Phone hacking poses a serious threat to privacy and security. Many users want to know if their devices have been compromised. Dialing certain codes can help check if a phone has been hacked or tapped.
These special codes, known as MMI (Man-Machine Interface) codes, allow users to access hidden menus and information on their phones. By entering specific sequences, individuals can detect potential security breaches. For example, dialing *#21# reveals if call forwarding has been set up without the owner’s knowledge.
Regularly checking for signs of hacking is crucial in today’s digital landscape. While these codes provide valuable insights, they should be used in conjunction with other security measures like updating software and using strong passwords.
Understanding Phone Security Checks
Common Dial Codes and What They Mean
Several dial codes have been shared online as ways to check for phone forwarding or other activity that might suggest your phone is compromised. It’s important to know these codes give limited information. They mainly show call forwarding settings, not direct evidence of hacking. Here are some of the most common codes:
- *#21#: This code shows if calls, SMS messages, or data are being diverted.
- *#62#: This checks if calls are forwarded when you’re unreachable (e.g., phone is off or has no signal).
- ##002#: This code cancels all call forwarding.
- *#06#: This displays your phone’s IMEI (International Mobile Equipment Identity) number, a unique identifier for your device. This is useful for reporting a lost or stolen phone, but it does not directly indicate if your phone has been hacked.
These codes interact with your carrier’s systems, showing the settings they have on file for your number. They don’t scan your phone for malware or other signs of intrusion. Think of it like checking your bank statement; it shows the transactions recorded by the bank, not hidden cash in your house.
What These Codes Can and Can’t Tell You
These codes offer a quick way to check your call forwarding status. They are helpful for confirming if forwarding has been set up, either by you or without your knowledge. However, they do not detect sophisticated hacking techniques, such as spyware or remote access tools, that operate outside of standard call forwarding. Modern malware can operate in the background and not affect call forwarding settings. If you suspect your phone is compromised, these codes are not sufficient on their own.
Alternative Methods for Checking Phone Security
If you’re worried about your phone’s security, consider these steps:
- Check App Permissions: Review the permissions granted to the apps on your phone. Look for apps with unnecessary access to your contacts, microphone, camera, or location. On Android, go to Settings > Apps. On iOS, go to Settings > Privacy & Security.
- Update Your Operating System: Keep your phone’s operating system (Android or iOS) up to date. Updates often include security patches that fix known vulnerabilities.
- Use a Mobile Security App: Consider installing a reputable mobile security app that can scan for malware and other threats. Many providers offer free and paid options.
- Be Cautious of Phishing: Be wary of suspicious emails, text messages, or links that could lead to malware or phishing websites designed to steal your information.
Recommended Security Apps and Software
Several reputable apps and software can help you scan for malware, viruses, spyware, and other threats on your phone:
- Malwarebytes: Known for its desktop anti-malware software, Malwarebytes also offers a mobile version that scans for malware and other threats.

Understanding Code *#21# and Call Forwarding
The code *#21# is a USSD (Unstructured Supplementary Service Data) code used on GSM (Global System for Mobile Communications) networks. It’s a quick way to check the status of various call forwarding options on your phone. When you dial *#21# and press the call button, your phone sends a request to your mobile network operator. The network then responds with information about whether call forwarding is active for different services.
Here’s a breakdown of what *#21# checks for:
- Call Forwarding Unconditional: This means all calls are forwarded to another number immediately, regardless of whether your phone is busy, unanswered, or unreachable.
- Call Forwarding When Busy: This forwards calls only when you’re already on another call.
- Call Forwarding When No Reply: This forwards calls if you don’t answer within a certain timeframe.
- Call Forwarding When Unreachable: This forwards calls when your phone is turned off, has no signal, or is in airplane mode.
- Forwarding for Data, SMS, and other services: The code may also show forwarding status for data, SMS messages, and other services offered by your carrier.
The response you receive after dialing *#21# will typically show one of two things for each service:
- Voice Call Forwarding: Forwarded to [Number]: This indicates that calls are being forwarded to the specified number.
- Voice Call Forwarding: Not Forwarded: This means call forwarding is not active for that particular service.
Important Considerations:
- Not a Hack Detector: It’s crucial to understand that *#21# only checks call forwarding settings. It does not detect malware, spyware, or other forms of phone hacking that operate outside of standard call forwarding.
- Carrier Specifics: The exact output and functionality of *#21# might vary slightly depending on your mobile network operator.
- Privacy Implications: If you find that your calls are being forwarded to a number you don’t recognize, it’s a reason for concern. It could indicate unauthorized access to your phone or account. In such cases, contact your mobile carrier immediately.
- Cancelling Forwarding: To cancel all call forwarding, you can usually dial ##002#.
In short, *#21# is a useful tool for managing and checking your call forwarding settings, but it should not be relied upon as a primary method for detecting phone hacks.
