NextSIM does not provide a true unlimited data eSIM for French Guiana. All plans that carry the “Unlimited” label have a fixed data allowance—typically 1GB or 2GB per day—and specify a reduced speed once the cap is reached (for example, 512kbps or 2000kbps). Therefore, after the allotted data is used, the connection will be throttled rather than remaining fully high‑speed.
For travelers who need a larger, unthrottled data supply, NextSIM offers fixed‑data plans such as the eSIM French Guiana10GB 30Days Premium, which provides 10GB of data for 30 days, or higher‑capacity options like the eSIM GLOBAL 30GB 30Days Premium (30GB). These fixed‑data plans can be more cost‑effective for heavy data users compared to the “Unlimited” plans with daily caps.
