No, nextSIM does not provide a truly unlimited data eSIM for Guyana. All plans that include “Unlimited” in the name have a data cap and specify a reduced speed after the limit is reached – for example, the eSIM Unlimited Standard and Plus plans offer 1GB or 2GB of high‑speed data per day and then slow to 512kbps or 2000kbps.
Travelers who need high‑speed data for longer periods can choose from nextSIM’s fixed data plans. For instance, a 20GB plan for 30 days in Guyana costs $91.77, and larger plans such as 30GB, 40GB, or 50GB for 30 days are available for $777.11, $1, 036.14, and $1, 295.18 respectively. These fixed‑data options can be more cost‑effective for heavy data users compared to the capped “Unlimited” plans.
