Astaroam for Guam FAQ

Astaroam does not provide an unlimited data eSIM for Guam. The available plans are fixed data plans with specific data caps, such as the Guam 20GB 30Days plan and the Guam 10GB 30Days plan. These plans give a set amount of high‑speed data that must be used within the validity period. Choosing a fixed data plan can be more cost‑effective for most travelers, unless a user requires a very high volume of data that would exceed the caps of the available options.

Travelers can use the data allowance to access VoIP services such as WhatsApp, Telegram, or iMessage, but they should verify that these apps work in Guam before purchasing the plan.
