What is Phone Cloning?

A Girl Checking if her phone is being cloned.

Phone cloning is when a copy of a mobile phone is created. This means copying the phone’s ID number, IMEI number, and other SIM card details. Scammers can take important information from your device, like the SIM card details, receive OTP’s, make calls and texts by cloning your phone.

If your phone is cloned, the person can listen to your phone calls, read your text messages, and also access your financial account. This is like handing over your SIM card with all the information to a hacker.

This is why it is important to understand and recognize the initial signs of a cloned phone. You can protect yourself from being further damaged if you recognize and use preventive measures while using the device.

How can you tell if your Phone is cloned?

It is important to know and recognize the early signs of your phone being cloned or hacked, as it can prevent further damage.

One of the primary signs of your phone being cloned is that it performs unusual activity on its own. Not only this, but your device hints at different things, indicating that your phone is being cloned.

Here’s how you can tell if your phone is cloned:

Ways to tell if your phone is being cloned.

1. Unexpected data usage charge or billing

If someone cloned your phone, they could send messages, place calls, or access the Internet using your phone number. As a result, your data usage and bill may increase without your knowledge. This way, you will get high bills even if you used only the limited service.

Unexpected charges for data usage are one of the most common signs of a cloned phone. If someone is adding charges to your SIM card, they have probably duplicated it or hacked your phone.

2. Strange activity on your account

If you see suspicious activity on your accounts, such as unknown logins to your Google, bank, or social media accounts, it is possible your phone is hacked or cloned.

Hackers could be using your phone to log into your applications, change passwords, and obtain personal access. This can lead to the loss of money or identity theft.

If you are getting notifications or alerts about security, or you see unknown devices showing up with your accounts, then it is probably a hacker or a cloned SIM card accessing your personal information.

3. Increased Battery Drain

If your phone battery is dying quicker than usual, it is also one of the signs of a cloned phone. If someone cloned your phone, they can give permission for apps to be able to run in the background, which can listen to you or send codes to another phone without your knowledge.

This will use a lot of power. A hacked or duped clone of your phone would generally show a lot of activity like call monitoring or spying, which can cause the phone to heat up or run out more regular.

4. Receiving texts and messages meant for someone else

If you start getting strange text messages or spam that seem like mistakes or weren’t meant for you, that’s a big warning sign. It might mean someone has copied your SIM card and is using it on another phone.

When two phones have the same number, calls and texts go to both. You might see random messages, messages with suspicious links, OTP (one-time password), or verification codes that you didn’t ask for.

This often means someone is trying to use your phone number to access your accounts or trick your contacts into giving away personal information.

5. Poor device performance

If someone hacks or clones your phone, it may become very slow and struggle to perform simple tasks. You might see delays when opening apps, making calls, or sending messages. This happens because hacking software is running without you knowing, which lets the hacker spy on you.

If your phone starts having odd problems for no clear reason, it’s wise to check if it has been hacked or cloned.

6. Security alerts from services about logins from unknown devices

A key warning sign is if you get messages saying someone is trying to access your accounts from devices you don’t know. You might get unexpected codes or alerts from your Google account, bank apps, or social media.

This usually happens when someone is using a copied SIM card or phone to get your personal information. They might be trying to change your passwords or steal your sensitive data.

These messages mean someone is pretending to be you using a copy of your phone. If you get such a message, check if your phone has been hacked.

Code to check if phone is cloned

If you want to check whether your phone is cloned or not. You can check it by dialing *#06# on your phone. Here’s a step-by-step process with code to check if the phone is cloned.

Step 1: Open your phone’s dialer.

Step 2: Dial *#06#. As soon as you type in the code, your phone will automatically display a 15-digit number on the screen. This number is your IMEI (International Mobile Equipment Identity).

Step 3: Make sure to save it somewhere safe. You can also take a screenshot for reference.

Step 4: Check the original IMEI. Look at the IMEI printed on your phone’s box, or go to Settings > About Phone > Status > IMEI information to see the number saved in your device.

Step 5: Compare both numbers. If the IMEI shown with *#06# does not match the one on the box or in your settings, it could be a sign of IMEI spoofing.

