The Dexcom G7 Geofence

The G7 app is geofenced, so if you’re traveling outside of your home country and your phone is lost, stolen, broken or goes for a swim, or the app fails, you may not be able to easily reinstall the G7 app. This restriction has nothing to do with your particular home country.  It affects every country.

Pro Tips:

  1. Bring a computer so that you can use a GPS Changer and VPN.
  2. Bring some G6, One or One+ sensors and a transmitter in your travel bag, extra test strips, your controller (and a charging cord) if you have one. You can manually enter BG into Loop or Apple Health.
  3. Turn-off auto update on the G7 app before leaving home. If you update, uninstall or try to reinstall the app while outside of your home country, you will lose the app until you return home.

Once you receive the “Country of residence issue” alert, you will most likely need to delete the G7 app and reinstall it by following the steps below.  You will need a computer and internet.
