how much data does a 1 hour skype video call use?
Video calls, or video-chat, are the most commonly used of Skype's core features. However, video calls use more data than voice only calls, so it's important to know the difference. Video calls use 270 MB per hour, which is good for 4 hours on 1 GB. On a 50 GB plan, you can video-chat for 132 hours.
