How to Find a Lost iPhone or Android Phone

Losing your phone is stressful. Your contacts, photos, messages, and financial apps are all on that device. The good news is that both Apple and Google have built tools specifically for this situation. Apple's tool is called Find My. Google's tool is called Find My Device. Both can show you where your phone is on a map, make it play a loud sound, lock it so no one else can use it, and — as a last resort — erase all data on it remotely.

There is one critical requirement: these tools must be turned on before your phone goes missing. You cannot set them up after the fact. This guide shows you how to verify the feature is enabled right now, and then walks through exactly what to do if your phone ever goes missing.

Why setting this up now matters

If Find My or Find My Device is not enabled on your phone and it goes missing, you have very limited options. You can call your carrier (AT&T, Verizon, T-Mobile, etc.) to report it stolen, and they can disable service to the phone, but you cannot see its location or remotely erase your data. Taking five minutes to confirm the feature is on today may save you significant trouble later.

Setting up Find My on iPhone

Find My has two parts: Find My iPhone (which lets you locate your own phone) and Find My network (which can locate a phone even when it is offline by using nearby iPhones to relay its location). Both should be turned on.

To verify: Open the Settings app. Tap your name at the very top of Settings — this opens your Apple ID settings. Tap "Find My." Then tap "Find My iPhone." Make sure the toggle at the top is green (on). Also make sure "Enable Offline Finding" is green and "Send Last Location" is green. If any of these toggles are off, tap them to turn them on.

For Find My to work, your iPhone also needs to be signed in to your Apple ID. If you are not sure whether you are signed in, look at the very top of Settings — your name and email address should be displayed there. If it says "Sign in to your iPhone" instead, tap that and enter your Apple ID and password.

Setting up Find My Device on Android

On Android phones (Samsung, Google Pixel, Motorola, and others), the feature is called Find My Device and is managed by Google.

To verify on most Android phones: Open Settings, then tap "Security" or "Security & privacy" (the exact name varies slightly by phone brand). Look for "Find My Device" and tap it. Make sure the toggle is turned on. If you do not see it under Security, you can also search for "Find My Device" in the Settings search bar at the top.

Your phone must also be signed in to a Google account. To check: in Settings, tap "Accounts" or "Accounts & backup," then look for your Gmail address. If no Google account is listed, you will need to add one — tap "Add account" and follow the steps to sign in with your Google email and password.

Using Find My on iPhone when your phone is missing

If your iPhone is lost or missing, you have three ways to use Find My:

Option 1 — From another iPhone or iPad: Open the Find My app (it has a green icon with a radar circle). Tap the Devices tab at the bottom. Your iPhone should appear in the list with its last known location on a map. Tap your phone's name to see options: Play Sound (makes the phone ring at full volume for two minutes, even if it is on silent), Mark as Lost (locks the phone with a passcode and displays a message like your phone number so someone who finds it can contact you), and Erase This Device (permanently deletes all data — use this only as a last resort).

Option 2 — From a computer browser: Go to icloud.com and sign in with your Apple ID. Click "Find iPhone" (or "Find My" if shown). Your devices appear on a map. Click your phone to see the same Play Sound, Lost Mode, and Erase options.

Option 3 — Ask Siri on another Apple device: Say "Hey Siri, find my iPhone." Siri can trigger the sound remotely from an Apple Watch or iPad logged in to the same Apple ID.

Using Find My Device on Android when your phone is missing

Option 1 — From a computer browser: Go to android.com/find and sign in with the same Google account that is on your lost phone. A map appears showing the phone's last known location. You will see three options: Play sound (rings the phone at full volume for five minutes), Secure device (locks the phone and signs out of Google — you can also leave a message and phone number on the lock screen), and Erase device (permanently deletes all data on the phone).

Option 2 — From another Android phone: Download the Find My Device app from the Google Play Store (it is free and made by Google). Sign in with your Google account. Your phone will appear in the list of devices.

What to do if the phone does not appear on the map

Find My and Find My Device can only show a location if the phone is powered on and has an internet connection (Wi-Fi or cellular data). If the phone appears offline, both services will show you the last location recorded before it went offline. Check that location — it may be somewhere you recently visited. Keep checking back; if someone turns the phone on, the location will update.

If you believe the phone was stolen, do not try to retrieve it yourself. File a report with your local police department and give them the last known location from Find My or Find My Device. Also contact your wireless carrier to report the phone stolen so they can flag the device ID.

After you get a new phone

If your phone is lost for good, use the remote erase option to protect your personal data before you set up a new device. When you get a new phone, signing in to your Apple ID or Google account will restore your contacts, photos (if backed up), and apps. Always set up Find My or Find My Device on the new phone right away.
