Airtag beyond Bluetooth range

Your AirTag sends out a secure Bluetooth signal that can be detected by nearby devices in the Find My network. These devices send the location of your AirTag to iCloud — then you can go to the Find My app and see it on a map. The whole process is anonymous and encrypted to protect your privacy. And itʼs efficient, so thereʼs no need to worry about battery life or data usage.

What you need 

• An iPhone, iPad, or iPod touch running iOS 14.5 or iPadOS 14.5 or later. 
• Find My turned on.
• Bluetooth turned on.
• A strong Wi-Fi or cellular connection.
• Location Services turned on: Go to Settings > Privacy > Location Services.
• To be able to use Precision Finding and to see the most accurate location for your AirTag, turn on Location Access for Find My. Go to Settings > Privacy > Location Services, then scroll down and tap Find My. Check While Using the App or While Using the App or Widgets, and turn on Precise Location.
