Block calls and text messages on your mobile phone

If you have activated the pay-for option to block your calls, you can use the short codes below to block your calls and text messages to Belgian or international numbers. Blocking pay-for numbers (0900, voting, etc.) is always free of charge.
To block and unblock your calls and text messages via a short code, you need a secret code. This secret code is 0000 by default, but we advise you to change it as soon as possible so that you are the only person who can block and unblock your calls.

Changing your secret code

Type **03*330* Old code * New code * New code # on your mobile phone and press the call key. Instead of  Old code, enter your current secret code and instead of New code, enter a new 4-digit code of your choice.
