* 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.
† Additional feature updates are not currently available for the t:slim X2 insulin pump with Control-IQ technology and are subject to regulatory approvals. Future updates for some or all of Tandem's products may not be developed and may not be offered everywhere. Software updates are only available to customers who are in warranty at the time they update their pump, and may require a prescription and additional training. Charges may apply. Tandem may discontinue select software and features over time at its discretion.
