Yes. Using the app makes uploading your pump data to the t:connect web application easier than ever before. When your pump is paired with the t:connect mobile app, the app will securely and automatically upload your data into your t:connect account, typically once per hour, whenever your phone is connected to Wi-Fi or you allow cellular data usage.
Tandem handles issues with the connection between your Dexcom transmitter and t:slim X2 pump, questions about calibration, the “---” display, and sensor failures after the 2-hour warmup period. To report a sensor failure after the 2-hour warmup period, visit tandemdiabetes.com/G6Form
For all other CGM issues, including sensor failures during the 2-hour warmup, “no restarts” alert, or physical problems with your sensor or transmitter, such as bleeding, bruising, skin reaction, adhesive issues, applicator issues, or broken wires, you should contact Dexcom using one of the options at dexcom.com/contact.
