Social media is full of videos and blog posts claiming that you can secretly listen to another person’s phone calls simply by dialing a special code.

Some of these posts even claim that dialing codes such as:

• **06*PhoneNumber#
• *21
• ##002#
• Other so-called “secret GSM codes”

will allow you to hear another person’s conversations.

But are these claims actually true?

The short answer is No.

There is no legitimate GSM code, Android feature, or iPhone setting that allows someone to secretly monitor another person’s phone calls simply by dialing a code on their device.

In this guide, you’ll learn what these viral codes really do, why they don’t work for spying, how legitimate call forwarding works, and how to protect your own phone from unauthorized access.

Quick Answer

Can You Listen to Another Person’s Phone Calls Using a Secret Code?

No.

There is no official mobile network code that allows you to secretly receive or listen to another person’s calls simply by entering a few numbers on their phone.

Claims like these are internet myths.

If someone tells you that dialing a “magic code” will let you hear another person’s conversations, the information is false.

Why Are These Codes So Popular?

People search for topics like:

• How to listen to someone’s calls
• Secret code to spy on a phone
• Code to monitor my husband’s calls
• Code to listen to my wife’s phone
• Listen to girlfriend’s calls

because they are curious or concerned about trust in relationships.

Unfortunately, scammers and misleading websites often exploit these searches by promoting fake codes that do not work.

Their goal is usually to generate clicks, advertising revenue, or spread misinformation.

Does **06*PhoneNumber# Work?

No.

There is no recognized GSM feature that uses a code like **06*PhoneNumber# to forward or monitor another person’s calls.

If you see this code on social media, YouTube, Facebook, TikTok, WhatsApp, or another website, it is not an official feature supported by mobile network operators.

What Does *#06# Actually Do?

One code that is real is:

*#06#

This code displays your phone’s IMEI (International Mobile Equipment Identity) number.

Your IMEI is a unique identification number assigned to your mobile device.

It is commonly used for:

• Identifying a phone.
• Reporting a lost or stolen device.
• Blocking stolen phones from mobile networks.
• Warranty verification.

It does not:

• Listen to phone calls.
• Record conversations.
• Spy on another person’s phone.
• Forward someone else’s calls to your phone.

Can Someone Secretly Listen to My Phone Calls?

Modern smartphones include multiple security protections.

Without your knowledge or permission, another person generally cannot listen to your calls simply by entering a code on your phone.

However, unauthorized monitoring may occur in limited circumstances, such as:

• If malicious software (spyware) has been installed on the device.
• If someone gains physical access to your unlocked phone and changes settings.
• If your online accounts are compromised.
• If you voluntarily install software that grants call or microphone access.

Protecting your phone with a strong passcode, keeping your software updated, and only installing trusted apps can significantly reduce these risks.

Call Forwarding Explained, Legitimate GSM Codes, Phone Security, and Privacy Protection

Many people confuse call forwarding with call spying.

These are two completely different things.

Call forwarding is a legitimate mobile network feature that redirects incoming calls from one phone number to another under certain conditions. It is commonly used for convenience and business purposes—not for secretly listening to someone else’s conversations.

This section explains how call forwarding works, the GSM codes that are actually real, and how to protect your phone.

What Is Call Forwarding?

Call forwarding is a feature provided by mobile network operators that allows incoming calls to be redirected to another phone number.

People commonly use call forwarding when:

• Their phone is switched off.
• They are traveling.
• Their phone battery is dead.
• They are unavailable.
• They want calls answered by another device.

Call forwarding redirects incoming calls. It does not let someone secretly listen to your conversations.

Types of Call Forwarding

Most mobile networks support several types of call forwarding.

Unconditional Call Forwarding

All incoming calls are redirected immediately.

Call Forwarding When Busy

Calls are redirected only when you are already on another call.

Call Forwarding When Unanswered

Calls are redirected if you do not answer within a specified time.

Call Forwarding When Unreachable

Calls are redirected when your phone is switched off or has no network coverage.

Common GSM Codes That Actually Work

Unlike the fake “spy codes” shared online, the following GSM codes are widely supported on many networks (availability varies by carrier and device).

*#06#

Displays your phone’s IMEI number.

*#21#

Shows the status of unconditional call forwarding on many networks.

*#62#

Shows where calls may be forwarded when your phone cannot be reached.

*#61#

Shows forwarding settings when you do not answer incoming calls.

*#67#

Shows forwarding settings when your phone is busy.

##002#

Often clears call forwarding settings on many GSM networks.

Note: This code resets call forwarding settings. It does not remove spyware or stop illegal surveillance.

Network support may vary, so consult your mobile carrier if the code does not work.

How to Check Whether Call Forwarding Is Enabled

If you think your incoming calls are being forwarded, you can:

• Open your phone’s call settings.
• Look for Call Forwarding.
• Review each forwarding option.
• Contact your mobile network operator for assistance if you are unsure.

