Here are six “hidden” codes that are worth checking out.

The video above comes from our colleagues at Business Insider. They’re all pretty straightforward to activate – simply dial the digits and symbols as instructed and you should be good to go. (You can turn most of them off again by dialling the same number.)

#31# – Block caller ID
*3001#12345#* – Field Test Mode
*#06# – Shows unique code identifier
*33*PIN# – Enable call barring
