What is SIM Swapping? Decoding the Meaning

SIM swapping or SIM hijacking is a type of cybercrime where your mobile number or SIM is targeted. Do you know how SIM swapping is done?

Scammers collect your personal details through phishing emails or social media and they contact your telecom operator and pretend to be you. They inform the telecom company that your phone was lost or damaged and request a new SIM. Then the new SIM is activated once the telecom operator approves the request. And now the scammers have full control of your messages and OTPs as your number is deactivated on your phone and activated on the fraudster’s SIM.

Now, your next question must be how to realise that my SIM has been swapped? The warning signs are:

• Your phone suddenly loses network connection or shows “No Service.”
• All of a sudden, incoming calls and messages cease coming to your phone.
• You start receiving alerts that your passwords are being reset.
• The mobile operator sends a message about the SIM change even though you did not initiate it.

Common Risks of SIM Swapping

Your phone is linked to your bank account, social media profiles, and also your Google accounts like Gmail. If you lose access to your SIM card, it will have serious consequences.

Commit Bank Fraud or Financial Fraud

If someone gains access to your phone, your OTP and verification messages can be viewed by them. These OTPs can be used to log in to your banking apps or even reset your passwords. After scammers change your password or login to your bank account, they can transfer money from your bank account to their account and even apply for a loan in your name and you will not even realise their actions.

Identity Theft

Once scammers take charge of your SIM, they can pretend to be you, that means they may ask your contacts to send money to your account, or even open fake accounts in your account. These acts can ruin your credit history and may land you in legal trouble.

Hacking of Social Media

Further damage can be caused if scammers hack your social media accounts and change your passwords to lock you out of your own accounts. They may also scam your friends and family online after gaining access to your account.

Loss of Privacy

Another major threat of SIM swapping is that scammers may view your private photos or messages and may misuse the data for blackmailing you, or if your account has sensitive data about your business or clients, it can be exposed and your professional life may be affected.

Damage to Reputation

The impact of SIM swapping is not just temporary. You may be affected for weeks or months trying to control all the damage you have faced. You may need to inform the bank and loan companies in case loan is issued in your name, and take care of social media accounts that have been hacked.

How to Prevent SIM Swapping

The first step to avoid SIM swapping is to understand how scammers initiate this type of scam. Fraudsters rely on weak security practices; so it is necessary you follow these security tips:

1. Never Share Personal Details Publicly

Fraudsters gather details about your date of birth, mobile number, address, and even your mother’s name from social media or websites. Using these details, fraudsters contact your mobile service provider.

So, do not post too much personal information on social media. Also, never share your personal information with unknown people.

2. Use Strong and Unique Passwords and Two-Factor Authentication (2FA)

This is a very common tip for all users in this digital world: provide strong and complex passwords for all your accounts so that scammers will not be able to access them.

Do you know the benefit of two-factor authentication (2FA)? It provides extra protection as it requires a second verification step to log into your account. You can also use authentication apps like Google Authenticator that make it difficult for scammers to intercept them even if they control your SIM.

4. Set a SIM Lock or PIN with Your Mobile Provider

Contact your mobile carrier and request additional security layers such as a SIM PIN or security password that must be verified before the SIM is replaced.

5. Beware of Phishing Scams

Scammers trick people through phishing scams and make them share confidential information; so beware of phishing scams. And never click on any suspicious links that will redirect you to fake websites.

6. Check Your Accounts

Keep checking your bank and social media accounts because if a scammer tries to access your account, you can immediately find it out and change the passwords. For your bank accounts, set up instant alerts. It helps to detect frauds in real-time.

7. Contact Your Mobile Carrier Immediately

If your phone suddenly displays “No Service” for a long period, contact your mobile service provider right away.
