trifa does not offer any unlimited data eSIM plans for Guam.
The available plans provide a fixed data allowance; for example, a 100GB plan is available for 3, 5, 7, 10, and 15 days, with prices ranging from $23.11 USD to $93.32 USD. Choosing a fixed data plan can be more cost‑effective for travelers who need a large amount of data but are not extreme heavy consumers.
