Do you mean the Euro Data Pass? The EE website is a mess when it comes to finding out information, but isn't it £4 for normal plans and £3 for EE Extra plans? As such, I'd be very disappointed to learn you can't have it on the discounted deal, as it's still advertised as EE Extra.
I've tried sending the code to 150 and not had any response positive or negative yet. The website says it could take 24 hours, but surely you'd get some acknowledgement?!
I do wish EE would just let you use your allowance, and not speed cap after a rather pathetic 100MB. Vodafone is leagues ahead on this.
EDIT: Bad news, it says it isn't available on this plan.

This better be fixed as you can't sell a plan with a discount and then change the conditions surely? If this plan hasn't got the same features, it's not the same plan!
PS. Who told you it isn't available? It wasn't mentioned in anything I saw online and wasn't mentioned to me in store.
