ZenSim does not provide a truly unlimited data eSIM for Guyana. All plans listed for this destination have a fixed data allowance and a set validity period. For example, the largest high‑speed bundles include a 10 GB plan valid for 15 days or 30 days, and a 5 GB plan valid for 5 days, 15 days or 30 days.
The plan titled “Guyana Unlimited STANDARD – 5 Days” is not an unlimited offer; it provides only 3 GB of high‑speed data per day, after which the speed drops to 1000 kbps. Travelers who need more data can choose one of the fixed data bundles instead, which may be more cost‑effective unless extremely heavy data use is anticipated.
