Pay Monthly Add-on costs.

About Add-on unit costs.

Below you can see the exact cost of each unit within your Add-on allowance. A unit means either one minute of calls, one text or one megabyte of data.

If any of your allowances are all-you-can-eat, for the purposes of calculating a price per unit for you, we treat them as being units entitling you to either 3000 minutes, 5000 texts or 25GB of data, so that we can show a unit cost.

If you’re not sure what Add-ons are, or want to know how to buy an Add-on, check out Buying data & Add-ons.
