Phone Lost or Stolen? What to Do Immediately on Android and iPhone (2026 Guide)

Lost or stolen smartphone security guide showing location tracking, device locking and account protection.

Knowing what to do if your phone is lost or stolen can protect much more than the device. It may contain your email, messages, photos, saved passwords, payment services, authentication prompts and access to other accounts. The safest response is to locate and lock it first, then protect your phone number, accounts and money in a deliberate order.

Quick answer: Call the phone if it may be nearby, use Google Find Hub or Apple Find My immediately, mark the device as lost, save its location and identifying details, contact your mobile carrier, report theft to local authorities and remotely erase the phone only when recovery is unlikely or sensitive data remains at risk.
Personal-safety warning: A map location is not permission to confront anyone. If the phone appears at an unfamiliar address, is moving or was taken by force, save the information and contact local law enforcement. Apple and Samsung both specifically advise users not to recover a stolen device themselves.57

The First 10 Minutes After Your Phone Goes Missing

First ten-minute checklist for locating and securing a missing smartphone.

Speed matters, but panic causes mistakes. Work through these actions from another trusted phone, tablet or computer. If you must use a public or borrowed device, use a private browser window, do not save passwords and sign out completely when finished.

  1. Call your number. If the phone may be in your home, office, car, shop or another safe place, call it and listen. Do not reveal sensitive information in a voicemail or lock-screen message.
  2. Open the official location service. Android users should go to Google Find Hub. iPhone users should go to iCloud.com/find or use Find My on another Apple device.
  3. Play a sound if the location is familiar. This is useful when the phone is nearby, even if it was set to silent. Do not repeatedly ring a phone you believe was stolen.
  4. Mark the device as lost or secure it. Add a safe return message only when the phone appears genuinely misplaced. For a confirmed theft, avoid displaying personal details that could be used for impersonation.
  5. Save evidence. Take screenshots of the device name, approximate location, time, serial number and IMEI when available. Keep receipts, the box and any police or carrier reference numbers.
  6. Contact your carrier and authorities. Ask the carrier to suspend the SIM or eSIM and explain its IMEI-blocking process. Report theft, robbery or snatching to the appropriate local law-enforcement agency.

Google says Find Hub can locate, ring, mark as lost and erase a supported Android device. It can also show the phone’s IMEI for a carrier report.1 Apple says iCloud.com/find does not require the missing trusted phone’s verification code when you enter through Find Devices, which is important when that iPhone was your normal two-factor device.6

Is the Phone Lost, Stolen or Simply Offline?

Your next action depends on what the available evidence shows. Treat uncertain situations cautiously.

Situation Useful first action What not to do When to escalate
Probably nearby Call it, play a sound and check recent safe locations Do not erase it while you are still searching nearby Escalate if the map begins moving or an unknown person answers
Lost in a public place Mark it as lost and provide a separate contact number Do not place your home address, account email or other sensitive details on the lock screen Contact the venue, transport operator and carrier
Probably stolen Lock it, save evidence and report it Do not travel to the map location or negotiate with a thief Contact local law enforcement, the carrier and financial providers when necessary
Offline or powered off Enable the lost command anyway and review the last known location Do not assume that “offline” means the tracking command failed permanently Protect accounts if the phone was unlocked, stolen or missing for an extended period

A location pin is an estimate. Google explains that accuracy may come from GPS, nearby Wi-Fi or cell towers and can range from relatively precise to several kilometers.1 Use the map as evidence and guidance—not as proof that a particular person has the device.

How to Find, Lock or Erase a Lost Android Phone

On another Android device, open the Find Hub app. On a computer, iPhone or other browser, visit android.com/find and sign in with the Google Account used on the missing phone.

Use Google Find Hub

  1. Select the missing device. Check the phone model and account carefully if several devices appear.
  2. Review its current or last known location. Save a screenshot with the time. If the phone is nearby and the place is safe, use Play sound.
  3. Choose Mark as lost. This locks the phone with its existing PIN, pattern or password. You can add a return message and safe contact number.
  4. Record the IMEI. Open the device settings inside Find Hub. Your carrier may use the IMEI to disable the handset on supported networks.
  5. Use Factory reset only when necessary. Android warns that remote erasure permanently deletes device data, may not delete an SD card and normally ends further location access in Find Hub.1

For remote security and erasure, Google lists several requirements: the phone generally needs power, an internet connection, a signed-in Google Account, Find Hub enabled and visibility in Google Play. Its offline-finding network may still provide a recent encrypted location when the supported settings were enabled in advance.2

Remote Lock may help when sign-in is difficult: On a supported phone configured beforehand with a verified number, screen lock and Find Hub, Google’s Remote Lock can be requested at android.com/lock. If the phone is offline, the lock is applied when it reconnects.3

