Hello.
If you're only using the data while the Data Passport is active, then you won't be charged a daily fee on top for the data used.
It's important to remember though that the daily charge is applied whenever any allowances are used, not just data. If that happens, you would be charged for daily roaming as well. It's also worth mentioning that your daily roaming charge becomes applicable again at midnight in the destination you are at, but the data passport expires at midnight UK time, so you'll want to make sure to keep an eye on the expire time for the Passport whenever you're using the data.
Pete.
