Upload speed

Meaning

Upload speed is how fast data travels from your device to the internet. Sending an email attachment, joining a video call, backing up photos to cloud storage, posting a video or running a home camera that stores footage online all use upload capacity. Many connections offer much lower upload than download, so people who mostly browse may never notice, while frequent uploaders and creators should check it separately. If a plan page lists only one number, ask what the upload figure is. See also: Download speed, Symmetrical speed, and the guide What Mbps Means: Download Speed, Upload Speed and Latency.
