nextSIM’s plans that carry the word “Unlimited” in their names do not provide truly unlimited high‑speed data in Gabon. These plans give a fixed allowance of 1 GB or 2 GB per day or for the total validity period, and once that limit is reached the connection speed is reduced to 512 kbps for the Standard variants or 2000 kbps for the Plus variants.
For travelers who need more data without a speed drop, nextSIM offers fixed‑data options such as the eSIM GLOBAL 50 GB, 40 GB, 30 GB, or 20 GB plans for 30 days, and the eSIM Gabon 10 GB 30‑day plan. These plans give large data allowances over a month and may be more cost effective for heavy data users.
