What to do if…
you lose access to your financial accounts because your phone number was hijacked or SIM swapped

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Use official routes to contact both your bank or card issuer and your wireless carrier as the first urgent actions. Ask the bank to restrict risky account activity, and ask the carrier to secure the number and investigate the SIM swap or port-out.

Do not do these things

  • Do not keep trying password resets after one or two failed attempts; use the bank’s official support route instead.
  • Do not trust incoming calls, texts, or emails claiming to be your bank, carrier, or payment app.
  • Do not share or approve any code, prompt, password reset, or account-change message you did not start.
  • Do not treat control of the phone number as proof that an account is safe until the carrier confirms the wireless account is secured.
  • Do not focus on explaining exactly how it happened before you have asked the bank to restrict risky transfers.

What to do now

  1. Contact your bank or card issuer using an official route. Use the number on the back of your card, the bank’s official app, or the bank’s official website. Say: “I may have lost control of my phone number through SIM swap or port-out fraud. I am locked out and need urgent account-takeover help.”

  2. Ask what they can pause, block, or review right now. Ask them to check recent logins, password resets, payee changes, address changes, cards, checks, ACH transfers, wires, and peer-to-peer transfers. Ask what can be temporarily restricted while identity is verified.

  3. Ask them not to rely on SMS while the number is unsafe. Ask for non-SMS recovery only if the bank says it is safe, such as secure in-app support, branch identity check, or another verified route. Ask them to add a note that the phone number may be compromised.

  4. Secure payment apps connected to that number. From a trusted device, contact support or use the official app to lock or limit transfers if available. Check for new devices, changed email addresses, changed phone numbers, new bank links, or recent payments.

  5. Contact your wireless carrier’s fraud or security team. Say you suspect SIM swap or port-out fraud. Ask them to investigate, restore control of your number where possible, remove unauthorized devices or account changes, add a strong account PIN or passcode, and turn on any transfer lock, number lock, or port-out protection they offer.

  6. Ask the carrier for incident documentation. Ask for written confirmation or a case number showing suspected SIM swap, SIM change, or port-out fraud. This may help when speaking with banks, payment apps, credit bureaus, or law enforcement.

  7. Protect the email account that controls recovery. From a trusted device, change your email password, sign out of other sessions if available, and remove recovery phone numbers or devices you do not recognise. Then do the same for your carrier account and the most important financial accounts.

  8. Move critical accounts away from SMS codes when you regain access. Use an authenticator app, passkey, hardware security key, or in-app approval where the account offers it. Keep backup recovery options in a safe place so you are not forced back to the stolen number.

  9. If money moved or accounts changed, report it through official channels. Ask each bank or payment app how to dispute unauthorized activity. If your personal information was misused, make a recovery plan at IdentityTheft.gov. For online-enabled fraud, you can also report to the FBI’s IC3.

  10. If you are worried about new credit accounts, add credit protections. A fraud alert or credit freeze can make it harder for someone to open new credit in your name. This does not restore current bank access, so do it after you have contacted the bank and carrier unless a new-account risk is already obvious.

What can wait

  • You do not need to figure out exactly how the SIM swap or port-out happened today.
  • You do not need to contact every company at once; start with the bank or card issuer, the carrier, your main email, and any payment app that can move money.
  • You do not need to replace your phone immediately unless your bank, carrier, or a trusted technician gives a specific reason.
  • You do not need to decide today whether to change your phone number permanently.
  • You do not need to set up perfect security settings before you have stopped risky account activity.

Important reassurance

This is a recognised kind of account-takeover problem, and it can feel frightening because the phone number is tied to so many logins. The useful first move is not to solve everything at once; it is to stop money movement, secure the phone number, and protect the email account that can reset other accounts.

Scope note

These are first steps to stabilise the situation and reduce immediate harm. Later decisions, including disputes, complaints, identity theft recovery, or cybersecurity help, may need specialist support.
