What to Do When You Lose Your Phone

Losing your phone can be stressful, but acting quickly can help you recover it or protect your data. Start by using Find My Device (Android) or Find My iPhone (iOS) to locate your device. If you can’t retrieve it immediately, enable Lost Mode to lock your phone and display a contact message. Remote lock and erase features protect your sensitive information from unauthorized access. Contact your carrier to suspend service and prevent fraudulent charges. Finally, change passwords for critical accounts and file a police report if necessary. Taking these steps within the first few hours dramatically increases your chances of recovery while minimizing security risks.

Use Find My Device to Locate Your Phone

The first action you should take when realizing your phone is missing is to use the built-in tracking service. These tools work even if your phone is on silent mode and can help you determine whether you left it somewhere nearby or if it’s been stolen.

For iPhone users, access iCloud.com/find from any web browser or use the Find My app on another Apple device. Sign in with your Apple ID, and you’ll see your device’s current or last known location on a map. The service also shows battery level, which helps you act quickly if power is running low.

For Android users, navigate to google.com/android/find and sign in with your Google account. Google’s Find My Device displays your phone’s location and offers additional options like playing a sound at full volume for five minutes, even if the device is set to silent or vibrate mode.

Key features available through these services include:

  • Real-time location tracking with map view
  • Play sound to help locate nearby devices
  • View battery percentage and connection status
  • See when the device was last active
  • Display recent location history

If your phone appears to be moving or is in an unfamiliar location, do not attempt to retrieve it yourself. Instead, contact local law enforcement and provide them with the location information.

Activate Lost Mode and Remote Lock

Once you’ve located your device or determined it’s not immediately retrievable, enabling Lost Mode should be your next priority. This feature locks your device remotely and prevents unauthorized access to your personal information.

iPhone Lost Mode allows you to display a custom message on the lock screen with a contact phone number where someone who finds your device can reach you. The phone remains locked with your passcode, and Apple Pay is automatically disabled to prevent fraudulent transactions. All notifications are hidden from the lock screen to protect your privacy.

Android Lock works similarly by securing your device with your PIN, pattern, or password. You can display a message and phone number on the lock screen, and the device will sign out of your Google account on that phone to prevent access to Gmail, Photos, and other services.

Setting up Lost Mode or Remote Lock takes only a few minutes but provides crucial protection:

  • Prevents unauthorized access to apps and data
  • Disables payment methods and digital wallets
  • Displays your recovery message prominently
  • Continues tracking even while locked
  • Prevents the device from being powered off (on some models)

Contact Your Carrier Immediately

Even with your device locked, contacting your mobile carrier should happen within the first few hours of discovering your phone is missing. Carriers can take immediate action to protect you from unauthorized usage and fraudulent charges.

When you contact your carrier’s customer service, request the following actions:

  1. Suspend service temporarily – This prevents anyone from making calls, sending texts, or using your data plan while you search for the device
  2. Block the IMEI number – This unique identifier prevents the phone from being used on any network, making it essentially worthless to thieves
  3. Review recent activity – Check for any unauthorized calls, texts, or data usage since you lost the phone
  4. Discuss insurance options – If you have device insurance or protection plans, ask about the claims process

Major carriers provide 24/7 support for these situations:

Postpaid Carriers:

Prepaid Carriers:

According to the Federal Communications Commission, suspending service quickly prevents unauthorized charges and protects against identity theft attempts using your phone number.

Secure Your Accounts and Change Passwords

Your smartphone contains access to numerous sensitive accounts, from banking apps to social media. Even with a locked device, taking additional security measures protects against potential breaches.

Priority accounts to secure immediately:

Change passwords from a secure computer or another trusted device. Enable two-factor authentication (2FA) on all accounts that support it, using an authentication app rather than SMS codes since you don’t have access to your phone number temporarily.

Review recent account activity for suspicious logins or transactions. Most services show recent login locations and devices. If you spot unauthorized access, log out all sessions immediately and report the breach to the service provider.

Consider using a password manager like LastPass, 1Password, or Bitwarden to generate and store strong, unique passwords for each account. This prevents a compromised phone from giving thieves access to all your accounts through saved passwords.

Consider Remote Erase as a Last Resort

Remote erase is the nuclear option for protecting your data when recovery seems impossible. This feature permanently deletes all information from your device, including photos, messages, apps, and settings. Only use this option after carefully weighing the consequences.

When to consider remote erase:

  • Your phone contains extremely sensitive work or personal information
  • The device appears to be in the possession of someone with malicious intent
  • You’ve exhausted all recovery options over several days
  • The phone is showing signs of tampering or unauthorized access attempts
  • Insurance has approved your claim and you’re receiving a replacement device

Important warnings about remote erase:

Once you erase your device remotely, you can no longer track its location. The Find My Device feature stops working immediately after the erase completes. This means if someone finds your phone later, you have no way to locate it or prove ownership through tracking history.

How to perform a remote erase:

For iPhone:

  1. Go to iCloud.com/find and sign in with your Apple ID
  2. Click “All Devices” at the top of the screen
  3. Select the device you want to erase
  4. Click “Erase iPhone” in the device information panel
  5. Enter your Apple ID password to confirm
  6. Optionally add a phone number and message that will display on the device
  7. Click “Next” then “Erase” to confirm

The erase begins the next time your device connects to the internet. After erasing, your iPhone will require your Apple ID and password to set up again (Activation Lock).