If Find Hub does not show the phone

  • Confirm that you selected the correct Google Account.
  • Check all devices and recent account activity at Google Account device activity.
  • Try again later in case the phone reconnects or the offline network reports a new location.
  • Contact the carrier to suspend the SIM or eSIM and ask about IMEI blocking.
  • If unauthorized account changes appear, follow Google’s official compromised-account process immediately.8

Extra Options for a Missing Samsung Galaxy Phone

A Galaxy phone may appear in both Google Find Hub and Samsung Find when the necessary Google and Samsung settings were enabled beforehand. Visit Samsung Find / SmartThings Find, sign in with the Samsung Account used on the missing device and select the phone.

Samsung’s current support guidance includes options to locate, ring, track, lock and erase supported Galaxy devices. Some devices can also use offline finding or extend battery life remotely. Feature availability depends on the model, software, country and settings.7

Use both services carefully

Check Google Find Hub and Samsung Find because one service may have a more recent location or a useful device-specific control.

Do not erase too early

Samsung warns that erasing permanently deletes the data and can end remote control and location through Samsung Find. Lock and document first unless immediate erasure is necessary.

Android and iPhone recovery options compared for locating, locking and erasing a missing phone.

How to Find, Mark as Lost or Erase an iPhone

Use the Find My app on another trusted Apple device or visit iCloud.com/find. Choose the missing iPhone under All Devices.

Use Apple Find My and Lost Mode

  1. Check the map and play a sound when appropriate. Save the location and time before it changes.
  2. Choose Mark as Lost. Lost Mode locks the iPhone with its passcode and suspends supported payment cards and passes used with Apple Pay.6
  3. Add contact information only when sensible. A separate number can help an honest finder return a misplaced phone. Apple advises against displaying personal contact information on a confirmed stolen phone because thieves may use it for social engineering.5
  4. Report theft. Save the serial number and map evidence, then contact local law enforcement and your wireless carrier.
  5. Erase only after considering recovery. Erasure cannot be undone. On supported devices with iOS 15 or later, Find My may remain available after remote erasure, but the iPhone must stay in your Find My list.5
Never remove a stolen iPhone from Find My. Apple says removing it disables Activation Lock and makes the phone easier to erase and resell. Keep it associated with Find My even after a remote erase or while an eligible theft-and-loss claim is being processed.5

If Find My was not enabled before the phone disappeared, it cannot be switched on remotely. Apple recommends changing the Apple Account password immediately when the stolen device cannot be marked as lost or erased through Find My.5

What Stolen Device Protection changes

Stolen Device Protection adds biometric checks and, for some sensitive changes, a security delay when an iPhone is away from familiar locations. It can restrict access to saved passwords, payment information, account changes and the ability to turn off Lost Mode. The feature must have been enabled before the theft and requires iOS 17.3 or later on a supported iPhone.10

Protect the SIM, eSIM and IMEI

Locking the phone protects the device, but your phone number also matters. A stolen SIM can receive calls or text-message codes when the account and carrier controls allow it. Contact the mobile carrier through its official website, app, published number or physical store.

Suspend the line. Ask the carrier to stop service on the missing SIM or eSIM.
Request a replacement. Move the number to a new SIM or eSIM only after the carrier verifies your identity.
Report the IMEI. Ask whether the carrier or national regulator can block the handset on participating mobile networks.
Keep both IMEIs. Dual-SIM phones may have two IMEI numbers, and the reporting authority may require both.
Save reference numbers. Keep carrier, police, insurer and regulator case numbers together.
Warn trusted contacts. Tell them not to trust urgent money requests or verification-code requests from your number.

IMEI blocking is not remote erasure, account protection or guaranteed recovery. It is a network-level measure intended to restrict a reported handset on participating cellular networks. The exact process varies by country, carrier and regulator.

Protect Your Email, Passwords, Messages and Money

Your primary email account is often the reset key for many other services. A password manager may hold credentials, while the phone number may receive recovery codes. After the device is locked and its location evidence is saved, review the accounts that could be reached from it.

Prioritize accounts in this order

  1. Primary email and cloud account. Review recent sign-ins, recovery details, trusted devices and security alerts. Change the password immediately if the phone was unlocked, your passcode was observed or unauthorized activity appears.
  2. Password manager and passkeys. Remove the lost device or its passkey where the service supports it. Google provides a specific process for removing a passkey associated with a lost device.12
  3. Banking, wallets and payment services. Contact the financial provider through its official app, website or the number printed on a physical card. Report unauthorized transactions immediately.
  4. Messaging and social accounts. End unrecognized sessions, move the account to the replacement SIM when supported and warn contacts about impersonation.
  5. Work or school access. Notify the organization’s IT or security team. A managed device may have additional remote-lock, certificate-revocation or data-removal controls.

