AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not provide an unlimited data eSIM plan for Guam. Travelers can choose from fixed‑data options instead. For example, AdventureSIMs offers a 20GB plan that is valid for 30 days and costs $70.50 USD, or a 10GB plan for the same duration at $39.94 USD. These plans feature 5G connectivity in Guam and around 117 additional countries and allow tethering. Choosing a fixed‑data plan may be more cost‑effective unless the user is an extremely heavy data consumer.

AdventureSIMs does not provide a Guam eSIM that includes a phone number or SMS capability. The available Guam eSIM plans are strictly data‑only, so there is no inbound or outbound voice or SMS service included.

Travelers who need to communicate can use the data connection to run VoIP applications such as WhatsApp, Telegram or iMessage, which allow calls and messaging without a traditional phone number.

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.
