Which USA eSIM Type Should You Choose?
Choose Unlimited USA for straightforward travel data
Select a dedicated Unlimited USA eSIM when your priority is data during a trip that lasts between 1 and 30 days and you do not require standard mobile calls or SMS.
Choose Three Mobile for UK service plus USA roaming
Select Three Mobile when you also need a UK plan and UK telephone number. Match the USA portion of your trip to the included roaming allowance rather than the larger UK allowance.
Choose Orange Holiday World for multi-country travel
Select Orange Holiday World when your journey covers the USA and other supported destinations and you prefer one international product for the wider itinerary.

- Complete your order: Use an email address you can access while travelling.

USA eSIM Tips for 2026
- Keep your original SIM active only if you need it for calls or security messages, and disable its data roaming if you want to avoid home-network charges.
- Save the installation details securely before departure.
- Network availability and speed vary by location, building, congestion and compatible frequency bands.
- Do not delete an installed eSIM unless the supplied instructions confirm that it can be reinstalled.
- For Three Mobile and Orange, distinguish the product’s home-market allowance from the separate allowance available while roaming in the USA.
