The attacker may then receive your calls and text messages, including SMS verification codes. A sudden loss of service or an unexpected notice that your SIM was activated on another device can be a warning sign; contact your carrier immediately through a channel you know is genuine.
What is a SIM swap?
A SIM swap, sometimes called SIM swapping or a SIM takeover, is an unauthorized transfer of your phone number’s service to another SIM or device. If the carrier approves a fraudulent request, calls and texts intended for you may reach the attacker instead. That can expose SMS codes used to verify sign-ins or reset passwords.
A number takeover does not automatically reveal every password or give an attacker access to every account. Account compromise depends on whether the attacker can also obtain or use login credentials and account-recovery options. The Federal Trade Commission (FTC) explains how criminals may use a transferred number to receive verification texts and gain access to accounts that rely on them: FTC: SIM Swap Scams: How to Protect Yourself.
How do SIM-swapping attacks work?
- A criminal contacts your wireless provider and claims your phone is lost or damaged, or otherwise requests a transfer of your number.
- If the provider accepts the fraudulent request, it activates your number on a SIM or device the criminal controls. Your own phone may lose service.
- The criminal can receive calls and texts sent to your number, including SMS verification codes.
- If the criminal can also sign in with your credentials or use an account’s recovery process, they may access accounts, change passwords, or lock you out.
The risk is greatest for accounts that use your phone number for sign-in verification or password recovery. The FTC recommends using two-factor authentication, but notes that SMS codes can be vulnerable if someone takes control of your number: FTC: Use Two-Factor Authentication To Protect Your Accounts.

How can you tell if your number may have been SIM swapped?
- Your phone suddenly has no service. If you cannot make calls or send texts when you normally can, contact your carrier to find out whether your number or SIM was changed.
- You receive an unexpected SIM-change notice. A message saying your SIM was activated on another device may indicate an unauthorized transfer.
- Accounts show unfamiliar activity. Unexpected password-reset messages, sign-in alerts, changed account details, or missing access can indicate that an account was targeted, whether or not a SIM swap is confirmed.
A service outage can have other causes, so it is not proof of a SIM swap. To check, use your carrier’s known official app or website, or call a number you already trust. Do not rely on links or phone numbers in an unexpected message.
How to make a SIM swap and account takeover harder
Secure your carrier account
Set a PIN or password for your mobile carrier account. Ask the provider which additional account-change, SIM-transfer, or number-lock controls are available for your line. These protections can make an unauthorized change harder, but no PIN or carrier control is a guarantee against fraud. The FTC describes a carrier-account PIN or password as a measure that could help protect your account.

Limit information that can help someone impersonate you
Avoid sharing sensitive personal information in response to unsolicited calls, texts, or emails. If a message claims to be from a company, contact it using a channel you already know is genuine. Where practical, limit public exposure of personal details such as your full name, address, and phone number; an identity thief may use such details when trying to answer security questions.
Use a stronger second factor than SMS when available
For important accounts, prefer an authenticator app or a hardware security key over text-message verification when the service supports it. Authenticator apps generate codes on a device rather than sending them to your phone number; some also support sign-in approval notifications. A physical key can provide a strong second factor, but the account must support it and the key must be compatible with your devices.

The FTC calls security keys the strongest method of two-factor authentication among the methods it discusses because they do not use credentials hackers can steal. A key protects sign-ins for compatible accounts; it does not prevent a carrier from transferring your phone number. Check account and device compatibility before choosing one. See the FTC’s guidance on two-factor authentication options.
Use unique passwords
Give each important account its own password. If a password is exposed or reused, criminals may try it on other services. A unique password limits the damage one compromised login can cause.

Which authentication method is more resistant to a SIM swap?
| Method | What happens during sign-in | Resistance to number takeover | What to check |
|---|---|---|---|
| SMS code | A service sends a code to your phone number. | Vulnerable if an attacker takes control of your number. It is better than no second factor when it is the only option. | Use a stronger option if the account offers one. |
| Authenticator app | An app generates a code on a phone or tablet; some apps can send sign-in approval notifications. | Not susceptible to a SIM swap in the same way as SMS codes. | Confirm the service supports the app and keep access to it available. |
| Physical security key | You use a hardware key as a second factor; models may connect through USB or NFC. | More resistant to number takeover because sign-in does not depend on receiving an SMS code. | Confirm that both the account and your device support the key and its connection method. |
Not every service offers every method. If SMS is the only available second factor, it can still be preferable to having no second factor; protect the carrier account and move to an app or key if the service adds that option.
What to do if you suspect a SIM swap
- Contact your carrier immediately. Use its known official app, website, or phone number. Tell the provider you suspect an unauthorized SIM change, ask to regain control of your number, and secure the carrier account.
- Secure your email and financial accounts. Once you can access your number and accounts, change passwords, starting with email and financial services. Use new, unique passwords rather than reusing any password that may have been exposed.
- Check financial activity. Review bank, credit-card, and other financial accounts for unauthorized charges or changes. Report suspicious activity to the relevant institution.
- Review sign-in and recovery settings. On important accounts, check recovery phone numbers and email addresses, recent sign-ins, and other account changes. Replace SMS recovery with an authenticator app or security key where available.
- Get identity-theft recovery guidance if sensitive details were exposed. If Social Security, bank, credit-card, or other sensitive identity information may have been compromised, use IdentityTheft.gov for steps suited to your situation.
What U.S. rules say about carrier protections
The Federal Communications Commission (FCC) adopted an order on November 15, 2023, titled Protecting Consumers from SIM Swap and Port-Out Fraud (FCC 23-95). The order describes baseline measures for wireless providers, including secure customer authentication before SIM changes, notices about changes, options for customers to lock accounts against SIM changes, and safeguards related to employee access to customer information.
