eSIM Firsty pour Cayman Islands en 2026

Firsty has not published which operators it uses in Cayman Islands, so the radio side is unknown rather than a sign of poor coverage. It has also not published where traffic breaks out, so local latency and apparent IP location cannot be assumed. Its fastest stated technology is 5G, an upper limit rather than a promise. With a large range of plans, sizing is the main decision, though the risk is buying more data than a fortnight needs. Firsty says top-up is available, so an exhausted plan can be extended rather than rebought.