For Android:

  1. Go to google.com/android/find and sign in
  2. Select your lost device from the list
  3. Click “Erase device” on the left side panel
  4. Review the warning about losing tracking capability
  5. Click “Erase device” again to confirm
  6. Sign in with your Google account password one more time

This action removes your Google account and resets the phone to factory settings. The device will require your Google account credentials to set up again, providing some protection against resale or reuse by thieves.

File a Police Report and Insurance Claim

Filing an official police report serves multiple purposes even if you don’t expect to recover your phone. The report documents the loss or theft, which insurers typically require for claims, and it helps law enforcement track theft patterns in your area.

Information to provide in your police report:

  • Date, time, and location where you last had the phone
  • Make, model, and color of the device
  • IMEI number (find this on your original packaging, purchase receipt, or carrier account)
  • Approximate value of the phone
  • Serial number if available
  • Any identifying features like cases, screen protectors, or custom engravings
  • Screenshots of Find My Device location if relevant

How to find your device information:

For iPhone:

  • Make and Model: Settings > General > About > Model Name (or check the back of your phone)
  • IMEI Number: Settings > General > About > IMEI (or dial *#06#)
    • Alternative: On original box, in iTunes/Finder when synced, or at appleid.apple.com under Devices
  • Serial Number: Settings > General > About > Serial Number

For Android:

  • Make and Model: Settings > About Phone > Model (exact location varies by manufacturer)
  • IMEI Number: Settings > About Phone > Status > IMEI (or dial *#06#)
    • Alternative: On original box, on SIM card tray, or at google.com/android/find (click the device, then the info icon)
  • Serial Number: Settings > About Phone > Status > Serial Number
    • Alternative: On original box or in your Google account under device management

Get a copy of the police report number immediately. Insurance companies, carriers, and tax deductions for business phones all require this documentation.

Filing an insurance claim:

If you have device insurance through your carrier, homeowner’s insurance, or renter’s insurance, file a claim promptly. Most policies have specific time limits for reporting losses.

Be aware of deductibles, which typically range from $50 to $250 depending on your phone’s value and your coverage type. Some policies have claim limits per year or may increase premiums after claims.

According to Consumer Reports, you should calculate whether the deductible plus remaining premium payments exceed the cost of replacing your phone out of pocket, especially for older devices.

Prevention Tips for Future Protection

After going through the stress of losing a phone, taking preventive measures ensures you’re better prepared if it happens again.

Enable tracking services before you need them:

Both Find My iPhone and Find My Device must be enabled in settings to work when needed. Check your settings now to verify these features are active.

For iPhone:

  1. Open Settings and tap your name at the top
  2. Tap “Find My”
  3. Tap “Find My iPhone”
  4. Toggle on “Find My iPhone”
  5. Toggle on “Find My network” (allows location even when offline)
  6. Toggle on “Send Last Location” (sends location before battery dies)

For Android:

  1. Open Settings
  2. Tap “Security” or “Security & location” (varies by device)
  3. Tap “Find My Device”
  4. Toggle on “Find My Device”
  5. Ensure “Location” is enabled in your main Settings
  6. Verify Google Play Services is up to date

Back up your data regularly:

Automatic cloud backups through iCloud (iPhone) or Google One (Android) ensure your photos, contacts, and important data survive even if you need to remote erase.

For iPhone:

  1. Open Settings and tap your name
  2. Tap “iCloud”
  3. Tap “iCloud Backup”
  4. Toggle on “Back Up This iPhone”
  5. Ensure you’re connected to Wi-Fi
  6. Tap “Back Up Now” to create an immediate backup
  7. Your iPhone will automatically back up daily when plugged in, locked, and connected to Wi-Fi

For Android:

  1. Open Settings
  2. Tap “System” then “Backup” (location varies by device)
  3. Toggle on “Back up to Google Drive”
  4. Select your Google account
  5. Toggle on “Automatic restore”
  6. Ensure “Photos” backs up to Google Photos separately (open Google Photos app > Profile > Photos settings > Backup)

Set backups to occur daily when connected to Wi-Fi for maximum protection.

Use strong security measures:

  • Enable biometric security (fingerprint or face recognition) in addition to a strong PIN
  • Set your phone to auto-lock after 30 seconds to one minute of inactivity
  • Disable lock screen notifications for sensitive apps
  • Don’t use easily guessable PINs like 1234, 0000, or birthdays

Record important information:

Store your phone’s IMEI number, serial number, and carrier account information in a secure location separate from your device. Take photos of your purchase receipt and keep them in cloud storage or email them to yourself.

Consider tracking accessories:

Attach an Apple AirTag or Tile tracker to your phone case as an additional tracking layer. These Bluetooth trackers work even when your phone’s battery dies and can help locate devices in your immediate area.

Practice phone security habits:

  • Keep your phone in secure pockets or bags, not on tables or car seats
  • Be aware of your surroundings when using your phone in public
  • Use phone grips or lanyards to prevent accidental drops and loss
  • Avoid leaving your phone unattended, even briefly
  • Consider a distinctive phone case that’s easily recognizable

The FCC’s smartphone security checker provides personalized recommendations based on your device and usage patterns, helping you identify security gaps before problems occur.
