没有什么比丢失手机或被盗更糟糕的了。在本文中，我们将介绍您需要启用哪些项目才能找到已关闭的丢失手机。此外，手机可能需要电源和互联网连接。 

对于所有这些方法，您需要在手机丢失之前启用恢复功能。如果它已经丢失，您仍然可以找到它^{(you may still be able to track it down)}。设置一个严格的锁屏密码，这样小偷就会发现更难重置手机或让你退出任何重要帐户。 

但是，如果有人将您的手机恢复出厂设置，您就不太可能取回它。 

谷歌查找我的设备

您可以使用Google 的“查找我的设备^{(Google’s Find My Device)}”查找任何具有互联网连接的Android手机，并且您的手机已登录您的^(Android)Google帐户。当手机丢失时，可以通过Play 商店^{(Play Store)}免费 提供的Google 查找我的设备应用程序或通过网络找到它。^{(Google Find My Device App)}

通过^(Via)IMEI 号码^{(IMEI Number)}跟踪您的手机

IMEI代表国际移动设备标识^{(International Mobile Equipment Identity)}，是每个 iPhone 独有的 15 位数字。即使窃贼安装了新的SIM 卡^(SIM)或将您的手机恢复出厂设置，IMEI号码也独立于SIM卡工作。^(SIM)在手机包装盒上的条形码上方或在“设置”^(Settings) > “通用^(General)” > “关于^(About)”中找到IMEI号码。  

您或警方可以使用其IMEI号码跟踪或阻止您丢失的手机。您应该为被盗手机获取警方报告，以通过网络提供商阻止您的 iPhone。规则可能因提供商和国家/地区而异。

但是，高级犯罪分子可以使用一些可以更改或阻止IMEI号码的设备。 

当局可以与网络提供商协调，通过IMEI跟踪电话。但是，同样，它要求手机连接到网络。网上有很多IMEI追踪器诈骗需要付款，所以远离他们。 

第三方跟踪应用

一些受信任且安全的应用程序旨在提高您的设备安全性，并在设备丢失时找到它。

How To Ensure You Can Locate Your Phone Even If Lost or Turned Off

There’s nothing worse than losing уour phone or having it stolen. Іn this article, we’ll cover the itemѕ you need tо enable in order to locatе a lost cеll phone that is turned off. In addition, the phone may need power and an internet cоnnection. 

For all these methods, you need to enable the recovery features before the phone is lost. If it’s already lost, you may still be able to track it down. Set a tough lock screen passcode so that a thief will find it harder to reset the phone or sign you out of any crucial accounts. 

However, if someone factory resets your phone, it’s unlikely that you will ever retrieve it. 

Google Find My Device

You can use Google’s Find My Device to find any Android phone provided it has an internet connection, and your phone is signed into your Google account. When the phone is lost, it can be located via the Google Find My Device App available on the Play Store free of charge or via the web. 

Enable Find My Device: 

1. Open Settings. 
2. Scroll down and select Google. 

1. Select Find My Device. If it’s turned off, turn it on. 

1. Ensure that you permit it to access your location. 

To find your phone using Google Find My Device on another device (phone or computer): 

1. Open the Play Store, search Find My Device, and install the app. 
2. Open Google Find My Device. 
3. Sign in to your Google account.
4. If the lost device is signed in to your Google account, the app will display its location. 
5. Select Secure Device and provide a lock screen message and phone number so that anyone in possession of your phone can contact you. 

Tip: You can also use Find My Device to erase data from your lost phone remotely.

Google Timeline

If your device has run out of power, you may still be able to locate your lost cell phone that’s turned off via Google Timeline. For this to work, ensure that the following are enabled before the device is lost : 

1. Sign in to your Google account. 
2. Internet access should stay enabled. 
3. Location Reporting and Location History is on. 

