Avelis eSIM does not provide any unlimited data eSIM for Guyana. All of the plans listed for Guyana have a defined data cap and a fixed validity period.
Travelers can choose from fixed data plans instead. For example, the Standard 20GB / 30 days plan costs $120.99 USD, and the Standard 5GB / 30 days plan costs $34.99 USD. These plans offer a set amount of high‑speed data for a fixed number of days and may be more cost effective for most users, unless the traveler is an extremely heavy data consumer.
