Unlock Extra iPhone Features With These ‘Secret’ Codes

Your iPhone’s number pad is chiefly designed for making phone calls. However, it can also be used to input a handful of special codes that unlock extra features. Some are useful for everybody – such as showing exact signal strength – while others are handy for specific types of users – like displaying your call forwarding status. 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.)

Here are a few highlights:

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

Our favourite has got to be the code that shows a more accurate reading of signal strength – handy for those patchy train commutes. To see the full range of codes, click on the video above!
