EU Roaming Pass, where do you buy?

Garenth_2680881  SmartyTrousers  Please see Price guide p17:-

SMARTY’s EU Roaming Data Passes give you access to your whole plan data
allowance for the period of time you choose, instead of being restricted to the
standard monthly 12GB EU roaming fair usage cap. See page 12 for information on
“Fair usage policies” and page 18 for details of “Roaming”.
EU Roaming Data Passes are available for 1 day and 3 days (where a day is
determined as 24 hours from time of activation) and, if you are on a plan with
over 12GB, gives you access to the rest of your plan whilst in the EU,
for that period. When the pass expires, you will return to your normal data plan.
Add-on price includes VAT.

As I do not have more than 12Gb on my plan, I do not expect to see the option to buy the above.
