Internet Connection (Wi-Fi or Cellular Data)

Internet connection is required to see your Sharers' readings and get notifications. When there are no Wi-Fi networks available, turn on Cellular Data to connect to the Internet. If you disconnect from both Wi-Fi and Cellular Data, you won't see any readings, or get notifications.
If your phone or cellular service carrier doesn't support voice and data at the same time (VoLTE), you might disconnect from the Internet and delay notifications during phone calls.

  1. Go to phone Settings
  2. Turn on Wi-Fi or Cellular
  3. If VoLTE is supported, turn on VoLTE in Cellular Data options
