Does Dexcom G7 require a new receiver, or can I use existing Dexcom G6 receiver?
Dexcom G6 receivers are not compatible with Dexcom G7 sensors. Dexcom G7 features a redesigned optional receiver that is smaller with a more vibrant, easier-to-read display.
Dexcom G7 is also compatible with the latest smartphones if you'd prefer to use your phone. Check compatibility.
