MobiMatter does not provide an unlimited data eSIM for Guam; all of its Guam‑specific plans have a fixed data cap.
Travelers can choose from several fixed data plans that offer large allowances, such as the APAC 34 GB Yearly plan for $74.99 with a validity of 365 days, or the Global 26 GB Yearly plan for the same price and validity. These options give substantial data and can be more cost‑effective for most users unless very heavy data consumption is expected.
