eSIM YeSIM pour Cuba en 2026

YeSIM has not published which operators it uses in Cuba, where its traffic breaks out, or the fastest technology it lists, so the radio side, apparent IP location and performance ceiling are unknown rather than bad. With a dozen or so plans, the sizing decision is the real one: the risk is buying more data than a fortnight needs. YeSIM also does not say whether top-up is available, so check before buying whether an exhausted plan can be extended or must be replaced.
