  • Lock the phone first: android.com/find or icloud.com/find from any other device
  • Right after that: block the SIM and bank cards, sign out of accounts, and change passwords
  • Erase only if you can’t get the phone back, and never remove an iPhone from Find My

What to do if your phone is stolen: in the first hour, getting the phone back matters less than shutting the thief out. Lock the phone with Google’s Find Hub or Apple’s Find My, block your SIM card with your carrier, sign out of your accounts, and change your passwords. The police report, remote erase, and getting your number back come next.

Below is a step-by-step plan for Android and iPhone: what to tap, whom to call at Kyivstar, Vodafone, and lifecell in Ukraine, and what to turn on in advance. Menu names and terms were checked against Google, Apple, Samsung, and carrier help pages as of October 10, 2026. On Samsung and other brands, the Android settings path may differ slightly.

What to do if your phone is stolen: the first-hour plan

First, cut off the thief’s access to your data and money; then work on getting the phone and your number back.

Lock your Android phone with Find Hub

Google’s device-finding service is called Find Hub in English; the Russian and Ukrainian interfaces use local names for it. It turns on automatically when you add a Google Account to the phone.

  1. Open the Find Hub app on another Android device, or go to android.com/find in a browser. On someone else’s phone, choose Sign in as guest.
  2. Select the stolen phone. The map shows where it is now or, if that’s unknown, its last known location.
  3. Tap Mark as lost, then Next, then Mark as lost again.

The phone locks with your PIN, pattern, or password, and access to notifications, widgets, and quick actions is turned off. On Android 17 with a fingerprint sensor or Face Unlock, you can also require biometrics to unlock it. The command goes through if the phone is on and connected to the internet.

If you don’t have your Google password at hand, go to android.com/lock: there you lock the screen with your phone number, the answer to your security question (if you set one), and a reCAPTCHA check. This works if Remote Lock was turned on in advance, the phone has an active SIM card, and the number is verified. If the phone is offline, the screen locks once it connects to the internet. You can lock a phone remotely twice in 24 hours.

Samsung Galaxy phones also have their own service, Samsung Find (plus SmartThings Find). It lets you lock the phone with a separate PIN, erase it, get its location every 15 minutes, and turn on Maximum power saving mode so the battery lasts longer. The phone must be signed in to a Samsung account.

Result: The stolen Android phone’s screen is locked, and notifications and quick actions are off.

Turn on Lost Mode on your iPhone

  1. Go to icloud.com/find and sign in to your Apple Account. You don’t need a verification code: if the site asks for one, select the Find Devices button instead.
  2. Under All Devices, select your iPhone.
  3. Choose Mark as Lost and follow the onscreen instructions.

You can do the same in the Find My app on an iPad, a Mac, or a family member’s iPhone: Devices tab → your iPhone → More → Lost [Device] → Activate. We explain how to open iCloud on a Windows PC or Mac in a separate guide.

In Lost Mode, the iPhone asks for its passcode, and the payment cards and passes in Apple Pay are suspended. If Stolen Device Protection is on, Lost Mode can be turned off only with Face ID or Touch ID — even by someone who knows the passcode. Apple still recommends marking a stolen iPhone as lost: the extra safeguards of Stolen Device Protection last only for a period of time.

If the phone was stolen rather than lost, don’t add a phone number or a message for the finder: Apple warns that a thief might use your contact information for scams. If Find My wasn’t turned on, the iPhone won’t show up in the app or on the website — in that case, change your Apple Account password right away.

Result: The iPhone is locked with your passcode, and Apple Pay cards on it are suspended.