Modern Android and iPhone devices also allow you to manage call forwarding through the Phone settings or your carrier’s service.

Does Call Forwarding Allow Someone to Hear My Conversation?

No.

Call forwarding redirects incoming calls before they are answered.

It does not create a secret connection that lets another person silently listen to your conversations.

If someone else answers a forwarded call, they receive the call instead of you—they do not secretly join your active call.

Can Spy Apps Listen to Phone Calls?

Some commercial monitoring applications claim to provide call monitoring features, but these generally require:

• Physical access to the target device.
• Installation on the device.
• Appropriate permissions.
• In many places, the knowledge or consent of the device owner to comply with applicable laws.

Installing software on someone else’s phone without their permission may be illegal and violate their privacy.

Always respect local laws and obtain consent where required.

Signs Your Phone Security May Need Attention

While sensational “secret codes” are mostly myths, you should still pay attention to your phone’s security.

Consider reviewing your device if you notice:

• Unknown apps you did not install.
• Unusual permission requests.
• Unexpected changes to phone settings.
• Rapid battery drain caused by unfamiliar apps.
• Excessive mobile data usage without explanation.

These signs do not automatically mean your phone has spyware, but they are worth investigating.

How to Protect Your Smartphone

You can significantly improve your privacy by following these simple steps.

• Use a strong screen lock.
• Enable fingerprint or facial recognition where available.
• Keep your operating system updated.
• Install apps only from trusted app stores.
• Review app permissions regularly.
• Avoid clicking suspicious links.
• Enable two-factor authentication for important accounts.
• Keep your Google or Apple account secure.
• Do not leave your phone unlocked around people you do not trust.
• Back up your important data regularly.

Expert Advice

If you are worried about the privacy or security of your phone, focus on good security practices rather than internet myths.

Protect your own device with strong passwords, software updates, and careful management of app permissions.

Frequently Asked Questions, Phone Security Checklist, Privacy Tips, and Final Conclusion

This final section answers additional questions people ask about phone call monitoring, explains how to secure your smartphone, and summarizes the key points from this guide.

The goal is to help you separate facts from myths and protect your personal information.

Frequently Asked Questions (FAQs)

Can Someone Listen to My Phone Calls Without Me Knowing?

Under normal circumstances, no.

Modern Android and iPhone devices include multiple security features that make unauthorized call monitoring difficult.

However, if someone has physical access to your device or installs malicious software (spyware), your privacy could be at risk.

Always protect your phone with a strong passcode and keep your software updated.

Can Someone Spy on My Phone Just by Knowing My Number?

No.

Simply knowing your phone number is not enough for someone to access your phone calls, messages, or files.

Be cautious of online claims suggesting otherwise.

Does Dialing a Secret Code Install Spy Software?

No.

Entering a code into your phone’s dialer cannot secretly install spyware on modern smartphones.

Spyware, when it exists, is typically installed through malicious apps, phishing links, or physical access to the device.

Can Mobile Network Operators Listen to My Calls?

Telecommunication providers route phone calls through their networks, but they do not allow ordinary people to access or listen to another person’s calls.

Lawful interception, where permitted, is subject to legal processes and government authorization—not secret dial codes.

Can Someone Read My WhatsApp Messages Using a Secret Code?

No.

WhatsApp uses end-to-end encryption, meaning messages and calls are encrypted between participants.

There is no GSM code that unlocks another person’s WhatsApp conversations.

Can Someone Listen to WhatsApp Calls?

Not by using a dial code.

WhatsApp voice and video calls are encrypted, and there is no legitimate code that allows another person to silently join or monitor them.

Does Factory Reset Remove Spyware?

A factory reset can remove many types of malicious software because it erases the phone’s installed apps and data.

However, before resetting your phone:

• Back up important files.
• Remove your Google or Apple account if required.
• Follow the manufacturer’s instructions.

If you believe your phone has been compromised, you may also wish to seek assistance from your device manufacturer or a trusted repair professional.

How Can I Check My Phone for Spyware?

There is no single code that reveals spyware.

Instead, you can:

• Review installed applications.
• Remove apps you do not recognize.
• Check app permissions.
• Install updates.
• Run a reputable mobile security application if desired.

Can iPhones Be Hacked?

Although iPhones are designed with strong security features, no device is completely immune from security threats.

Keeping iOS updated and avoiding suspicious links greatly improves security.

Can Android Phones Be Hacked?

Yes.

Like any connected device, Android phones can be compromised if users install malicious apps or ignore security updates.

Downloading apps only from trusted sources significantly reduces this risk.

Which Is More Secure: Android or iPhone?

Both Android and iPhone offer strong security features when they are properly configured and kept up to date.

Your personal security habits are often more important than the operating system itself.
