Getting started

Download the t:connect mobile app on your phone and then pair the app with your t:slim X2 insulin pump. Here are the steps to follow:




Visit Google Play or the App Store, search for “Tandem Diabetes” and select “t:connect mobile” from the results.




Unlock the pump, tap OPTIONS, Device Settings, and then select Bluetooth® Settings. Tap the toggle to turn on the Mobile Connection and enable Bluetooth.

If you don't see Bluetooth Settings, you can visit the Customer Portal to update your pump to the latest software (you may need a prescription and training).




Use your t:connect web application username and password (or create a login and password in the t:connect mobile app).

We strongly suggest you upload your pump data to the t:connect web application via a USB cable before starting the next pairing step.




Pair Insulin Pump to Mobile App


Follow the prompts to pair your t:slim X2 insulin pump with your phone. For detailed pairing instructions, view our Quick Reference guide or watch the above video. Only one device can be paired with the t:connect mobile app at a time.

After you have synced your pump to the app, the data will upload to your t:connect account. This can take minutes, hours or days depending on when you last uploaded and how much data is stored on your pump.

* The information on the t:connect mobile app display may not be identical to the current status of your pump. Wireless uploads from the t:connect mobile app to the cloud-based t:connect web application require a compatible phone and an internet or wireless data connection. Uploads to the t:connect web application do not take place in real time and should not be relied upon by healthcare providers or caregivers for remote patient monitoring. Standard carrier data rates may apply.
† You cannot dismiss alerts and alarms from the app and must do so on the pump itself, but once an alert or alarm has been dismissed on the pump it will immediately disappear from the mobile app.
