Hot on the heels of Apple's AirTag announcement, T-Mobile is launching the SyncUp Tracker, which uses LTE and GPS instead of Bluetooth or ultra-wideband (UWB) for locating lost items. Like AirTag and Tile, customers can attach the SyncUp Tracker to items such as luggage, keys, bikes, wallets, or pets' collars. If users lose the item, they can attempt to locate it through a corresponding iOS app. T-Mobile's $60 lost-item tracker works with the SyncUp app, which will be available for free on the App Store. While Apple's AirTag doesn't have a built-in cellular connection, it can tap into Apple's Find My network when the tracker is out of reach of the user's iPhone. This method calls upon any nearby Apple devices to transmit the AirTag's location data.
