Stellar eSim does not provide a true unlimited data plan for Guam. The plans that carry the label “Unlimited” actually give a fixed high‑speed data allowance of 3GB, and once that amount is used the speed is reduced.
Travelers who need more data can choose from a range of fixed‑data options, such as the 20GB plan valid for 30 days, the 50GB plan valid for 180 days, or the 3GB plans that offer longer validity periods up to 300 days. These fixed‑data plans provide a clear data cap and a set validity window, and can be more cost‑effective unless a user requires extremely heavy data usage.
