nextSIM does not provide a truly unlimited data eSIM for Republic of the Congo. All of its listed packages have finite data caps. For example, the eSIM Unlimited Standard 1 Day Congo plan gives 1GB of high‑speed data each day for $19.35 and reduces speed to 512kbps after the limit; the eSIM Unlimited Plus 1 Day Congo offers 2GB with a speed reduction to 2000kbps. For longer stays, a fixed‑cap option such as eSIM Congo 10GB 30Days Premium provides 10GB for $60.50, or the eSIM GLOBAL 50GB 30Days Premium supplies 50GB for $1, 279.81.
Because the capacities are limited, travelers who need large amounts of data may find a fixed‑cap plan more cost‑effective than an “Unlimited” package that merely throttles speed after the cap. Higher‑cap options like 20GB, 30GB, 40GB, or 50GB can be considered for heavy usage, but they still include a data limit and potentially reduced speeds once the cap is reached.
