MoodSIM does not provide a truly unlimited data plan for Guyana. The plans titled “Guyana Unlimited” actually offer a fixed daily data allowance—500 MB, 1 GB, 2 GB, 3 GB or 10 GB per day—after which the connection speed throttles to a reduced rate (between 384 kbps and 1 Mbps). For travelers who need extensive data usage without speed reductions, MoodSIM offers fixed‑data bundles such as the 20 GB 30‑day or 10 GB 30‑day plans, which provide a larger allowance and consistent speed until the bundle expires.
