How to Secure Your Phone Number
Keeping your phone number safe requires a mix of strong digital habits and practical steps. Here are key strategies to shield your number from hackers, scammers, and other threats:
Strengthen Your Account Security
Protect the accounts linked to your phone number by strengthening their security settings. Switch from SMS-based two-factor authentication to app-based authenticators like Google Authenticator for stronger protection.
Use strong, unique passwords for each important account, especially those related to banking, email, and social media. A good password manager can help generate and store these securely.
Keep Your Phone Number Private
Limit the exposure of your real phone number as much as possible. Avoid posting it publicly on social media profiles, forums, or unsecured websites.
If a website or service you don’t fully trust asks for your phone number, always opt for a temporary or disposable one to stay safe. Services like Google Voice, Burner, receive-sms.io, or specialized temporary SMS providers can help you register without risking your main number.
Be mindful what you share online in general. Scammers often gather publicly available information to impersonate you and trick you into giving away more sensitive data.
Use a Secondary or Virtual Number
Separate your online and offline identities by maintaining a secondary or virtual phone number. Use this secondary number when signing up for online services, newsletters, or promotional offers.
Reserve your real number for critical communications, like banking alerts, work contacts, and family. This division greatly reduces the risk of scams reaching your primary number.
Lock Your Mobile Carrier Account
Prevent SIM swap attacks by locking down your mobile carrier account. Set up a strong PIN or passcode that must be provided before making any changes to your account.
Ask your mobile provider about enabling extra security features like SIM lock or account freeze, if available. These steps can block unauthorized attempts to transfer your number to another SIM card.
Stay Alert for Red Flags
Stay vigilant for signs that your number may be under attack. A sudden, unexplained loss of mobile service could mean your SIM card has been cloned or swapped.
Watch for password reset notifications or account alerts you didn’t request — they can be early signs someone is trying to hijack your accounts.
Never interact with suspicious messages or unknown callers. If you receive a request for personal information, independently contact the company using official communication channels to verify it.
Avoid Phishing Traps
Scammers often try to trick you through links sent via SMS, messaging apps, or email. Avoid clicking on unknown links or giving out verification codes unless you’re absolutely sure who is asking.
Always verify unexpected requests by reaching out directly to the company or person through trusted contact methods.
Installing a mobile security app that includes phishing protection, such as Bitdefender Mobile Security with Scam Alert, can also help by warning you about malicious links in texts, notifications, and messages.
Secure Your Device
Keeping your phone itself secure is just as important.
Use a strong screen lock — whether it’s a PIN, password, fingerprint, or face recognition — to prevent unauthorized access if your phone is lost or stolen.
Consider adding an extra layer of protection with mobile security software that defends against malware, phishing attempts, and other threats.
What Can Scammers Do With Your Phone Number?
