Signs that your SIM card has been cloned

Hackers could clone your SIM card without you noticing.

To do this, they can use social engineering and impersonate their identity. This is a serious problem as they could act on your behalf, receive 2FA codes to log into their accounts, make calls or send text messages, etc. There are some red flags that may indicate that your mobile card has been cloned or, at least, that there is something strange.

This type of attack is known as SIM card swapping. Basically, it is a cybercriminal capable of cloning your mobile card. You will always use a strategy to achieve this, either by deceiving the phone company or the user himself. Fortunately, this is not a common problem, as there are important security measures in place. However, it is convenient to know what signs there may be and thus avoid problems.
