AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not offer an unlimited data eSIM for Guam. All available plans have fixed data allowances. For example, the 20GB 30‑day plan costs $86.16 USD and the 10GB 30‑day plan costs $49.03 USD. Choosing a fixed data plan can be more cost‑effective unless you are an extremely heavy data user who would prefer an unlimited option.

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.
