Download Movies to Your iPhone
Another great way to save data on your iPhone is to download the movies and shows you want to watch in advance while you’re on Wi-Fi.
Using this method will allow you to watch any movie or show you want without consuming your cellular data. Likewise, you can also watch everything at the highest resolution possible.
To download content, you’ll need to open the streaming service you want and find the movie or show you wish you download. Then, find the downward pointing arrow or the download option.
Keep in mind that not every streaming service lets you download movies or shows. Some require a premium subscription, while others don’t allow downloads at all
Likewise, even if you can download content, not all movies or shows are available for download. Check your streaming service to make sure you can actually make use of this feature.