How do People Clone Phones/ Ways

Hackers use different methods to spoof your phone and SIM card. If you are aware and attentive, you can prevent yourself from being a victim of a cloned phone.

Here is how hackers clone a phone:

1. SIM Card Cloning

SIM cloning refers to the process of creating an exact copy of your SIM card. Your SIM card is unique because it contains your mobile number and connects your phone to the mobile network.

A hacker can clone your SIM card using special pieces of equipment to copy the information from your SIM card to another SIM card and effectively create a cloned SIM.

When the cloned SIM connects to a network, it can receive your phone calls, send messages just like you would, and use your mobile data to be used. These things can lead to issues that may result in the theft of your online banking credentials, personal accounts on social media, and even other security and banking issues.

To prevent yourself from being a victim of SIM cloning, the best course of action is to protect your SIM card with a PIN and to be careful when sharing your phone.

2. IMEI Spoofing and Device Identity Theft

Another popular method is IMEI spoofing. Each cellphone has its unique IMEI (International Mobile Equipment Identity) assigned to it. This number is used to identify your phone on the network no matter its location.

A hacker can change the IMEI number of another phone so it appears to be yours, and the network will have no way of knowing. Once their phone has your IMEI number, they can listen to your calls, read your text messages, and get into your Google account or any other apps.

How to Protect Your Phone from Being Cloned?

You can safeguard your phone from being cloned through some security tips as well as smart device protection habits. You can protect your SIM card, your online accounts and your personal data from being stolen, by following some simple guidelines.

Here’s how you can protect your phone from being cloned:

A. Keep your software updated

Always ensure that your phone is updated to the most current version. Each update often eliminates security flaws that hackers leverage to copy a phone or hack your online accounts.

Many updates also cover software that blocks malicious links and unwanted apps that can steal your private information, including calls and texts.

B. Use strong passwords and PINs

Use a strong and unique password for all online accounts, like Google and social media, and set up a PIN for your phone’s lock screen. This protects your information from being accessed after a loss or theft, and keeps your SIM card safe.

C. Be cautious about public Wi-Fi

Use public Wi-Fi without an application less often. Hackers frequently take your information, send messages from your devices, or watch you when you are on open networks. If you use public Wi-Fi, use a VPN to keep your calls and data safe from spying and hacking.

D. Monitor your phone bill regularly

Look for strange charges on your bill, unexpected data use, or unknown numbers in your call log. These might mean your phone is hacked or that someone is using your number with a copied SIM card. The faster you report these changes, the quicker you can reduce the damage.

E. Be aware of phishing scams

Be careful when clicking on unknown links in texts or emails, or while receiving spam calls. Hackers use these to change your phone SIM card, take your login codes, and steal your online accounts and bank information.

F. Secure your voicemail with a PIN

If hackers get into your voicemail, they can listen to your private messages or even listen to calls while they happen, especially if you don’t use a PIN. Always choose a strong PIN for your voicemail to protect your calls and messages.

G. Be careful about sharing your IMEI or ESN number

Never put your IMEI number online or share it with people you don’t trust. It can be used to copy your phone and steal your identity, allowing others to intercept your calls and texts.

H. Enable SIM card lock

A SIM card lock is a security feature that asks for a PIN when someone tries to use your SIM card in another device. It helps stop hackers from copying your SIM and sending messages or making calls from your phone number.

I. Use a VPN on public networks

A VPN protects what you do online and keeps your accounts and social media safe when you use public Wi-Fi. It hides your connection so no one can steal your login information, watch what you do, or try to copy your phone from far away.

Conclusion

Phone cloning is a rising issue that is faced by a lot of people. With a few tricks and loopholes, hackers can spoof your phone and SIM card. By accessing your SIM card, they are able to listen to your calls, texts, and access your financial details.

Yet, you can stop this from happening by following proper precautions and by carfulness. You can check if your IMEI is correct or not by dialing *#06#, from which you can know whether your SIM card is cloned or not.

If you ever feel like your phone is being cloned, you are advised to take action quickly to protect and safeguard your data.
