How to know if they have cloned my mobile SIM card and avoid it

Something similar happens with the text messages. You see that you are not receiving SMS and you are sure that you should receive one, for example for the mobile access code. It is precisely the hackers’ goal to take control of these messages. In this way they will be able to control other accounts, such as social networks or the bank.

SMS today, although it may seem obsolete, is more important than ever. Think of a payment you make online and the code that comes to your mobile to verify it. The same when making a transfer, entering a social network from another computer, etc. It is what is known as two-step authentication and is basically a code that you receive by SMS. Hackers may aim to clone a SIM precisely to access those codes.

Internet connection gone

One more sign that there is something wrong with your SIM card is if you lose connection. You try to connect many times, you know you are in a coverage area but it doesn’t work. Basically it is as if you did not have the card inserted in the mobile. You do not receive a signal and you could not call, send messages or navigate.

However, losing your Internet connection can occur for many reasons. If this happens to you, it is better that you confirm it by sending SMS or receiving calls. The connection may have gone simply due to a specific problem with the line or a mobile failure for some reason that you do not control.

you have a different location

You might try looking at the phone location and it appears as if you were somewhere else. It is as if your mobile line were in another city or country. This can mean that your SIM card has been cloned without your knowledge and is certainly a red flag and something that will prompt you to take action to fix it.

It is common for someone who has cloned your SIM card to be somewhere else. A SIM Swapping attack impersonates your identity and someone else receives the card elsewhere as if it were really you. It would be very unlikely that the location of that person was the same as yours.

You get weird messages

Another reason for alert is when you start receiving strange messages. You may even see SMS from the attacker, where it tells you what you should do to solve a certain problem. That step is what could allow him to finally clone your mobile card and take control. However, if you receive SMS it means that the cloning has not been completed yet.

Yes, you could receive emails once your mobile card has been attacked. You could start receiving strange e-mails from the attacker or also from any other Internet service you are using.
