FAQ
Questions worth asking
Most phones released in recent years do — including iPhone XS and newer, Google Pixel 3 and newer, and many Samsung Galaxy models. The app checks your device before you buy, and the supported-device list is available in-app.
No. Your normal SIM stays in the phone and keeps working for calls and SMS. ZeSIM runs alongside it purely for mobile data, and you can switch data back at any time.
Your plan activates when the eSIM first connects to a network at your destination — not when you buy it. So it is safe to purchase days before you travel.
Top up the same eSIM from the app — no need to install anything new. Adding the same plan again extends your data; you will be warned in-app before switching to a different plan.
Tethering support depends on the local network operator for your plan. Where it is supported, you can share your connection as usual from your phone settings.
Reach us at support@example.com and include your eSIM ICCID from the app — it lets us look up your plan straight away.
Your next trip deserves better than airport Wi‑Fi.
