At its most basic level, during a SIM swap, a SIM hijacker convinces your mobile carrier to port your phone number over to their SIM card. By transferring those incoming messages, fraudsters can easily access your most sensitive accounts by completing text-based two-factor authentication checks.
In 2021, the FBI received 1,611 SIM-swapping complaints, up from 320 complaints in the three years prior. I've been with PCMag since October 2017, covering a wide range of topics, including consumer electronics, cybersecurity, social media, networking, and gaming.
Although the SIM PIN does not prevent SIM swapping attacks, it adds a layer of physical security if the device is lost or stolen by protecting it from others activating the SIM card on another mobile device for phone calls and cellular data.
Cloning. This is the process of duplicating another phone's SIM card in order to gain access to that person's account information and services. Sim cloning occurs when a hacker connects two devices together using special software and hardware.
SIM swapping, also known as SIM splitting, simjacking, or SIM hijacking, is a technique used by fraudsters to get control of your phone number.
In many cases, SIM numbers are changed directly by telecom company employees bribed by criminals. Once this happens, the victim's phone will lose connection to the network, and the fraudster will receive all the SMS and voice calls intended for the victim.
Yes, you should be able to remove a hacker by doing a factory reset on your phone. Keep in mind that this solution will remove all of your data, including contacts, third-party apps, photos, and other files. You will need to set up your phone entirely from scratch.
A replacement SIM lets you move your number to a new SIM if your old SIM is lost, stolen or damaged, or if you need a different size SIM for your new device. A replacement SIM can take up to 24 hours to activate in busy periods, however it's usually much quicker.
One of the very first signs of SIM hacking that you'll notice is a seemingly random text purporting to be from your network provider asking you to restart your device. This is usually a message sent from the hacker. Restarting the phone gives them a chance, whilst the phone is off, to steal your SIM details.
Use a people search site/people finder tool
Simply enter the person's name, and you should be able to find any additional numbers associated with that individual. True People Search is a free website that allows you to search by name or phone number. If a second number is listed, it will appear in the results.
Using the Simcard you want to verify, dial *400#. Wait for some few seconds for the result to load. If registered properly, you will see your name in full.
No. SIM cards do not store data.
Your mobile phone may detect that another device is using the SIM card assigned to it. Some phones require users to restart the phone when this happens. When the restarting process is complete, you won't be able to make calls or send texts.
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.
Reduced battery life is one of the first signs that your phone has been hacked. Malicious apps that run in the background will drain your battery more quickly than usual. Your bill shows higher than expected data usage. Hacked devices will often use more data than you typically use.
Monitor the applications running in the background of your device and check whether there are any unknown applications. Notice significant increases in device temperature and decreases in battery life. These often indicate your Android device is being accessed remotely.
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.

Let your mobile carrier know right away if you think that your phone number may be hacked or compromised. Your provider can help you regain access to your phone or hacked SIM card, if that's the case. Most major carriers also offer spam and scam call blocking tools to reduce the amount of scam calls that you receive.
Is SIM Swapping Illegal? Yes, and customers can file a SIM swap lawsuit to recover money damages.
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.
If someone else has control of your phone number, calls and SMSes may be diverted to their cloned device, or your cellular connection stopped entirely. Check this by having a friend or your partner call you to see if the call rings and if it comes through to your phone.
