AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not provide a plan with unlimited data for Guam. Every plan listed for Guam limits data to a maximum of 20 GB over a 30‑day period.

Travelers can use fixed‑data plans as alternatives. For instance, the Global Essential 20GB 30 Days plan costs $71.28 USD, while the Global Essential 10GB 30 Days plan costs $40.39 USD. Choosing a fixed‑data plan can be more cost‑effective for users who need a substantial amount of data, whereas those who consume less data may find a lower‑cap plan sufficient.

AdventureSIMs does not offer a Guam eSIM plan that includes a phone number or SMS capability. Travelers can only purchase data‑only plans for Guam from this provider. For voice and messaging, users can rely on standard VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is advisable to check whether these apps are accessible in Guam before purchasing, as some destinations may block or restrict specific services.

AdventureSIMs currently offers five multi‑country data plans that include Guam; there are no single‑country plans for the territory. The available plans range in price from about $9.80 to $86.16, with data caps between 1 GB and 20 GB and validity periods of 7 to 30 days. Multi‑country plans give the data allowance for use in several destinations besides Guam, whereas a single‑country plan would restrict usage solely to Guam—a type that is not presently offered. Tethering is allowed on several of the plans.
