eSIM FAQs
Common questions about using eSIM in Asia
What eSIM plans are ideal for cruise travel with port days in multiple countries?
Esimy regional plans are the best fit for cruise itineraries because they cover all common port countries on one eSIM — no need to buy a separate plan for every port. Pick the regional plan matching your cruise:
- Mediterranean / Greek Islands cruise — Esimy Europe regional (47+ countries, includes Italy, Greece, Croatia, Spain, France, Portugal, Cyprus, Malta) — €1.99 starting
- Adriatic / Balkans coastal cruise — Esimy Balkans regional (Albania, Croatia, Montenegro, Greece, and more) — €3.49 starting
- East Asia / Southeast Asia cruise — Esimy Asia regional (Japan, South Korea, Hong Kong, Taiwan, Thailand, Singapore, Vietnam, Indonesia, Philippines, Malaysia) — €3.49 starting
Important: Esimy connects to land-based mobile networks only. While at sea, you’ll need to use your ship’s satellite Wi-Fi or onboard cellular service (those are separate). The Esimy plan activates and works automatically once you reach port and your phone connects to a partner local carrier. 5% Loyalty Points back into your Esimy Wallet on every plan.

Is it better to use eSIM than local network?
