You do not need to have a network connection to find a nearby Chipolo using the Bluetooth-enabled search capability of the Chipolo app. Your app will also remember the last known location when that specific phone was in contact with one of your Chipolos. You will need a network connection to get Chipolo location data that may have come in through someone in the community finding your Chipolo. You also need a network connection (cell data or WiFi) to register in the Chipolo app, sign in to the app and to activate your Chipolos. Once signed in internet access is not required for finding your Chipolo via the app.
