Yatelo does not provide a true unlimited data eSIM for Guam. Every plan listed for Guam has a fixed high‑speed data allowance, such as 2GB or 3GB, after which the speed drops to 1000kbps (or 384kbps for some global plans). Those plans are labeled “Unlimited” only because the data cap is delivered in a single block, not because the plan offers unlimited high‑speed usage.
If a traveler needs more data without a hard cap, Yatelo offers fixed data plans such as the GUM 20GB 30 Days plan at $64.49 USD, the GUM 10GB 30 Days plan at $35.49 USD, or the GUM 5GB 30 Days plan at $18.49 USD. These allow the specified amount of high‑speed data to be used over thirty days, giving a predictable data budget for the trip.
