Silvy eSIM Data Plans for Guam

Silvy does not provide an unlimited data eSIM plan for Guam. The available options are fixed data plans that must be used within a set validity period. For example, the Guam 20GB for 30 Days plan offers 20GB of high‑speed data for 30 days, while the Guam 10GB for 30 Days plan provides 10GB for the same period. These fixed data plans can be more cost‑effective for most travelers, unless a user requires a very high data volume that would exceed the available bundles.

Silvy does not offer a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available from Silvy for Guam. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are accessible in Guam before purchasing.

Silvy has five single‑country data plans that are available specifically for Guam. In addition, an extra four multi‑country plans include Guam as part of their coverage. The single‑country options provide dedicated data for Guam alone, whereas the multi‑country plans allow the same data allocation to be used across several destinations. Across all Silvy plans for Guam, prices range from about $14.90 to $72.50 USD, data caps vary from 1 GB to 20 GB, and validity periods span from 7 days up almost 90 days.
