Roamable eSIM Data Plans for Guam

Roamable does not offer an unlimited data eSIM plan for Guam. The available options are fixed‑data plans, such as the Guam 20GB 30 days plan priced at $128.42 USD and the Global 20GB 90 days plan—which covers Guam and 117 other countries—priced at $203.30 USD. Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless a user needs data consumption that exceeds the plan limits.

Roamable does not provide a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for Guam.

Because a phone number or SMS is not available, travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

Roamable lists six single‑country data plans that cover Guam, in addition to seven multi‑country plans that include Guam as one of their destinations. Clients can choose from a price range of roughly $11.27 to $203.30, with data caps spanning from 1 GB to 20 GB, and validity periods between 7 and 365 days. The catalog also notes that several plans permit tethering, offering flexibility for users who need to share data across devices.
