I’m a former Smithsonian Earth subscriber. How do I use a promo code to sign up for Smithsonian Channel Plus?

If you were a former Smithsonian Earth subscriber and would like to sign up for Smithsonian Channel Plus with a promo code, follow the instructions below: 

  1. Sign in with your Smithsonian Earth email and password. We recently increased the password security requirement, so if you are prompted to create a new password, follow the instructions on the screen. If you forgot your Smithsonian Earth password, reset your password.
  2. Click the START FREE TRIAL button on top of the screen. If you are on a mobile device, tap the menu button in the top-right to see this option.
  3. Follow the instructions on the screen. Because it’s been a while since we’ve seen you, you will need to re-enter your payment information.
  4. Enter your code on the Payment page under PROMO CODE to lock in your promotional monthly rate.
