Phone Theft: Prevention and Recovery

Your phone is your bank, your map, your translator, your boarding pass and your two-factor codes. That makes it the most valuable thing you carry, and in any big city, the most commonly taken. Losing it abroad is more than an inconvenience; it can lock you out of your money and your accounts.

This guide is in two parts: what to do now, and what to do in the first hour if it happens.

Part one: before

### Habits on the street

• Keep it out of sight. A phone held at the curb or on a cafe table near the street is easy to grab. Step into a doorway to check directions.
• Use a zipped pocket or bag. Front pockets are better than back pockets.
• Be careful at windows. In cars and buses, avoid holding the phone near an open window.
• Use earbuds less in busy places. They tell people you have a phone and make you less aware.

### Settings to change today

• Strong screen lock. A long PIN or passcode, not a short pattern.
• Turn on find-my-device and test it.
• Turn on stolen-device protections if your phone offers them. They add extra checks when changing important settings away from familiar places.
• Lock the SIM with a PIN, so the SIM cannot be used in another phone to receive your codes.
• Hide notifications on the lock screen, especially message previews that might show codes.
• Lock sensitive apps such as banking and email with their own PIN or biometrics.
• Turn on backups, so photos and contacts survive.

### Accounts

• Move two-factor codes off SMS to an authenticator app or passkeys where possible. See US mail, phone number and two-factor codes.
• Print backup codes for your email and banks, and keep them at home.
• Write down your phone's IMEI number, your carrier's support number and your banks' card-blocking numbers, on paper, at home.

### A spare

Some people keep an old phone at home with a spare SIM or eSIM ready. It turns a disaster into an errand.

Part two: the first hour

If your phone is taken, act quickly. Speed matters more than anything else.

1. Stay safe. Do not chase anyone.
2. From another device, mark the phone as lost with find-my-device, and erase it if you cannot recover it.
3. Call your banks and block cards and banking apps.
4. Change your email password, then the passwords of other important accounts, starting with banking and your password manager.
5. Call your carrier to block the SIM and the line. Ask how to get a new SIM with the same number.
6. Sign out of sessions in your email and messaging apps from another device.
7. Warn your contacts that messages asking for money from your number are not from you.

Part three: the following days

• File a police report (boletim de ocorrência). Insurers and carriers usually ask for it. See Emergency numbers.
• Ask your carrier whether the device can be blocked by IMEI.
• Restore a new phone from your backup.
• Review account activity for anything unusual.

Checklist

1. Set a strong screen lock and a SIM PIN.
2. Turn on find-my-device and stolen-device protections.
3. Move two-factor codes off SMS.
4. Print backup codes, IMEI and key phone numbers.
5. Keep the phone out of sight on the street.
6. Know your first-hour steps.

Common questions

Should I carry a second, cheaper phone? Some people do for nights out. It limits what you can lose.

Is phone insurance worth it? It depends on the cost and the terms. Read what is excluded before you buy.

Mistakes to avoid

• Keeping backup codes only on the phone. If the phone goes, so do the codes. Keep a printed copy at home.
• A short pattern lock. It can be seen over your shoulder. Use a longer passcode.
• Waiting to see if it turns up. Block cards and change your email password first. You can undo a block; you cannot undo a drained account.
• Forgetting your contacts. A stolen phone can be used to ask your friends for money. Warn them.
