Common questions

When should I install my eSIM?

You can install your eSIM anytime after purchase, but only activate it (turn on data) when you arrive at your destination to start your validity period.

Do I need to remove my primary SIM?

No! Your eSIM works alongside your existing SIM. You can switch between them in your settings or use both simultaneously (calls on primary, data on eSIM).

What if I run out of data?

You can purchase a top-up plan from your dashboard. Additional data packages can be added anytime during your validity period.

Can I use hotspot/tethering?

Yes! All our eSIM plans support hotspot and tethering, so you can share your connection with other devices.

How should I manage multiple eSIMs?

Two simple habits help. First, give each eSIM a name you'll recognize when you install it — your phone lets you label it (like "Japan trip") so you can always tell your eSIMs apart. Second, before adding a new eSIM, clear out any that have expired or that you've finished with — just double-check it's an old one. If you delete one by mistake, you can usually reinstall it on the same phone by tapping its original install link or re-scanning its QR code, as long as the plan is still valid, active and has data left — but an eSIM can't be moved to a different phone.
