Top FAQs

  • Yes, you can choose which glucose notifications you receive for each Sharer. Changes to settings in the Follow app don’t affect the Sharer’s CGM settings.

    If your Sharer is sharing their trend graph, go to their graph and then tap the gear icon. If your Sharer isn’t sharing their graph, tap them in the list to change their notification settings.

    The Sharer decides if you can view their trend graph or not.

  • Yes, you’ll still receive Follow notifications.

  • No. Your Follow notifications will only vibrate.

    LBL017267 Rev001
  • There are several reasons you may not receive expected notifications.

    In your Follow app:

    Check your Sharer’s glucose notifications. Turn on the ones you want.

    Check each notification’s delay setting. If a delay is set, you’re only notified if the condition lasts longer than the delay.

    Check your Sharer’s status. If you see No Data, Disconnected, Not Sharing, or Removed by Sharer you won’t receive notifications. Ask your Sharer if you have questions.

    Other issues:

    • Check that you have an Internet connection.
    • Check your smart device settings.
    • Open settings, then notifications. Find Follow in the app list and turn on notifications.
    • Dexcom’s server may be down.

    If you continue to experience issues, contact Dexcom Technical Support at 1-844-607-8398 24 hours a day, 7 days a week.

  • Allow notifications from Follow in your smart device settings.

    1. Go to your smart device settings.

    2. Go to notifications.

    3. Find Follow in the app list and turn on notifications.

    Allowing notifications to show on your lock screen and keeping your volume loud help ensure you don’t miss notifications.

  • Remotely monitor a Dexcom CGM user’s glucose with the Dexcom Follow app.

    • Once a Sharer’s invitation is accepted, the Follower can see:
    • Sharer’s glucose reading
    • Sharer’s trend arrow showing their glucose speed and direction Glucose notifications of changes, like a Low or High

    Both the Sharer’s and Follower’s smart devices must have Internet. For a list of smart devices compatible with Dexcom apps, see dexcom.com/compatibility.

  • We recommend checking the Dexcom compatibility chart before installing a new iOS or Android OS version on your smart device. Dexcom tests all its apps on new OS versions after the OS is released. It may take several days or more to complete testing and, if necessary, update the Dexcom app to be fully compatible with a new OS version.
