Saily eSIM Data Plans for Guam

Saily does not provide a truly unlimited data eSIM for Guam. All Saily plans listed for Guam have a fixed data cap— the largest is 30 GB, and the plan name “UNLIMITED” only indicates that the data allowance is stuck at 30 GB before a reduced speed is applied (1 kbps or 1000 kbps depending on the package).

Travelers who need a large amount of high‑speed data can consider the fixed data plans such as the 30 GB 90‑day plan for $119.99 USD, the 20 GB 365‑day plan for $66.99 USD, or the 15 GB 90‑day plan for $79.99 USD. These fixed plans offer a substantial data allowance and may be more cost‑effective for users who are not extremely heavy data consumers.

Saily does not offer eSIM plans for Guam that include a phone number or SMS capability. Only data‑only plans are available from the provider.

Travelers who need phone‑like voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict or block those services, so users should confirm that the apps they depend on work in Guam before buying a plan.

Saily offers a single-country plan that covers only Guam, alongside a separate set of multi‑country plans that include Guam within a broader coverage network. In total, there is 1 single‑country deal for Guam and 11 multi‑country packages that list Guam among their destinations. Prices for these plans range from about $8.99 to $159.99, while data capacities span from 1 GB up to 30 GB, providing options for both short‑term travelers and those needing more extensive usage.