Block your SIM card with your carrier

Codes from banks, email, and messaging apps arrive at your number, so block the SIM card right away, even if it has a PIN. Call from another phone:

CarrierNumber to callHow to prove the number is yours
Kyivstar477, 0 800 300 466, or a storeNumber details, SIM holder with PUK
Vodafone222 or 0 800 400 222PUK or two frequently called numbers
lifecell5433, 0 800 20 5433, or a storeSecret word or frequent numbers
0 800 numbers are free from all networks in Ukraine. Carrier details as of October 10, 2026.
  • Kyivstar. You can also suspend the number in the My Kyivstar app. Choose loss of the SIM card as the reason: the number then stops registering on the network, and you can get it back only at a Kyivstar store with an ID document or Diia (from abroad, via chat). The suspension is free for up to six months, and the plan fee isn’t charged.
  • Vodafone. To verify your identity, give the PUK code (8 digits on the plastic SIM holder) or two numbers you called or texted most often in the last 30 days. If the number is registered to your passport, give your full name and document details.
  • lifecell. In the 5433 menu, choose SIM card blocking. The first five days of blocking are free; from day six, keeping the number costs UAH 0.20 a day.

Google notes that a carrier can use the IMEI to find a phone or pause service. Ask whether your carrier offers this when you block the SIM card.

Result: Your number no longer works in the stolen phone, but it still belongs to you.

Block your cards and warn your family

If the phone had banking apps or cards for contactless payments, block the cards in your bank’s app on another device or through the bank’s hotline. Kyivstar also suggests asking the bank to unlink your number from your cards. Lost Mode on an iPhone suspends Apple Pay cards on its own.

Over the next few days, check your statements and report suspicious charges to your bank, as Google advises. Warn your family and friends: Ukraine’s State Special Communications Service points out that someone may ask them for money in your name from the stolen phone.

Result: Your cards are blocked, and your family knows not to trust money requests from your number.

Sign out of your accounts on the stolen phone

  • Google. In your Google Account, open the Security tab, find “Your devices,” select Manage devices, choose the phone, and next to “Account Access,” select Sign out. On someone else’s computer, use a private (incognito) window.
  • Apple. On an iPad or Mac, go to Settings (or System Settings) → your name and scroll down to your device list. Remove the stolen iPhone from your account, but not from Find My. Remove any devices you don’t recognize, too.
  • Telegram. On a computer or tablet, go to Settings → Devices and end the session on the stolen phone. Telegram recommends turning on Two-Step Verification in Privacy and Security right away: without it, the phone number alone is enough to sign in.
  • WhatsApp. You can’t sign out remotely — not from another device and not through WhatsApp Web. Restore your number on a new SIM card and register WhatsApp again: the stolen phone is logged out automatically. WhatsApp itself can’t deactivate the account for you.

Check the list of active sessions in other services that have one, too: email, social media, banking apps.

Result: Your email, cloud storage, and chats are closed off on the stolen phone.

Change your passwords

Start with your email and your phone’s main account: other passwords are reset through them. You change your Google password in the Security section of your Google Account, and passwords.google.com shows which passwords are saved to your account — change them on the sites and in the apps that were open on the phone.

For your Apple Account, go to Settings → your name → Sign-In & Security on another trusted device. Review your email, phone numbers, and recovery methods. If you see changes you didn’t make, fix them and change your password. On a new device, Apple may set a waiting period before you can change security settings.

Then move on to online banking, messaging apps, social media, and Diia. If you have many passwords, a password manager makes this easier: here’s our comparison of password managers.

Result: Passwords saved on the stolen phone no longer work.

Report the theft to the police

Ukraine’s National Police ask people to report crimes on the 102 line, which works around the clock. You can also file a report at the nearest police station. The online form on the police website is meant for citizens’ appeals, not for urgent crime reports.

Bring an ID document and write down the IMEI and serial number: Apple and Google note that the police may ask for them. Here’s how to find them without the phone:

  • on the box — the serial number and IMEI are next to the barcode;
  • iPhone — at account.apple.com under Devices, or on another Apple device: Settings → your name → your iPhone’s name;
  • Android — in Find Hub: select the phone and tap the Settings icon (on android.com/find, it’s next to the device name).

If the phone shows up on the map, give the address to the police. Don’t go there yourself — more on that below.

Result: The police know about the theft and have the phone’s IMEI and serial number.

