The new 7.7 update brings the much-anticipated integration with the Dexcom G7 CGM.
  • 30-minute warm-up
  • 60% smaller
  • 12-hour grace period
  • All-in-one sensor and transmitter
  • The only waterproof CGM‡‡ - Feel confident in your glucose numbers even while bathing, showering, or swimming
  • Convenient sensor changes - The only CGM that connects to Tandem and has a 12-hour grace period, choose when to change your sensor

The t:slim X2 insulin pump is now compatible with the Dexcom G6 and Dexcom G7 continuous glucose monitoring (CGM) sensors.

‡‡ The Dexcom G7 sensor is waterproof and may be submerged under 2.4 meters of water for up to 24 hours


New Features to Control-IQ technology

Sensor Expiring Soon

Your pump tells you how much time you have left until your continuous glucose monitoring (CGM, sold separately) sensor session is complete. The Sensor Expiring Soon screen will now show at 24 hours remaining instead of at six hours remaining. It will also show at two hours remaining and 30 minutes remaining before your session ends.

Auto-off Alarm

Your pump can stop insulin delivery and alert you if there has been no interaction with the pump within a specified period of time. The default for this alarm is now preset to off. Updating your current pump will not change your existing setting and you can still set it anywhere between 5-24 hours, or off. If you are not using a CGM, we recommend keeping this Alert set to on.

Exercise Timer

You can now set a timer for a particular exercise duration so you do not have to remember when to stop the Activity when you are done exercising. You can set the timer between 30 minutes and eight hours.

Activity Transition

You no longer need to stop an active Activity before switching to a different Activity. For example, if Sleep is active, you can start Exercise simply by tapping Exercise. You do not need to manually stop the Sleep Activity before tapping Exercise.
