nextSIM does not provide a truly unlimited high‑speed eSIM for DR Congo. Plans labelled “Unlimited” actually offer a fixed amount of data—1 GB per day or 2 GB per day for a limited number of days—and once that allowance is used the speed is reduced to 512 kbps or 2000 kbps. The name “Unlimited” is therefore misleading.
If you need a fixed data plan instead, nextSIM sells several options. For example, the eSIM Democratic Republic of the Congo 10 GB 30 days Standard plan costs $114.56 USD, while the eSIM GLOBAL 20 GB 30 days Premium plan is available for $522.53 USD. These fixed‑data plans give a larger, non‑throttled data allowance and may be more cost‑effective for travelers who want to avoid the speed reduction that follows the “Unlimited” plans.
