Comparez les eSIM pour East Asia en 2026

China, Japan and South Korea make for very different stops, but plan availability is fairly evenly spread across East Asia rather than resting on one or two markets. That means a regional option generally works as buyers expect for a cross-border itinerary, though coverage still varies by plan. The practical comparison is usually one regional eSIM against two or three single-country plans; which makes more sense often comes down to how many borders your trip crosses.
