers (e.g. with country code +176, +88 or +372). Do not under any circumstances call back such numbers. They are often calls from fraudulent premium-rate numbers which charge excessively high rates, causing your bill to skyrocket.

  • Block the number on your mobile phone

    On most smartphones you can block contacts and known or unknown numbers. The guidelines for this are set out in your phone's user manual. Unfortunately neither we, nor the Telecom Ombudsman's Office can block these numbers for you.
