Can I use the National Geographic App on multiple devices?
You can use your login to sign in to the National Geographic App on up to two devices at the same time, your app preferences and viewing history will also be visible across both devices. If you attempt to sign in on a third device, the first device will be logged out and show the message “Your Eligibility Could Not Be Verified. Please log in again”.
If your household has multiple eligible mobile phone services, each service will have its own login available to use on up to two devices at a time.
If you log in with My Account, you will only be able to log in to two concurrent devices, even if you have multiple Mobile Broadband and Fetch with Optus services attached to your account.