Factory Resetting Your Phone
A factory reset erases all data and settings on your phone, returning it to its original factory state. This can be a drastic step, but it can be effective in removing persistent malware or resolving other software issues. Make sure to back up important data before performing a factory reset, as this process will erase everything on your device.
Factory Resetting an Android Phone
- Open your phone’s Settings app.
- Tap System (or General Management on some Samsung phones).
- Tap Reset options.
- Tap Erase all data (factory reset).
- Confirm your choice and enter your PIN or password if prompted.
Factory Resetting an iPhone
- Open the Settings app.
- Tap General.
- Tap Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- Enter your passcode or Apple ID password if prompted.
What About Airplane Mode?
There is a common misconception that putting your phone in airplane mode stops all tracking. While airplane mode shuts off cellular, Wi-Fi, and Bluetooth connections, it doesn’t prevent tracking if malware is already installed on your device and has found ways to exfiltrate data when you turn airplane mode off. It’s best to rely on multiple layers of security, not just airplane mode.
Staying safe online requires a multi-faceted approach. While dial codes can offer a quick overview of call forwarding settings, they should not be the only security measure you use. Combining these checks with strong passwords, software updates, cautious app management, using reputable security apps, and awareness of phishing attempts provides much stronger protection against modern threats. If you suspect a serious compromise, a factory reset might be the most effective solution, but remember to back up your data first.

Understanding Phone Security
The text highlights concerns about phone security and the misconception that simple dial codes, such as *#21# or ##002#, can detect hacking. These codes only reveal call forwarding settings, not evidence of malware. To protect your phone effectively, a multi-layered approach is necessary, which includes basic checks, stronger security practices, and possibly performing a factory reset to restore the device to its original state.
Phone security involves protecting mobile devices from unauthorized access and malicious attacks. It encompasses various measures to safeguard personal data and prevent hacking attempts.
The Role of IMEI in Mobile Security
The International Mobile Equipment Identity (IMEI) is a unique 15-digit code assigned to every mobile device. This number plays a crucial role in phone security. Network operators use IMEI to identify and track devices on their networks. If a phone is stolen, the owner can report the IMEI to their carrier, who can then block the device from accessing the network.
IMEI also helps in preventing phone cloning. Cloning involves copying a phone’s identity to another device. With unique IMEI numbers, this becomes much harder. Users can check their IMEI by dialing *#06# on most phones.
Common Techniques of Phone Hacking
Phone hacking methods have evolved significantly. Spyware is a common tool used by hackers to gain unauthorized access to devices. This malicious software can be installed through seemingly harmless apps or links.
Phishing attacks trick users into revealing sensitive information. Hackers often send fake emails or text messages that appear to be from legitimate sources. These messages may contain links that install malware when clicked.
Phone tapping, another hacking technique, involves intercepting phone calls or messages. This can be done through various methods, including exploiting vulnerabilities in cellular networks.
Tracking apps, while sometimes used legitimately, can also be tools for hacking. These apps can monitor a phone’s location and activity without the user’s knowledge.
Proactive Measures and Detection
Detecting phone hacking requires vigilance and knowledge of specific indicators. Regular checks and understanding unusual behaviors can help identify potential security breaches.
Using USSD Codes to Check Call Forwarding Status
USSD codes provide a quick way to check if calls are being forwarded without your knowledge. To check unconditional call forwarding, dial *#21#. For conditional call forwarding, use *#62# for no answer, *#67# for busy, and *#61# for unavailable.
These codes display the status of call forwarding on your device. If any forwarding is active and you didn’t set it up, it could indicate unauthorized access.
• *#21# – Check all call forwarding
• *#62# – Check call forwarding when unreachable
• *#67# – Check call forwarding when busy
• *#61# – Check call forwarding when unanswered
Assessing Unusual Phone Behavior
Unusual phone behavior can signal potential hacking. Watch for unexplained data usage spikes, which may indicate background data transmission to unauthorized parties. Sudden battery drain can result from malware running constantly.
Other signs include:
- Strange text messages or emails sent from your account
- New apps appearing that you didn’t install
- Phone running hot or slow for no apparent reason
- Difficulty shutting down the device
Keep track of your phone’s normal behavior to spot these anomalies quickly.
Steps to Take if You Suspect Your Phone is Hacked
If you suspect your phone is hacked, act quickly to minimize damage. First, change all your passwords, especially for sensitive accounts like email and banking. Use strong, unique passwords for each account.
Next, remove any suspicious apps and update your software. Both Android and iOS have built-in malware scanners – use them.
Consider a factory reset if problems persist. This erases all data, so back up important information first. After the reset, restore only from a known clean backup.
Lastly, enable two-factor authentication on all accounts that offer it. This adds an extra layer of security, making it harder for hackers to gain access even if they have your password.
