Astaroam eSIM Data Plans for Guam

Astaroam does not provide a truly unlimited high‑speed data eSIM for Guam. The plans named “Unlimited” give 2GB of 5G/4G data per day, and after that limit is reached the speed drops to a reduced 1000kbps. Travelers who need higher data allowances could choose one of Astaroam’s fixed‑data plans, such as the 20GB plan valid for 30 days or the 10GB plan also valid for 30 days. These fixed plans may offer a better cost‑effective solution for moderate to heavy data usage.

Astaroam does not offer eSIM plans for Guam that come with a phone number or SMS capability. Only data‑only plans are available. 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.

Astaroam provides nine single‑country data plans for Guam, with no multi‑country offerings available. The plans span a price range from about $3.83 to $50.57 and cover data caps between 1 GB and 20 GB. Within the single‑country selection, three plans feature daily data caps while the remaining six offer fixed data amounts over the plan’s validity period. This range gives travelers several options for short‑term data needs in Guam, with varying price points and data limits.
