Data transfer is rounded to the nearest KB on a daily basis and charges are rounded up to the nearest 1p. Minimum data charge is 1p. Each additional MB is charged as per the table above, billed pro rata in units of KB. All prices shown are for payment by Direct Debit - a different rate may apply if paying by another method.

This may include charges for resent data, and additional information required to control data flow. To minimise costs - and maximise the speed of data transmission - the total amount of data carried over the network is substantially reduced by intelligent data compression.
