GigSky eSIMs for French Indian Ocean Territories in 2026

Orange and SFR Réunion are the networks GigSky lists here, giving fallback options if one is thin outside cities. Traffic breaks out in the United States of America, so the round trip to local services is longer; video calls and gaming may feel it, while maps, messaging and browsing largely will not, and websites see a US address. 5G is the fastest technology GigSky states here, not a guarantee. With a large range, sizing the allowance matters: the risk is buying more data than a fortnight needs. GigSky does not say whether an exhausted plan can be topped up.
