Yes! You can easily access the Nick Jr. App if you are traveling within the U.S. by connecting to Wi-Fi or by using mobile data, like 3G, 4G, or LTE. If you are traveling outside the U.S., you won't be able to use the Nick Jr. App unless you are living on a U.S. military base. You'll just want to make sure you have a strong Internet connection for the best possible experience.
