If you’ve lost your mobile smartphone or tablet, or if your device is stolen, you can often find its location by going to a dedicated website on your computer. But before your device can be located, your mobile device needs to be setup to allow it to be located. Now is the time to check and make sure your device is setup – before your phone gets lost or stolen.
For an iOS device such as an iPhone or iPad, go into Settings > iCloud, and make sure “Find My iPhone” is on. Once setup on your device you can go to http://iCloud.com in your computer web browser, sign into your iCloud account and choose Find my iPhone.
For an Android device with software version 4.1 or above, follow the instructions here to turn on Android Device Manager on your device. Then go to https://www.google.com/android/devicemanager in your computer web browser, sign into your Google account and follow the prompts.
If you have a Windows Phone, follow these instructions.