When an iPhone is placed in Lost Mode, Apple says supported Apple Pay cards and passes are suspended.6 For any platform, still review transactions and contact the bank or card issuer if the thief may have known the device passcode or if suspicious activity appears.

Do not approve unexpected sign-in prompts, password resets, SIM-transfer requests or two-factor codes. Google says verification codes should never be shared, and it recommends keeping backup codes somewhere safe so losing the phone does not lock you out of your own account.11

Should You Remotely Erase a Lost or Stolen Phone?

Remote erasure is an important last line of defense, but it changes what you can do next. Do not choose it only because the phone has been missing for a few minutes.

Question Android iPhone
When is erasure reasonable? Recovery appears unlikely, the device contains sensitive information or lock protection is uncertain Recovery appears unlikely, sensitive data remains at risk or Apple’s stolen-device procedure recommends moving to erasure
Can the action be undone? No; factory reset permanently deletes device data No; remote erase cannot be undone
What happens to tracking? Google says the phone’s location is no longer available in Find Hub after erasure Apple says supported devices with iOS 15 or later may remain locatable after erasure
What must remain linked? Keep records of the Google Account, IMEI, carrier report and police report Keep the iPhone in Find My so Activation Lock remains enabled
What may remain? Google warns that an SD card may not be erased Carrier, insurer and account records remain separate from the device erase
A practical decision rule: Lock first, document second, report third and erase when the privacy risk is greater than the remaining recovery value. If the phone was taken while unlocked or the thief knows the passcode, the balance may shift toward faster account protection and erasure.

Avoid “We Found Your Phone” Phishing and Recovery Scams

After a theft, criminals may text or call the replacement number, a family member or a contact displayed on the lock screen. They may pretend to be Apple, Google, the carrier, police, a repair shop or an honest finder. Their goal may be to obtain the device passcode, account password, verification code or permission to remove the phone from your account.

Type official addresses yourself. Use android.com/find, iCloud.com/find or the provider’s verified app instead of a message link.
Never reveal the screen passcode. A legitimate finder does not need it to return the phone.
Never share verification codes. Do not read out SMS, email, authenticator or recovery codes.
Keep the device linked. Do not remove a stolen iPhone from Find My because someone claims removal is required.
Verify calls independently. Hang up and call the carrier, bank or insurer using its published number.
Preserve threatening messages. Screenshot them and provide them to the appropriate authorities.

Apple states that it will not contact users to say a missing iPhone has been found and warns users never to share a device passcode, password or verification code.5 Treat the same information as secret regardless of the phone brand.

Report the Device Through Official Channels in Your Country

The reporting route is different in every country, but the basic order is widely applicable: suspend the mobile line through the carrier, report theft to the appropriate local law-enforcement agency, notify the insurer when the device is covered and ask the carrier or national telecommunications authority whether stolen-handset IMEI blocking is available.

Prepare the details that official organizations commonly request:

  • Every IMEI associated with the phone’s SIM slots;
  • The affected phone number and mobile carrier;
  • The phone’s brand, model and color;
  • The serial number and proof of purchase or ownership;
  • The date, approximate time, place and circumstances of the loss or theft;
  • Location screenshots or other evidence that can be shared safely; and
  • Carrier, police, insurer or regulator case numbers.

The IMEI may be printed on the original box, purchase document or device-account record. Google Find Hub can also show the IMEI for a listed Android device. For a dual-SIM phone, record both IMEIs. Keep every official reference number because you may need it for an insurance claim, follow-up report or unblocking request if the handset is recovered.

Use only official channels: Do not post your government ID, IMEI, phone number, police report or account credentials publicly or send them to an unofficial “recovery agent.” Find the correct carrier, police, insurer or regulator website independently and submit sensitive details only through its verified process.

Worldwide-reader note: Some countries operate a national stolen-device register, while others handle reports through individual carriers or law-enforcement agencies. IMEI blocking may apply only to participating networks and does not erase the phone, secure online accounts or guarantee recovery.

What to Do After the Phone Is Recovered

A phone found under a sofa is different from one recovered after theft. Take more precautions when another person may have handled or unlocked it.

