I would say I have grown on some secret iPhone codes to find tools that Apple never displays. iPhone is quite famous for its security, mobility, and premium experience in the smartphone world. But are you aware that there are some secret codes and some hidden USSD codes that, when activated within your iPhone, instantly bring out some hidden features and diagnostics tools? Astonishingly, Apple has been rather cheap with general users with these codes; however, if you wanted, you could use them and expose much information inside the phone.

Uses of These Secret Codes on Apple iPhone:
You can verify by using these codes. To obtain signal strength in decibels (dBm), you will know exactly how far your phone is from the cell tower.
You may even get to launch the diagnostic menu for reporting purposes of the glitch.
You can check for call forwarding, call waiting, or even the IMEI number instantly.
Other network-specific information will be listed as well.
Such features are usually deep within settings or not displayed at all.
Some More Common iPhone Secret Codes
These common codes are generally safe for use in most Apple iPhone models:
*3001#12345#* — Use this one to enter the Field Test Mode. It displays the real signal strength in dBm.
*#06# — This instantly fetches your iPhone's IMEI number.
*#21# — Talks about whether call forwarding is either on or off.
*#67# — To check whether or not a call is being forwarded to another number when busy or when not answered.
*#31# — Caller ID check.
Using the codes is very simple: just open the phone app, type in the relevant code into the dialer, and press the call key to get the result.
Warning
All codes mainly serve meaningful purposes in verifying information as well as in accessing any type of network-related tools. On the other hand, codes that change the settings of the phone should be scrutinized before use. Any unknown codes should not be used; rather, consult your operator or an expert he/she is in doubt.

Conclusion
Be it ever so clever, some controls let iPhones down as they are never shown to an ordinary user. By the use of these codes, you will enjoy the privilege of being more informed about your phone, even as you get the information that you require immediately. These Hidden Codes should really make your iPhone experience smarter.
