    Tell us where you’re flying

    Type the country, city, or IATA code. We pull live prices from 14 carriers per destination and rank them by price-per-GB. The cheapest wins by default.

    • 200+ countries · 14 carriers each
    • Filters by your trip length and the GB you’ll actually use
    • Always shows $/GB so you spot rip-off plans instantly
  2. 02Step 02 · 30 sec

    Pay. No account required.

    Card, Apple Pay, Google Pay. We don’t store your card. We don’t make you make an account. The receipt and install QR land in your inbox before the CVC finishes typing.

    • 256-bit · PCI-DSS · we don’t store card details
    • Guest checkout — make an account later if you want one
    • Wallet credit auto-applies (referral + price-match wins)
  3. 03Step 03 · 30 sec

    Scan the QR. Install the eSIM.

    Open your phone Camera, point at the QR we email you. Settings handles the rest. Don’t activate yet — that part happens the moment you land.

    • Works on every iPhone XS+ and Android with eSIM
    • Set esimple as data-only — keep your home SIM for calls
    • Full install guide for both platforms
  4. 04Step 04 · On landing

    Land. Connect.

    Your data plan only starts when your phone catches the destination network — so the clock doesn’t tick during a flight delay. You walk off the jet bridge with full bars.

    • 30/60/90-day windows — never just hours like airport SIM kiosks
    • Top up from your account if you run low
    • Refund if it doesn’t activate, no questions

Pre-boarding questions.

Need more? See the help center.
Will my phone work?

Any iPhone XS or newer, plus most Android phones from 2020+. We auto-detect compatibility during checkout. If your phone doesn’t support eSIM, we’ll tell you before you pay.

Can I buy before I fly?

Yes — buy and install at home. The plan only activates when it sees the destination network, so the clock starts on landing, not on purchase.

What if I run out of data?

Top up from your account in 3 taps. Same $/GB as the original plan, no upcharge for being abroad. Or buy a fresh plan if you’ve changed countries.

Will I still get calls?

Yes. Set esimple as your data-only line. Your home SIM keeps handling calls and SMS — including 2FA codes — over Wi-Fi or voice-roaming.

What if it doesn’t activate?

Full refund, no questions. We auto-detect activation failures in the first 4 hours and email you a refund or replacement — your call.

Multiple countries on one trip?

Use a regional bundle for whole continents on one SIM, or stack country plans. Both work out cheaper than roaming.
