When you start a new plan the data is proratered so you don't get the full amount til the second month, not sure if this happens when changing a plan mid month? Or if you change from, for example, 10 to 40 gig and you have used the 10 gig already if you only then get 30 gig for that month ?&nbsp;</P> Wed, 26 Nov 2025 07:03:43 GMT https://helpforum.sky.com/t5/Sky-Mobile/Excessive-data-use-in-short-period/m-p/5151809#M276375 63johnw 2025-11-26T07:03:43Z
