NextSIM does not provide a true unlimited data eSIM for travellers to the Republic of the Congo. All plans listed under the “Unlimited” name give a short daily allowance – either 1 GB or 2 GB per day – and once the limit is reached the network speed drops to a reduced rate of 512 kbps or 2000 kbps. Because of this cap, the plans are not unlimited in the sense of giving high‑speed data without limits.
If you need more data, you can choose a fixed‑data plan instead. For example, the eSIM GLOBAL 30GB 30Days Premium offers 30 GB of data for 30 days, while the eSIM Congo 10GB 30Days provides 10 GB for the same period. These options give you a larger amount of high‑speed data at a single price and are often more cost‑effective for heavy data users.
