Astaroam eSIM Data Plans for Guam

Astaroam does not offer an unlimited data eSIM for Guam. The plans listed for Guam stop at a maximum of 20GB of high‑speed data over 30 days. For travelers who want a larger data allowance, Astaroam provides fixed plans such as the Guam 20GB 30Days plan priced at $88.79 USD and the Guam 10GB 30Days plan priced at $47.66 USD. Choosing a fixed data plan can be more economical for most users, while an unlimited plan would be preferable only for very heavy data consumers who expect to exceed these limits.

Astaroam does not offer a Guam eSIM plan that includes a local phone number or SMS capability. The provider only sells data‑only eSIMs for Guam, so travelers must rely on internet‑based services such as WhatsApp, Telegram, or iMessage for calls and messaging.

Astaroam offers six single‑country plans for Guam, with no multi‑country options listed. The plans provide data caps ranging from 1 GB to 20 GB and prices between approximately $5.37 and $90.35, depending on the chosen data amount, validity period, and whether the plan includes features such as tethering.
