Before you buy: key facts
- Data only. No local phone number, standard calls or SMS. Keep your US line on for calls and texts if you need them; charges on that line depend on your own carrier.
- When the plan starts. Your plan's validity starts when you first use it in a covered destination, not when you install it. Install on Wi-Fi before you fly.
- On arrival. Turn on data roaming for the travel eSIM and choose it for mobile data.
- Price. US dollars, paid once by card through Stripe. Not a subscription.
- Delivery. QR code by email after payment, with install steps.
- Refunds. For a change of mind, request a refund if the eSIM has not been installed. Refund policy.

United Kingdom eSIM questions
Does the United Kingdom eSIM include an UK phone number?
No. The plan is data-only: no UK phone number, standard calls or SMS. Use internet calling and messaging apps, and keep your US line switched on if you need its number for calls and texts; charges on that line depend on your own carrier.
How does it compare with a carrier day pass in the United Kingdom?
Verizon lists TravelPass at US$12 a day in the United Kingdom, and AT&T lists International Day Pass at US$12 a day on land (both checked October 31, 2026). A Telroo eSIM is paid once for the plan's validity. Multiply your carrier's daily fee by the days you will use it and compare that with the plan price above.