  1. Recover it safely. Use the police or venue’s lost-property process when the device was stolen or found at an unfamiliar location.
  2. Inspect the device and SIM. Check for physical damage, an unfamiliar SIM, signs that the phone was opened or unexpected accessories connected to it.
  3. Turn off Lost Mode only on the recovered device or through the official service. Authenticate with your own credential.
  4. Review security activity. Check Google, Apple, Samsung, email, banking, messaging and social accounts for unknown sign-ins or changes.
  5. Install updates and back up important data. If the device behaved strangely or was unlocked while outside your control, seek trusted technical support and consider a carefully planned factory reset.
  6. Restore carrier and regulator status. Ask the carrier to reactivate the line. If an IMEI was blocked, use the same official process and reference number to request unblocking.

If the phone was remotely erased, set it up as a recovered device only after confirming that the Google, Apple or Samsung Account is secure. Restore from a backup you trust, then review app permissions, screen-lock settings, payment cards and account recovery methods.

Prepare Now—Before a Phone Disappears

The best time to configure recovery is while the phone is still in your hand.

Use a strong screen lock. Choose a long PIN or password and add biometrics for convenience.
Enable location recovery. Check Find Hub and offline finding on Android or Find My network on iPhone.
Turn on theft safeguards. Review Android Theft protection controls or iPhone Stolen Device Protection.
Back up automatically. Confirm that photos, contacts, messages and important files have a current backup.
Save device details elsewhere. Keep the serial number, both IMEIs, model, receipt and insurer information outside the phone.
Prepare account recovery. Add recovery contacts or methods and store two-factor backup codes securely.
Hide sensitive lock-screen content. Do not expose complete messages, verification codes or account details.
Protect the SIM. Consider a SIM PIN after learning the carrier’s correct default PIN and storing the PUK safely.

Google says supported Android theft controls can include Offline Device Lock, Failed Authentication Lock, Remote Lock and Identity Check; availability varies by device and software.3 Apple’s Stolen Device Protection can require biometrics and security delays for critical changes, and it can be set to apply those stronger requirements even in familiar locations.10

Final takeaway: Locate and lock the phone before changing everything. Preserve evidence, protect the phone number and primary accounts, use only official recovery services and erase the device only after understanding what tracking or recovery capability will be lost.

Frequently Asked Questions

Can I find a phone that is switched off?

Sometimes you can see a last known location or receive an offline-network location if the phone and recovery settings support it. Some supported devices may remain findable for a limited time after power loss. You generally cannot enable these features after the phone has already disappeared.

Should I change my Google or Apple password immediately?

First use the official locating service to lock the device and save evidence when possible. Change the password immediately if the phone was unlocked, the thief may know the passcode, Find My or Find Hub was unavailable, or unauthorized account activity appears. Then review recovery details and trusted devices.

Will changing my password erase the phone?

No. A password change and remote device erase are different actions. Password changes can sign out account sessions, but use Find Hub or Find My for the platform’s remote lock and erase controls.

Can police track a phone using the IMEI?

Capabilities and procedures vary by country and agency. Provide the IMEI, serial number, location screenshots, proof of ownership and incident details through the official police process. An IMEI block alone does not show you the phone’s live location.

Does blocking the IMEI delete my photos and accounts?

No. IMEI blocking restricts the handset on participating mobile networks. It does not remotely erase local data, change passwords or secure cloud accounts. Use the phone maker’s locating service and the relevant account-security controls as well.

What happens when I mark an iPhone as lost?

Lost Mode locks the iPhone with its passcode and suspends supported Apple Pay cards and passes. The device can display return information when appropriate. Keep a stolen iPhone in Find My so Activation Lock remains enabled.

What happens when I mark an Android phone as lost?

Find Hub locks the phone with its existing screen credential and can display contact information or a message. Available controls depend on the device, Android version, connection and settings configured before the loss.

Should I remotely erase the phone immediately?

Not when the phone is probably nearby and securely locked. Consider erasure when recovery is unlikely, sensitive data is exposed or the thief may know the passcode. Remember that Android normally stops reporting location through Find Hub after erasure.

Can someone use my eSIM after stealing the phone?

An eSIM is built into the device rather than removed like a physical SIM, but the phone number and carrier account still need protection. Ask the carrier to suspend the line and move it to a replacement device after verifying your identity.

What information should I put in a Lost Mode message?

For a genuinely misplaced phone, use a separate contact number and a short return request. Do not display your home address, account email, passwords or other sensitive information. For confirmed iPhone theft, Apple advises against adding contact details that could support social engineering.

How do I know whether a “your phone was found” message is real?

Do not trust the message link. Open android.com/find, iCloud.com/find or the provider’s verified app yourself. Never provide the screen passcode, password, verification code or permission to remove the phone from your account.

How do I report a stolen phone in my country?

Start with your mobile carrier to suspend the SIM or eSIM and ask about IMEI blocking. Report theft through the official local law-enforcement process, contact the insurer if the device is covered and check whether your national telecommunications authority maintains a stolen-device reporting system.
