Just like Android phones, iPhones also have secret codes that can show you hidden stuff like how strong your signal is, to secret testing menus. Instead of digging through tons of settings, you can just put in a few numbers and symbols to see what’s going on under the hood. Let’s check out all iPhone secret codes that are tested and are working.

What are iPhone Secret/Hidden Codes?
These iPhone secret/hidden codes are a combination of numbers, asterisks (*), and sometimes the hash sign (#) you type into your iPhone’s Phone app, just like you’re making a call. But instead of calling someone, these codes unlock hidden menus or show you different iPhone-related information.
Some codes can show you details about your network connection, others can let you test different hardware parts of your phone, and some even unlock special settings. While they might not be as widely known as regular settings, these hidden codes can be super handy for troubleshooting, checking device info, or just geeking out about your iPhone’s capabilities. There are different kinds of these codes, and we’ll explore what they can do.

There are two types of secret codes. Let’s take a look at them one by one.
- MMI (Man-Machine Interface Codes). These codes have been designed by your phone’s manufacturer. It can help you access hidden settings and even enable disabled features. But since these are brand-specific, a code compatible with OnePlus phones may not work with Samsung ones.
- USSD (Unstructured Supplementary Service Data): USSD codes can be entered via the dialer of your phone and are useful for getting carrier-related info. For example, if you wish to get details about your remaining balance, talk time, bills, or additional charges, these are the codes to use. You can easily identify a USSD code since it begins with an asterisk and ends with a hash.
How to Use Secret Codes on iPhone?
Using these secret codes on an iPhone is pretty straightforward. You just need to follow these steps:
- Open the dialer app on your iPhone that you use to make phone calls.
- Tap on the keypad option where you can dial phone numbers.
- Enter the secret code, including all the asterisks (*) and symbols. You can copy and paste the code to prevent any mistakes.
Note: While most codes require pressing the ‘Call’ button to execute, some, like the IMEI display code (*#06#), activate instantly upon typing the final # symbol.
A Word of Caution: Using some of these codes can be risky since they directly let you tinker with the hardware.

Universal vs. Carrier-Specific Codes
iPhone dialer codes fall into two main categories:
Carrier-Specific Codes: Many codes, particularly those related to account balance inquiries, data usage checks, or management of carrier-specific network features (like T-Mobile’s Binge On or Scam Block), are unique to each network operator (AT&T, Verizon, T-Mobile, etc.). These codes will only function when the iPhone is connected to that specific carrier’s network.
Universal Codes: These are designed to function irrespective of the mobile carrier. A prime example is *#06# for displaying the IMEI, which is a standardized code across the mobile industry. Other codes related to fundamental GSM/UMTS/LTE features (like basic call waiting or forwarding checks) often fall into this category.
