Which Tandem Pumps Support Dexcom G7?

Before you start, ensure your pump is compatible. As of April 2025, the following Tandem pumps support Dexcom G7 integration:

If you’re using an older model like the t:slim or t:flex, you may need to upgrade your device by purchasing on CGM Monitors. Check with Tandem Diabetes Care to confirm eligibility for using Dexcom G7 with Tandem insulin pump.

Steps to Update Your Tandem Pump to Dexcom G7

Updating your Tandem pump to Dexcom G7 is straightforward, and for in-warranty users, it’s free! Here’s your Tandem pump Dexcom G7 user guide to get started:

1. Verify Your Pump’s Software Version

First, check your pump’s current software. For the Tandem X2 insulin pump Dexcom G7 setup, you need version 7.7 or later. On the Tandem Mobi, the latest software already supports this integration. To find your version:

• On t:slim X2: Go to Options > My Pump > Pump Info.
• On Tandem Mobi: Open the t:connect mobile app, tap Settings > Pump > Pump Info.

If your software is outdated, proceed to the next step for the Tandem pump Dexcom G7 sensor update.

2. Log In to Your Tandem Account

Visit the Tandem Diabetes Care website and log into your customer portal. If you don’t have an account, create one—it’s quick and easy. This is where you’ll access the update process for Dexcom G7 setup with Tandem pump.

3. Complete the Online Training

Tandem requires a short online training session (about 30 minutes) for software updates. This ensures you understand how to sync Dexcom G7 with Tandem X2 or Mobi effectively. Once completed, you’ll receive a unique update code.

4. Download the Tandem Device Updater

Connect your pump to a computer via USB and download the Tandem Device Updater software from the website. Enter your training code, and follow the on-screen instructions to update your Tandem pump to Dexcom G7 Compatibility. The process takes about 10-15 minutes.

5. Pair Your Dexcom G7

After the update, it’s time for Dexcom G7 pairing with Tandem pump:

• Insert a new G7 sensor (it warms up in just 30 minutes!).
• On your pump, go to Tandem X2 Dexcom G7 settings via Settings > CGM > Pair New Device.
• Enter the sensor’s transmitter ID when prompted.

Your Tandem pump and Dexcom G7 should now sync via Bluetooth, delivering real-time glucose data to optimize insulin delivery.
