What if I don't have phone service or WiFi?

WiFi, or a mobile data connection, is only required for initial app setup (downloading/installing the app, creating an account or signing in) and for sharing your glucose information with your healthcare team or with other connected apps. The app* does not require a WiFi or mobile data connection to scan your sensor or to record your current glucose readings. During periods when your phone is operating in a disconnected state, your data will only be uploaded to LibreView^† after a WiFi or mobile data connection is restored.

^{† The LibreView website is only compatible with certain operating systems and browsers. Please check  www.libreview.com   for additional information.}

^{* The FreeStyle LibreLink app and the FreeStyle Libre reader have similar but not identical features. A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the FreeStyle LibreLink app or when symptoms do not match the app readings. The FreeStyle Libre sensor communicates with the FreeStyle Libre reader that started it or the FreeStyle LibreLink app that started it. A sensor started by the FreeStyle Libre reader will also communicate with the FreeStyle LibreLink app. The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check the Compatibility Guide (PDF 69 kB) for more information about device compatibility before using the app. Use of FreeStyle LibreLink requires registration with LibreView.}
