I’m an existing customer. Can I upgrade to Dexcom G6?

As the battery life of a Dexcom G5 Transmitter is 3 months (90 days), smart device users are free to switch to Dexcom G6 once their Dexcom G5 Transmitter nears the end of its battery life and they have used their existing supply of Dexcom G5 Sensors. Customers using a Dexcom G5 Receiver to display glucose data will require the purchase of the new Dexcom G6 Receiver if they wish to switch. The Dexcom G5 Receiver is not compatible with Dexcom G6.
