Avelis eSIM does not provide an unlimited data eSIM for Guam. All of the plans listed for Guam have a fixed data cap, with the largest available options offering 20GB of data.
Travelers who need a larger data allowance can choose one of the fixed data plans, such as the Standard 20GB / 30 Days plan or the Standard 20GB / 90 Days plan. These plans give a set amount of data that must be used within the specified validity period, and they can be more cost‑effective for most users unless a traveler requires a very high volume of data.
