Frequently asked questions
What is an eSIM?
A 100% digital SIM card, already built into your phone. You scan a QR code and it's installed — your usual number stays active alongside it.
Is my phone compatible?
Most smartphones since 2018 (iPhone XR and up, Galaxy S20 and up, Pixel 3 and up…). We check your compatibility before any purchase — see the list of models.
When does the eSIM activate?
You install it before you leave and it activates automatically when you arrive in the country. Nothing to do at the airport.
How much data should I plan for?
Count ≈ 0.4 GB per day for maps, 0.6 GB for social media, 0.5 GB for sending photos and 1.2 GB if you watch video. For ten days of ordinary use, 10 GB is enough in the vast majority of cases — run the calculation just above.
What if I pick the wrong plan?
Money-back guarantee. And if you use more than expected, you can order a second eSIM in two minutes.
