AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not offer an unlimited data eSIM for Guam.
Instead, the provider sells fixed‑data plans. Among the options available are the Global Essential trips ranging from 1GB for 7 days up to 20GB for 30 days, all of which provide high‑speed 5G coverage in Guam and 117 additional countries. Choosing one of these fixed‑data plans can be a more cost‑effective choice unless you anticipate extremely heavy data usage.

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.
