About
One eSIM is prepaid mobile data for travellers. Pick a destination, pay by card and get an eSIM you install before you fly. When you land, switch it on and you are online, with your own number and SIM left exactly as they were.
WHERE IT WORKS
• 200+ destinations: single countries, regions such as Europe or South East Asia, and a global plan for trips with many stops.
• Most plans run on 5G, and every plan names the networks it uses before you pay.
PICK THE PLAN THAT FITS
• Daily unlimited plans: a full-speed allowance every day, then a slower fair-use speed until the next day.
• Fixed data plans: one amount for the whole trip, from a few days to a month.
• Most plans can be topped up from the app before they expire.
INSTALL IN A MINUTE
• On iPhone with iOS 17.4 or later, install with one tap.
• Or scan the QR code, or enter the details by hand, with copy buttons for each.
• Install at home on Wi-Fi. On nearly every plan, the days only start when the eSIM first connects abroad, so installing early costs nothing.
YOUR TRIP IN ONE PLACE
• See data left and expiry for each eSIM.
• Every order and receipt, and the QR code emailed again if you need it.
• Step-by-step help for no signal or no data, and a check for whether your phone supports eSIM.
CLEAR PRICES
• Prices in US dollars with taxes included. No activation fee, no subscription.
• A full refund for any eSIM you have not installed.
Sign in with your email, Apple or Google; no password needed.
One eSIM is data only: it has no phone number, calls or texts. Your phone must support eSIM and be carrier-unlocked.

Clearer plans. • Plans have simple names, the same in the app, on the website and in your emails. • Unlimited plans show exactly what you get: unlimited data, the first part of each day at high speed, then the fair use speed. • Plan cards show the same facts in the same place, including whether a plan can be topped up.