To Turn on Location Reporting: 

1. Open Settings > Apps. 
2. Find and select Maps. 

1. Select Permissions and ensure that Location is enabled. 

To Turn on Location History: 

1. Open Maps. 
2. Select your user icon at the top-right of the window. 
3. Select Settings.

1. Select Google location settings.

1. Scroll down and check Google Location History. If it’s not turned on, select it and choose your Google account.

1. Scroll down and check Location History to turn it on. 

If you lose your phone, you will now be able to see its last known location. Simply sign in to your Google account on another device, open Maps, and select Your Timeline.

If the phone is still on, you’ll be able to see its current location. Otherwise, you’ll see its location before losing power or being signed out of your Google account. 

Samsung Find My Mobile

Samsung has its own Find My Mobile service, which you must enable before the device is lost. To enable this: 

1. Open Settings > Biometrics & Security. 

1. Scroll down and select Find My Mobile. 
2. Turn this On if it’s off, and ensure that your Samsung account is correct. If needed, sign in to your Samsung account.  

1. Turn on Send last location and Offline finding.

Note: Send last location will upload the phone’s last location before it runs out of battery. If the phone has power, Offline finding allows other nearby Samsung devices to discover your phone even if it’s not connected to the internet. You can also enable Encrypt offline location to protect your location data. 

To find your phone, head to the Samsung Find my mobile website. Sign in to your Samsung account and select Locate my device in the sidebar. If the device is turned on and connected to the internet, you will see its location. You will also be able to lock your device or wipe its data from this website. 

Find My iPhone

An iPhone will display its current location or the last known location before you turned it off. Then, using another device, like an iPad or iPhone, you can see its last location before you lost it. 

To Turn on Find My iPhone: 

1. Open Settings. 
2. Tap your name. 

1. Select Find My > Find My iPhone and turn on Find My iPhone, Find My network and Send Last Location. 

Note: Send Last Location will save the last location of your iPhone before it loses power. The Find My network will allow other nearby iOS users to locate your iPhone even if it’s turned off. 

To find your iPhone, simply access the Find My app from another iOS device or sign in to iCloud.com/Find. Sign in to the app/website, select Devices, then select your iPhone from the list. 

You can turn on Notify When Found to send you a notification when it’s next turned on. You can also enable Lost Mode, which will lock your iPhone and allow you to display a custom message and contact number to whoever finds your phone. 

Tracking Your Phone Via the IMEI Number

IMEI stands for International Mobile Equipment Identity and is a 15 digit number unique to every iPhone. The IMEI number works independently of the SIM card even if the thief installs a new SIM or factory resets your phone. Find the IMEI number above the barcode on the phone’s packing box or in Settings > General > About.  

You or the police could track or block your lost phone with its IMEI number. You should procure a police report for your stolen phone to block your iPhone through the network provider. Rules may differ by provider and country.

However, advanced criminals have access to some devices that can alter or block the IMEI number. 

Authorities can track a phone via the IMEI in coordination with the network provider. But, again, it requires that the phone is connected to a network. There are many IMEI tracker scams online which will demand payment, so stay away from them. 

Third-Party Tracking Apps

Some trusted and safe apps are designed to increase your device security and find it if it gets lost. 

Avast Antivirus

Avast Antivirus is one of the biggest names in antivirus software, and now it supports recovering lost devices, too. To activate this function: 

1. Open Google Play Store or Apple Store and search Avast Antivirus. 
2. Select it from the list, select Install. 
3. Upon completing installation, select Open. 
4. Go through the setup process, allow it to update, provide permissions, then create an account.
5. Select Use basic security unless you want the paid version. 
6. Select Continue as free.
7. Select the three horizontal lines at the top-left of the screen.

1. Select Anti-Theft.

1. Select Set Up Now. 
2. Follow the instructions to set up your Anti-Theft account. You will need to set up a pin code, grant several permissions, and connect your device to your Avast Account. 

1. Finally, sign in to your Avast Account when prompted. 

The free version of this app allows you to lock your device and sound a siren remotely. With the paid version, you can also use a camera trap to take a photo from your phone’s selfie camera. The paid version also enables your last known location. The main benefit of Avast Antivirus is that you have multiple security measures in one place. 

To find a lost phone and input remote commands, head to your Avast Account.
