nextSIM does not provide a truly unlimited data eSIM for Republic of the Congo. The plans that carry the title “Unlimited” actually include a fixed data allowance—1GB or 2GB per day for the available durations. After that allowance is used, the speed reduces to a throttled rate: 512kbps for the Standard plans and 2000kbps for the Plus plans.
Travelers who need more data can choose from nextSIM’s fixed‑data plans, which offer larger caps. For example, the eSIM Congo 10GB 30‑day Premium plan gives 10GB of full‑speed data, while the global plans range from 20GB to 50GB for 30 days. These options allow full‑speed data until the cap is reached, after which no additional data is provided.
