Google Fi has rolled out a new security feature called “Number Lock” aimed at preventing SIM swapping attacks, the company announced.
This feature enhances security by blocking the transfer of your phone number to a new device or porting it to another carrier without your explicit permission.
SIM swapping is a malicious technique where attackers fraudulently gain control of a victim’s phone number by convincing the telecom provider to transfer it to a SIM card under their control. This method is often used to bypass two-factor authentication (2FA) and gain unauthorized access to online accounts.
With Google Fi’s new “Number Lock” feature, users can proactively secure their phone numbers against such attacks. Once enabled, any attempt to transfer the number to a new device or port it to another carrier will require explicit authorization from the user. This adds an additional layer of protection against unauthorized SIM swaps.
Google Fi users are strongly encouraged to enable the “Number Lock” feature to safeguard their accounts and personal information. Given the potential severity of SIM swapping attacks, which can lead to unauthorized access and financial losses, proactive measures like this can significantly mitigate risks.
Setting up “Number Lock” on Google Fi is straightforward and can be managed through the account settings. By taking this precautionary step, users can ensure that their phone numbers remain secure and under their control, reducing the likelihood of falling victim to cybercriminal activities.
