eSIM Firsty pour Cuba en 2026

No operator names are published for Cuba: Firsty has not said which networks it uses, so its radio side is unknown rather than bad; the practical details to check are in the table above. It lists 5G as the fastest technology, though that is an upper limit rather than a promise. With a large range of plans, sizing is the real decision, and the risk is buying more data than a fortnight needs. Top-up is stated as available, so an exhausted plan can be extended rather than rebought.