Erase the phone if you can’t get it back

Erasing is the last resort: Apple advises trying everything else to find the device first, because erased data can’t be restored.

  • Android. In Find Hub, select the phone and tap Settings → Factory reset. All data is deleted, though files on an SD card may remain. After the reset, the phone disappears from Find Hub, and you’ll need your Google Account password to use it again.
  • Samsung Galaxy. In Samsung Find, select the phone and the option to erase its data. If the phone is found later, unlocking it will require signing in to the Google Account that was on it.
  • iPhone. At icloud.com/find, select the iPhone → Erase This Device. With iOS 15 or later, you can still locate the phone after erasing it. Don’t remove it from Find My: that removes Activation Lock, which keeps anyone from activating the iPhone without your Apple Account password even after it’s erased.

If the iPhone is offline, the erase starts the next time it connects. Until then, you can cancel the request at icloud.com/find.

Result: The data on the phone is erased, and it can’t be used without your account password.

Restore your number and data

A blocked number doesn’t disappear: it’s moved to a new SIM card at a carrier store. At lifecell, you need a passport, driver’s license, military ID, pension certificate, or Diia; a new SIM card costs UAH 75 and an eSIM UAH 100 (as of October 10, 2026). Your plan, balance, and services are kept. At Kyivstar, a number suspended because of a lost SIM card is restored at a store with an ID document or Diia.

If you’d like to switch to a virtual SIM right away, ask your carrier about an eSIM — see our guide on how to get an eSIM in Ukraine. On the new phone, restore your data from a Google or iCloud backup, sign in to WhatsApp with the new SIM card, and check in Telegram that the old session has ended.

Result: Your number works on a new SIM card, and your data is back from a backup if you had one.

If the phone is already off or offline

You can’t lock a phone that’s switched off in that very second, but send the commands anyway: some of them take effect the next time it connects. And blocking the SIM card, contacting the bank, changing passwords, and reporting to the police don’t depend on the phone at all.

  • iPhone. With Find My network turned on, a supported iPhone can be located for up to 24 hours after it’s turned off, or up to 5 hours in power reserve mode. If the battery has run out, Find My shows its last known location for up to seven days. Lost Mode turns on and the erase starts when the iPhone is back online.
  • Android. If offline finding with the network is on, Find Hub can locate supported models (such as the Pixel 8 series) for several hours after they’re turned off. Otherwise, you see the last known location, if it was saved. A request from android.com/lock locks the screen as soon as the phone connects to the internet.
  • Offline Device Lock. If it’s on, Android locks the screen shortly after a thief cuts the internet connection on an unlocked phone.
  • Samsung Galaxy. If the phone is turned off, Samsung Find shows only its last known location.

What not to do

  • Don’t go after the phone yourself, even if you see it on the map. Apple and Samsung advise giving the location to the police.
  • Don’t show your phone number or a message on the stolen iPhone’s screen.
  • Don’t remove the iPhone from Find My, even after erasing it.
  • Don’t rush to erase an Android phone: after a reset, you can’t find it in Find Hub anymore.

How to prepare in advance

Almost everything that helps you find a phone, or at least protect your data, has to be turned on before it’s stolen: you can’t change the settings afterward.

Android

  • Find Hub. Settings → Security → Find Hub: “Allow device to be located” should be on. Then go to Settings → Google → All services → Find Hub → Find your offline devices and choose With network everywhere or With network in busy places only.
  • Theft protection. Settings → Google → All services → Theft protection. Turn on Theft Detection Lock (the phone senses when someone snatches it and runs), Offline Device Lock, Remote Lock with a verified number, and, if available, Identity Check. You need a screen lock and Android 10 or later; some features need Android 15. Theft protection isn’t available on Android Go devices, tablets, or wearables.
  • Google backup codes. If your second sign-in step goes to this same phone, without backup codes or a security key you may not be able to sign in to lock it. To get codes: Google Account → Security & sign-in → 2-Step Verification → Backup codes.

iPhone

  • Find My. Settings → your name → Find My → Find My iPhone: turn on Find My iPhone, Find My network, and Send Last Location.
  • Stolen Device Protection. Settings → Face ID & Passcode → Stolen Device Protection (iOS 17.3 or later; it might be on by default). Away from home and work, saved passwords and cards open only with Face ID or Touch ID, and your Apple Account password can be changed only after a one-hour security delay. The feature requires two-factor authentication, a passcode, Face ID or Touch ID, and Significant Locations turned on.

