It is highly unlikely for a virus to infect a SIM card as SIM cards do not contain executable files that can be infected with viruses. However, SIM cards can store data such as contact numbers, SMS, and other personal information that can be compromised by malicious software or apps on a mobile phone.
In that case, the answer is an unqualified "absolutely." In short, though, SIM cards aren't just little memory cards. They are very tiny self-contained computers. They can, themselves, run malware.
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.
