Allow capacity per stream
HD streams often require roughly 5–10 Mbps, while 4K can require 15–25 Mbps or more depending on the provider. Multiple streams add together.
Stability prevents buffering
Streaming apps can buffer data, so latency is less critical than gaming, but sustained throughput and reliable Wi-Fi remain important.
Plan for the whole household
Leave spare capacity for calls, updates and other devices rather than choosing a package that only just matches the theoretical requirement.
