Dexcom sensors can be paired with one medical device (e.g., either a Dexcom receiver or a Tandem Diabetes Care insulin pump) and one non-medical device (e.g., smartphone or tablet) at the same time. For example, a Dexcom sensor can connect to your t:slim X2 insulin pump and your smartphone. However, you cannot connect a continuous glucose monitoring (CGM) sensor to both the insulin pump and the Dexcom receiver at the same time.
Your connected smartphone can have both the t:connect mobile app and Dexcom mobile app with the Dexcom Share feature operating at the same time.
Important Note About CGM Support
Dexcom and Tandem have agreed which system issues are best handled by each company, including which company is responsible for reporting those events to the appropriate regulatory authority. To help ensure that the required reporting takes place in a timely fashion, customers may need to contact Dexcom for some issues and Tandem for others. Learn which continuous glucose monitoring (CGM) issues are specific to the sensor or the insulin pump, and which company to contact.
