SIM swap fraud occurs when scammers take advantage of a weakness in two-factor authentication and verification and use your phone number to access your accounts. SIM swapping happens when scammers contact your mobile phone's carrier and trick them into activating a SIM card that the fraudsters have.
To perform a SIM card hacking through a SIM card swap, a hacker will first call up your phone provider. They'll pretend to be you and ask for a replacement SIM card. They'll say they want to upgrade to a new device and, therefore, need a new SIM. If they are successful, the phone provider will send them the SIM.
No Account Access
In some cases, getting locked out of other accounts that have two-factor authentication set up is also a sign of a compromised SIM card. Once the scammers move the number to their device, they'll receive the authentication text messages instead of you.
Sim Card Hacking, also known as a SIM Swap Attack, SIM Port Hacking, or SIM Hijacking, occurs when a hacker persuades your cell phone carrier to move your cell phone number over to their device instead of yours. This causes any calls or texts to go to the hacker's device instead of your own.
Mysterious apps, calls, or texts appear: A potential telltale sign that your phone has been hacked is the appearance of new apps that you didn't download, along with spikes in data usage that you can't account for. Likewise, if you see calls in your phone's call log that you didn't make, that's a warning as well.
More than 2,000 complaints of SIM swap fraud were reported to the FBI in 2022, up from more than 1,600 complaints in 2021 and only 320 from 2018 to 2020. The losses in 2022 total more than $72 million, more than $68 million in 2021, and around $12 million from 2018 to 2020.
SIM Cloning in basically creating a duplicate SIM from the original one. It is similar to SIM swapping. However this is a technically sophisticated technique, where software is used to copy the real SIM card.
If I put my SIM card in another phone, will my number be the same? If you insert your SIM card in a new phone, your phone number will stay the same. A SIM card is only associated with one phone number at a time, so it won't change even when you insert it into another phone.
In theory, once the carrier adds the IMEI to the blocklist, the smartphone will not be able to connect to the mobile network even with a different SIM card.
Theft and unauthorised access to personal information are common problems that can have serious financial and emotional consequences on individuals. Therefore, it is important that individuals take proactive measures to protect their devices, and one such measure is to enable SIM locks.
SIM swapping, also known as SIM splitting, simjacking, or SIM hijacking, is a technique used by fraudsters to get control of your phone number. With your phone number, hackers can take advantage of two-factor authentication to gain access to your bank accounts, social media accounts, and more.

SIM Card Tracking
Even a dumb phone (i.e. not a smartphone) can track you through the SIM card. SIM cards connect to nearby signal towers for you to receive calls and send SMS texts, but that signal can be used to find out your location.
Go to Find My Device if you have an Android device linked to your Google account and check the location. Apple, Samsung, and other OEMs have their own versions of phone-finding apps, and there are some excellent third-party options as well. If you see a second location on these apps, someone has cloned your phone.
Card cloning and SIM duplication
Once the phone provider is convinced, they transfer the victim's phone number to the new SIM card. It is done by deactivating the original SIM card and activating the new one in a mobile phone in the hands of the scammer.
At its most basic level, the main Simjacker attack is sending an SMS to a mobile phone with a special sort of spyware-like malware, which tells the UICC (SIM Card) within the phone to take over the phone in order to receive and conduct sensitive orders.
SIM swapping, sometimes called a SIM hijacking attack, occurs when the device tied to a customer's phone number is fraudulently manipulated. Fraudsters usually employ SIM swapping as a way to receive one-time security codes from banks, cryptocurrency exchanges, and other financial institutions.
To avoid succumbing to a SIM jacking, it is crucial that phone users take steps to protect their devices. From implementing security measures with their phone company and limiting how many personal accounts are associated with their number, each can prove useful to prevent a SIM swapping attack.
Is SIM Swapping Illegal? Yes, and customers can file a SIM swap lawsuit to recover money damages.
