AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not provide an unlimited data eSIM for Guam. Instead, the provider offers fixed‑data packages that are suitable for most travelers. For example, a 20GB plan for 30 days is available at $85.77 USD and a 10GB plan for 30 days is offered for $48.60 USD, both including tethering and 5G coverage across Guam and 117 other countries. Choosing one of these fixed‑data plans may be more cost‑effective for users who do not require unlimited data, while extremely heavy data users might still find the plans adequate with the large data allowances.

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.
