How to install an eSIM: 4 steps

1Check your phone

Your smartphone must support eSIM and be carrier-unlocked.

2Buy a plan

Pay by card — the QR code arrives by email within 1–2 minutes.

3Install before departure

Scan the QR on Wi‑Fi: Settings → Cellular → Add eSIM.

4Turn it on upon arrival

Frequently asked questions

Should I buy the eSIM in advance?

Yes — install it at home over Wi‑Fi, so on arrival you only need to switch on mobile data.

Will I keep my regular number?

Yes. The eSIM works alongside your main SIM: calls and SMS reach your number while data goes through the eSIM without roaming.

What if I run out of data?

Top-up plans (marked in the table) let you buy more data in the app. One-time plans require purchasing a new package.

Which phones support eSIM?

iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+ and most flagships released after 2020. The phone must be carrier-unlocked.
