Roamify offers unlimited‑data eSIM plans for the Republic of the Congo. The plans are available in one‑to‑thirty‑day periods, with prices ranging from $15.00 for a 1‑day plan to $266.00 for a 30‑day plan. Because the data cap is listed as Unlimited, the amount of data is not restricted; however, the provider indicates that speed may be throttled after heavy usage, reflecting a typical Fair Usage Policy. Most unlimited plans support 5G and allow tethering, but the exact speed levels and any throttling thresholds can vary, so travelers concerned about post‑usage speed reductions should contact Roamify directly for confirmation.
