Hi @JamesN22, thanks for your post here in the community.
Unfortunately, we do not offer any bundles for the USA - we do offer free roaming across the EU if this helps for any future trips you have planned but I appreciate not your upcoming one.
I'd recommend if you have an unlocked device, to potentially purchase a local SIM where you can get data allowances, popping this into your handset and putting your Virgin Mobile SIM back in when you return!
I hope this helps.
Many thanks
