vs. roaming
How it differs from carrier roaming
Home-carrier roaming can land as a large line on the bill. A travel eSIM charges the price you see at checkout. When the pack ends, data stops — nothing extra is billed in silence.

eSIM help centre →01Does my phone support eSIM?
Before you buy an eSIM, make sure your device supports eSIM and is not carrier-locked.
Search your model on the device list. Cellular iPads and many 2020+ flagship phones work. Wi‑Fi-only tablets and older phones usually do not.
02How do I install the eSIM?
After purchase, open My eSIMs. Scan the QR on Wi‑Fi, or use one-tap iOS / Android install.
iOS: Settings → Cellular → Add eSIM.
Android: Settings → Network & internet → SIMs → Add eSIM.
Turn on roaming for this line after you land.
03Is the quota daily or for the whole trip?
A 1-day pack is that day’s total. 7, 15, 30 and 180 day packs are one pool for the whole stay — they do not refill each morning. “10 GB · 30 days” means 10 GB across those 30 days.
04Can I share the connection or make calls?
Hotspot is included on the listed packs. These are data profiles, not voice minutes or classic SMS — WhatsApp, maps, mail and the browser run on data. Keep your main SIM if you still need your own number for calls.
05Can I cancel an eSIM?
Once the profile is issued, you cannot cancel it yourself. Unused profiles follow the refund policy. Choose the days and the GB before you pay.
06Setup problems?
If you have a problem with setup, you can open a ticket. We are happy to help.
