Huawei secret code list.

Are you a Huawei user? If so, you might be intrigued to learn about some hidden tricks within your smartphone. This is especially useful if you want to troubleshoot any potential issues like a pro.

Huawei devices come with secret built-in codes and menus that can unlock some hidden features and diagnostic tests you never knew before. All you need to do is enter the Huawei secret code into the dialer to reveal this menu.

If you are curious, let us show you how these little tricks work.

Part 1. What Are Huawei Secret Codes?

Many Huawei smartphone users might not be aware of the existence of these Huawei secret codes. These codes essentially act as shortcuts to access hidden features or perform specific functions on their devices.

The types of information and settings accessible through these secret codes can vary, but they often include diagnostic tools, network information, and additional system configurations. For instance, dialing # #2846579 ## can enable the engineering mode code for Huawei so users can test hardware components and access advanced settings that are usually restricted in normal usage.

However, since these codes are primarily intended for debugging and engineering purposes, you should exercise caution when using them.

Part 2. Examples of Huawei Secret Codes and What Can They Do

To unlock the hidden features and access diagnostic tools on your Huawei device, you only need to enter specific codes into the dialer. These secret codes, though not widely advertised, can be used as a shortcut to access various settings and features.

Here are examples of Huawei's secret codes list and what they can do:

1. About Phone: ##0000##

Part 3. Why The Huawei Hidden Codes Didn’t Work

To use the Huawei hidden codes, you only need to dial the provided numbers. But if the Huawei secret codes didn’t work as expected, several factors could contribute to this issue:

1. Device Model Compatibility

These hidden features and diagnostic tests are available across various Huawei models. You can use it on a flagship model like the Huawei P40 Pro or a mid-range device like the Huawei Nova series. However, different Huawei models can vary in their compatibility with hidden codes. Certain codes may only apply to specific device models or series.

2. Regional Variations

Hidden codes might also vary depending on the region or country where the device was purchased. Codes that work in one region may not necessarily work in another.

3. Incorrect Input

Double-check the code and ensure it's entered correctly. Even a small error in inputting the code could result in it not working as intended.

4. System Restrictions

Some hidden codes may be disabled or restricted by default by Huawei to prevent unauthorized access or modifications to certain settings. In such cases, accessing these codes might require rooting or other advanced procedures, which could void warranties and risk damaging the device.

safe Downloadsafe & secure


The Huawei SIM lock code, also known as a PIN, serves as a security measure for the SIM card. Once activated, it prompts users to input the correct PIN whenever the device is powered on or switched to a new device, enhancing security by preventing unauthorized access.
If you know the password, enter it to unlock the SIM cards of your Huawei phone. If not, you can unlock the SIM with a PUK (pin unlock key) from your mobile provider. Try contacting your carrier and requesting the unlock code to get the Huawei network unlock code for free. Carriers usually have these codes or the capability to unlock the device remotely.
Activating Huawei’s SIM card lock can be a preventive measure against SIM phishing, a tactic that scammers employ to gain control of your phone's SIM card. These scammers collect personal information from various sources, such as social media and accounts using two-factor authentication. Then, they will deceive your carrier's customer service into transferring your number to a spare SIM card under their control.
