Skype data usage The data used by a Skype video call depends on what devices are involved at either end, and on the 'bandwidth' that is available (i.e. the data transfer rate, or speed of your internet service). Video calls between two mobile devices using Skype over the cellular network apparently uses about 3.75 MB of data every minute. If you are on a faster home internet service and making a HD video call, you may use up to about 22.5MB per minute. The below table shows some approximations of the number of Megabytes used for some typical types of Skype calls - those that don't include videos and those that do.
