The pass is available to all monthly contract Three customers, and when arriving in your European destination simply turn on your phone and you’ll automatically receive a text message with a link to http://mobile.three.co.uk/europass where you can go and activate the bundle. The £5 is valid until midnight (GMT) on the day you purchase it. Needless to say tethering is not included.
A weeks holidays could add up to £40 which isn’t bad if do a lot of social networking and email checking whilst away, but for occasional users you would probably be better off with a cheaper capped 10Mb or 25Mb bundle.
The opt-in bundle overrides the maximum roaming tariff of £43 so go over a week and you’d be worse off than just using PAYG.
