eSIM guides, one airport at a time
The question as the wheels touch down is not whether the country has coverage — it is when the line comes up, and whether the airport Wi-Fi is needed to switch it on.
This index covers 87 airports across 20 destinations. Each page says where the line usually registers, what the free terminal Wi-Fi is good for, and what the ride into town asks of a data plan.
