Hi ​@AlexR13, 

We'd be happy to clarify this for you. The Netherlands is one of iD Mobile's inclusive Roam Free destinations, so you can use your UK allowance there, subject to the terms and allowance applicable to your plan.

If you can't see any additional charges on your billing page, this doesn't necessarily mean there's an issue. Your usage can continue to be taken from your included roaming allowance without appearing as an additional charge.

However, we'd strongly recommend setting your Bill Cap to £0 while you're abroad. This will help prevent unexpected out-of-plan charges if your handset connects to a roaming network that isn't one of iD Mobile's supported partner networks.

As long as you're connected to an appropriate supported network and remain within the roaming allowance applicable to your plan, you can continue using your mobile data in the Netherlands.

Have a great time in the Netherlands, and if you experience any issues with your roaming service, please contact us via Live Chat and we'll be happy to help.