For any phone

  • Screen lock. Google recommends a PIN of six or more characters, a complex pattern, or a unique password — even if you unlock with your fingerprint.
  • SIM PIN. You’ll be asked for it every time the phone turns on and whenever the SIM card goes into another phone. On Android, the path from Google’s help is Settings → Security & Privacy → More Security Settings → SIM Lock (it may differ by brand); on iPhone, it’s Settings → Cellular → SIM PIN. Some carriers use a default PIN that is publicly known — change it. Never guess your PIN or PUK: a wrong guess can lock the SIM card permanently.
  • IMEI, box, and SIM holder. Keep a copy of the IMEI and serial number somewhere other than the phone: on Android, they’re in Settings → About Phone; on iPhone, in Settings → General → About. Keep the box and the plastic SIM holder with the PIN and PUK: lifecell accepts a box showing the IMEI as proof the number is yours.
  • Register your number. Vodafone and lifecell recommend registering your number to your own ID: such a number is harder to steal. Vodafone offers the “Обмеження віддаленої заміни SIM-картки” service (restricted remote SIM replacement), so the SIM card can be replaced only in person at a store.
  • Backups and sign-in without SMS. Turn on Google or iCloud backup, and for email and banking, set up two-factor authentication with an authenticator app or a passkey instead of SMS.

Troubleshooting

  • The phone isn’t in Find Hub — it must be signed in to your Google Account and must not be hidden in Google Play (play.google.com/library/devices). If it’s not there, move on to the SIM card, passwords, and bank.
  • The iPhone disappeared from the map on icloud.com/find — with Stolen Device Protection, this can happen after someone tries to change the Apple Account password in an unfamiliar location. Turn on Lost Mode anyway.
  • Google asks for a code that goes to the stolen phone — use a backup code, another phone signed in to your account, or a passkey. If you have none of these, restore your number on a new SIM card.
  • The carrier won’t confirm the number is yours — lifecell considers frequently called numbers, the SIM holder, a box with the IMEI, and payment receipts; Vodafone asks for the PUK or two numbers from the last 30 days.
  • The lock from android.com/lock didn’t work — check the answer to your security question: with a wrong answer, Remote Lock doesn’t work. The limit is twice in 24 hours.

FAQ

Can I find a stolen phone by its IMEI?

Not on your own: Google and Apple locate phones through your account, not by IMEI. The police need the IMEI, and according to Google, a carrier can use it to find a phone or pause service.

How do I lock a stolen phone that’s turned off?

Send the command anyway. Lost Mode on an iPhone turns on, and a request from android.com/lock locks an Android phone, as soon as the phone connects to the internet. While it’s offline, block your SIM card, bank cards, and accounts — none of that depends on the phone.

Will I keep my number after blocking the SIM card?

Yes. The number stays yours, and a carrier store issues a new SIM card with it when you show an ID document. Kyivstar suspends a number for free for up to six months; at lifecell, the first five days of blocking are free, then it’s UAH 0.20 a day.

I got a message saying my iPhone was found. What should I do?

Don’t enter anything and don’t call back. Apple never contacts you to say an iPhone was found, and it asks you never to share your Apple Account password, passcode, or verification codes.

Should I erase a stolen phone right away?

Not right away. After a reset, an Android phone disappears from Find Hub, while an erased iPhone with iOS 15 or later still shows up in Find My. Lock the phone and try to find it first, and erase it once there’s no hope of getting it back.
