Short answer
An eSIM can provide data from the first leg and reduce reliance on unknown Wi-Fi. Install at home and monitor usage if you use maps, video, or hotspot heavily.
Checklist
- Install before departure over Wi-Fi
- Select the correct data line before booking transport
- Download hotel and travel information for areas with variable access
Common question
Is an eSIM useful for island hopping?
It can be useful because you want data between hotels, transport, and activities without arranging a new solution at every leg.
