EZsim does not offer an unlimited data eSIM for Guam. The only options available in Guam are fixed‑data plans with specific caps and validity periods. These include the 20GB plan for 30 days priced at $99.95 USD, the 10GB plan for 30 days at $50.45 USD, the 5GB plan for 30 days at $25.70 USD, the 3GB plan for 15 days at $15.80 USD, and a 1GB daily plan for 1 day at $5.70 USD. Each of these packages has a hard data limit and expires according to its stated validity once activated.
For travellers who need a large amount of data, selecting one of these fixed data plans can be more cost‑effective than purchasing a pay‑as‑you‑go approach, unless the user is an extremely heavy data consumer who would prefer a truly unlimited experience.
