eSimfly does not provide an unlimited data eSIM plan for the Republic of the Congo. The available offerings are fixed‑data plans, such as the Discover Global 20 GB 30 days plan for $48.18 USD and the Discover Global 20 GB 365 days plan for $83.66 USD, both of which include 20 GB of high‑speed data valid for the stated number of days.
Choosing a fixed‑data plan can be more cost‑effective for most travelers, especially those with moderate data needs. If a higher data allowance is desired, eSimfly also offers a 20 GB 30‑day plan for $101.31 USD or a 10 GB 30‑day plan for $29.70 USD. These plans provide a clear data limit and validity period, ensuring predictable usage without the uncertainty of an unlimited option.
