Find My Phone

Find my Phone or similar is the name given by various manufacturers to software and a service for smartphones, whereby a registered user can find the approximate location of the phone if switched on, over the Internet, or by the phone sending e-mail or SMS text messages. This helps to locate lost or stolen phones.[1][2]

Apple offers a free service called Find My for iPhones running iOS. Microsoft's My Windows Phone once offered a similar service for phones running Windows Phone. Similarly, Google offers Find My Device for phones running Android.[3]

Some of these applications may have limitations which can be checked before installing, such as only working in some countries, dependencies upon the phone's implementation of GPS, etc.[4] Similar paid or free apps are also available for all device platforms.

Similar applications are available for computers. Computers rarely have built-in GPS receivers or mobile telephone network connectivity, so these methods of location and signalling are not available. A computer connected to the Internet by a cabled connection gives its location as the location of the Internet Service Provider (ISP) it is connected to, usually a long distance away and not very useful, although the IP address may help. However, a WiFi-connected computer (typically a laptop computer) can find its approximate location by checking WiFi networks in range against a database, allowing approximate location to be determined and signalled over the Internet.[5]
