How much data does Netflix use, and how can travelers reduce it?
Netflix can use very little data or burn through a travel plan quickly depending on video quality, downloads, autoplay, and whether you stream on mobile data or Wi-Fi.
Quick answer
Netflix data use depends mostly on quality
Low-quality streaming can fit into a small travel eSIM, while HD and 4K can use a large amount of data in one evening. The safest travel setup is to download shows on hotel Wi-Fi, disable autoplay previews, and set Netflix to Wi-Fi only unless you bought a large plan.
