secret iphone settings

iPhones have a lot of different settings that the user can adjust to their liking. Most of these settings are clearly and easily available to the user, however iPhones have a bunch of secret codes that can be used to access hidden settings and information about the device. It works on any iPhone, is very simple to do and does not require a jailbreak or any kind of hack to use.

Some of these codes allow you to access settings, others give you information about your device and your SIM plan. There’s a lot of them to try, so you should have some fun testing them all out. To use them is pretty simple. All you have to do is open the Phone app on your iPhone and navigate to the keypad. From here all you need to do is enter one of the codes listed below and tap the call button! Don’t worry, it doesn’t actually make any calls or add any charges to your phone plan.

USSD Codes:

  • *3001#12345#* – Activate the Field Mode app. This contains all of your iPhone’s technical settings. It also converts the signal bars into an actual number.
  • *#5005*7672# – Check SMS center
  • *646# (Postpaid only) – Display your available minutes
  • *225# (Postpaid only) – Check your current bill’s balance
  • *#31# – Choose whether to hide your number
  • *3370# – Enable or disable EFR (Enhanced Full Rate), which improves your iPhone’s voice quality, but will quite likely reduce battery life
  • *#21# – Check call forwarding status
  • *777# (Prepaid only) – To check the account balance
  • *#62# – Check which number calls will be forwarded to if no service is available
  • *#76# – Check connecting line presentation
  • *#67# – Check the number to be used for call forwarding
  • *#33# – Check whether anything is barred, such as international calling etc.
