Top 20 Hidden iPhone Secret Codes in 2023: iPhones contain unique codes that perform various functions unknown to the public.

There are specific codes for every smartphone that their manufacturer makes. It can be challenging to remember and use all of these codes effectively.
Everyone should know that this article shares some of the best and coolest iPhone secret codes.

The list of codes contains the top 20 hidden codes for iPhone for the year 2023: Finding information about the phone, hiding calls, or troubleshooting requires entering special codes into the dialer. So, let’s see some secret calling codes for iPhone.

Field Test Mode


This iPhone secret code provides the technical details of your network, such as signal strength in decibels. You can use it to see the code if you want to measure signal strength.

  • It would help if you had a smartphone connected to the internet first.
  • Access the phone software by entering a specific key sequence in the dialer.
  • Go to the LTE test menu by selecting it using the options listed in the field test menu.
  • Next, click the Render Cell Measurement button on the next screen.
  • Look next to the standard scale behind rsrp0 on the next screen.

The number after rsrp0 is the iPhone signal strength in decibels.

For those unfamiliar, the signal strength is pretty good if the number after rsrp0 is between -50dBm and -60dBm. Signal strength is good between -70dBm and -90dBm. Anything over 100dB means the signal strength is weak.

Test Mode in iOS 10 or Earlier


To enter field test mode on iOS 10 or earlier iPhone, you must follow a different path than iOS 10 users. You must open the Dialer app and enter the code before tapping the call button.

To check the signal strength, press and hold the Power button. If the Slide to turn off option doesn’t appear, don’t fire up until you get to the field test page.

To view the network strength in decibels, release the Home button instead of sliding. This will display the dBm rating in the upper right corner of the iPhone’s status bar.

Check the Call Forwarding Status


Call Forwarding allows you to divert incoming calls to another number. This is a great feature, and many people choose to turn it on, so they don’t wake anyone up during the night.

Under the iPhone dialer icon, a series of numbers and letters indicate the current call-forwarding status. Accessing this code requires entering an alphanumeric secret code via the iPhone dialer. After connecting, users can see the call forwarding status.

Divert Calls to Another Number


Well, this code is part of the USSD call forwarding code. If you want to forward calls to another number, you need to open your iPhone dialer, enter *21phonenumber#, and click on the call button.
