Hello Bonbon17, we know the importance of being able to enjoy Disney+ and we're here to help. You get one Disney+ promotion per account. This means that only one line can register for it. At the moment, 10 unique compatible devices can be used with that subscription. Each subscription can have up to 4 devices streaming at the same time. You can learn more about our Disney+ promotion at http://spr.ly/66081RUzG. Does this information help?
