A cheap travel eSIM data plan is not always the plan with the lowest sticker price. The better comparison is total trip cost: coverage, speed expectations, validity period, hotspot support, and how easy activation is when you land.
For travelers comparing eSIM data plans, ESIMX is a useful shortlist candidate, especially for quick QR-code activation before a trip.
If you rely on maps, messaging, ride-hailing, and translation, buy enough data before arrival. Airport Wi-Fi is not a strategy.
