No, nextSIM does not provide a true unlimited data eSIM plan for the Republic of the Congo. The plans that contain “Unlimited” in their names are actually capped at 1 GB or 2 GB and, once that amount is reached, the connection is throttled to 512kbps or 2000kbps.
Travelers who need more data can choose from fixed data options, such as the 10 GB 30‑day plan priced at $61.43 or the 20 GB 30‑day plan at $519.81. nextSIM also offers 30 GB, 40 GB, 50 GB and 30‑day global bundles that include Republic of the Congo coverage. Selecting a fixed data plan may be more cost‑effective for those who anticipate a higher overall data usage.
