Uber Pass is a membership that features benefits, including savings on rides and Uber Eats. You'll be able to subscribe by opening the menu in your Uber app.
Subscribing Uber Pass and Eats Pass at the same time is not available. You can only change your pass subscription once the current subscription expired, and note that you must have the latest version of the app to purchase.
Please note that subscriptions renew automatically, unless you cancel it 24 hours prior to the renewal date, and the fee charged every month is non-refundable once charged to you.
