Unfortunately, we don't have any packages/add-ons for Roaming in USA.
Any usage would be chargeable at the Roaming rates found here: https://www.idmobile.co.uk/help-and-advice/international-and-roaming-charges
If you're on an older Takeaway plan, you'll have Roaming in USA for your minutes, texts to UK numbers and any data.
Takeaway plans are now legacy plans and not something we offer. Anyone still on one can use the features.
