No SIM trays. No paperclips. No "find a kiosk after baggage claim." Just a QR code, your phone's settings, and you're online — usually in under two minutes.
We've watched thousands of travelers do this on the airport bus. It's faster than ordering a coffee. Here's the whole thing.
You can install the eSIM at home over WiFi, then toggle it on when you land. That way you're online the second airplane mode comes off.
Search for your country (or pick a regional bundle if you're hitting several). Every country page shows local carrier names, speeds and per-GB price up front.
eSIMs run from 1 GB to unlimited. Most travelers buy 5 GB for a city break, 10–20 GB for a week, or unlimited for a month.
Apple Pay, Google Pay, card or Revolut Pay. The QR code lands in your inbox before the page even reloads.
iPhone: Settings → Cellular → Add eSIM → Use QR Code.
Android: Settings → Network & internet → Mobile network → + → "Don't have a SIM?" → scan.
Takes about 40 seconds.
The eSIM activates as soon as it sees a partner network. Make it your data line, keep your home SIM as the calling line — and your bank's 2FA still hits your normal number.
An eSIM is a digital SIM card built into modern phones. There's nothing physical to carry, lose, or hand to a stranger at a SIM kiosk in a third language. You can hold up to 8 of them on most iPhones — install one for every trip and switch with a tap.
